BACKGROUND OF THE INVENTION
  The present invention relates to improvement of a shoe sole, particularly a shoe sole pattern, which can be used for daily general purposes other than golf, while being a shoe most suitable for golf.
[0002]
[Prior art]
  Conventionally, as a shoe sole of a golf shoe, there is a shoe sole provided with a plurality of metal or rubber protrusions.
  Such shoe soles are roughly classified into the following three types. The first shoe sole is a shoe sole of a golf shoe that stops a shoe from slipping by piercing a lawn with a metal or rubber protrusion (see Patent Document 1).
  Further, the second shoe sole is a shoe sole formed with projections randomly oriented in multiple directions (see Patent Documents 2 to 6).
  And the 3rd sole is the sole which has arrange | positioned the protrusion mainly in the front-back direction (refer patent documents 7-9).

[Problems to be solved by the invention]
  However, the above-described golf shoes and the like still have room for improvement in terms of improving the anti-slip performance in the golf swing which is a very complicated motion.
[0005]
  The shoe sole provided with the metal protrusion of Patent Document 1 has a feeling of being pushed up from the shoe sole, or the road surface when walking on a road surface of a walking path provided in a golf course, a clubhouse or the like. There were problems such as hurting the floor. In addition, there is a danger that a shoe sole provided with a metal protrusion slips on a slope where there are many concrete ones. In addition, in recent years, shoe soles with metal protrusions have been less preferred and used for golf shoes in order to damage the patent green.
[0006]
  On the other hand, the shoe soles of Patent Documents 2 to 6 are prone to slip on the grass, but the stability on the grass surface is poor and slippery. For example, when the weight during walking is placed on the entire sole, there is a problem that the sole tends to slip with the lawn surface. In addition, when walking on the asphalt surface, the projections are worn, and the damage is severe, and there is a problem in durability and shock absorption. These shoe soles are considered not to be in harmony with grips during swing and walking, have poor stability, and are not suitable for general daily use.
[0007]
  Moreover, the shoe sole of patent documents 7-9 cannot respond | correspond all of the force which acts on a shoe sole at the time of a golf swing. Therefore, an optimal grip force cannot be obtained on the grass surface during golf swing, and the shoe sole may slip with the grass surface. When slipping occurred, there was a problem that the swing form was disturbed and accurate hitting could not be performed.
[0008]
  As a result of analyzing the force vector (ie, magnitude and direction) applied to the foot from the top position to the impact, the present inventor has found the following. In other words, as the main direction of the force applied during the golf swing, when the front of the shoe is set to the 12 o'clock direction, the right foot works radially from the center of the sole of the foot from 3 o'clock to 6 o'clock, The left foot works radially from the center of the sole counterclockwise from 2 o'clock to 8 o'clock (or around 7 o'clock) (see Fig. 2). In this case, the description is for a case where the golf player is right-handed.
[0009]
  That is, according to the analysis by the present inventor, in the golf swing, the force is not applied only in two directions from the heel to the toe at the shaft foot, but acts radially, and as the swing progresses, Transition. Specifically, the force applied during takeback works radially from 2 o'clock to 4 o'clock on the left foot of a right-handed player. At the top position, the force is mainly applied to the rear of the foot hitting direction (the direction of about 5 o'clock closer to the inside for the golfer's axle foot). In accordance with the progress of the swing from the downswing to the impact, the position where the force is applied shifts radially to the center of the foot (in the direction of about 3 o'clock) in time series. As the swing progresses from impact to follow-through, the direction of the force also moves to the full toe direction (about 12 o'clock), and further forward (about 11 o'clock near the outside for the golfer's axle) ), And from the slightly forward-facing toe direction to the arch direction (about 8 o'clock direction) over time. That is, the force applied from the top to the follow-through works radially from 2 o'clock to 8 o'clock (or about 7 o'clock) and shifts.
[0010]
  Next, in the kick leg, the force works radially rather than in two directions from the toe toward the heel, and shifts with time as the swing progresses. In detail, in the takeback, the force is mainly applied to the rear side of the hitting direction of the foot (about 1 o'clock side of the outside for the golfer's kicking foot). From the start of the takeback to the top, the position where the force is applied is mainly to the center of the foot (about 3 o'clock direction) and to the rear (about 6 o'clock direction of the outside for golfer's kick foot) 3 It moves radially from time to 6 o'clock and moves.
[0011]
  On the other hand, the center part of the shoe sole is an important part for exerting a grip force when a load by a wearer of the shoe sole is applied in a direction orthogonal to the shoe sole, and the peripheral part of the shoe. This requires different consideration from the shape of the sole.
[0012]
  In view of the above problems, the present invention has been made on the basis of the above knowledge. The purpose of the present invention is an emergency in which the direction of the force applied to the shoe sole changes with time when walking on the lawn surface. In addition to providing optimal grip on the lawn surface during golf swing, which is a very complex exercise, it can prevent damage to the golf course or clubhouse floor, and walking on asphalt surfaces, etc. Providing a shoe sole with excellent convenience that can be used for shoes for general everyday use regardless of the lawn surface or asphalt surface. It is to be.
  Furthermore, the objective of this invention is aiming at harmony with the grip power at the time of golf swing and walking, and providing the shoe sole provided with the outstanding stability.
[0013]
[Means for Solving the Problems]
  The shoe sole according to the present invention pursued the optimum grip force in consideration of the following points when developing a shoe sole having an optimum grip force on the lawn during golf swing.
  1. Arrangement and shape of columnar protrusions that produce the optimal grip direction during swing
  2. Arrangement of columnar protrusions suitable for meshing with turf stems, roots or leaves, and gaps and shapes of adjacent columnar protrusions
  3. Difference in height of columnar protrusion (high point and low point)
  4). Difference in hardness of columnar protrusion (hard point and soft point)
  5. Ratio of contact area in the hardness of columnar protrusion (area ratio of hard point and soft point)
  6). Shape and arrangement of columnar protrusions that produce stability and adequate grip during walking
  7. Sole material
[0014]
  Hereinafter, each item will be described.
  1. Arrangement and shape of columnar protrusions that produce the optimal grip direction during swing
  In the shoe sole according to the present invention, a plurality of types and a plurality of types of columnar protrusions are arranged to face different directions on the outer edge portion of the back surface of the shoe. That is, the first and third columnar protrusions are arranged in a portion corresponding to about half of the outer side of the arc or elliptical arc with the first columnar protrusion as the center, and the second and third columnar protrusions are arranged on the side surfaces of the columnar protrusions. The wall-shaped non-slip surface to be constructed is arranged so as to face various directions. In particular, if the second columnar protrusion is arranged in a direction whose one side surface is orthogonal to the direction of the force applied when the golf player swings, the force can be accurately received, which is effective.
[0015]
  Furthermore, the second columnar protrusions are portions corresponding to about half of the outer side of the arc or elliptical arc with the first columnar protrusion as the center, and are arranged at three locations facing the side, diagonally forward and forward of the shoe. . Further, the columnar protrusion group arranged in an arc shape or elliptical arc shape including the second columnar protrusion is treated as if it were one unit protrusion, and a wall-shaped non-slip surface constituted by one side surface of the second columnar protrusion is provided. When multiple golf balls are arranged in different directions, they can be opposed to the force generated on the sole of the shoe continuously from the center of the shoe toward the outside during the golf swing. It is possible to produce a strong gripping force because it can handle almost all of the force that works around and radially.
[0016]
  2. Arrangement of columnar protrusions suitable for meshing with turf stems, roots or leaves, and gaps and shapes of adjacent columnar protrusions
  The columnar projections are arranged as described above, and the columnar projections are arranged at appropriate intervals so as to have an appropriate gap between the columnar projections so that a lawn stalk, root, or leaf enters and strongly fits. To do. Thus, by considering the arrangement of the columnar protrusions suitable for meshing with the lawn stems, roots or leaves and the gap and shape of the adjacent columnar protrusions, the gap between the adjacent columnar protrusions is Since the stem, root, or leaf enters and fits strongly, it is possible to produce a strong grip. The gaps between the columnar protrusions are in the range of approximately 1.0 mm to 6.0 mm, that is, approximately 1.0 mm, approximately 2.0 mm, approximately 3.0 mm, approximately 4.0 mm, approximately 5.0 mm, and approximately 6.0 mm. It is preferable to select from the above.
[0017]
  3. Difference in height of columnar protrusion (high point and low point)
  In order to increase the grip force, two types of columnar protrusions having different heights are provided. Of the two types of columnar projections, one columnar projection is formed in an elongated shape, so that the ground contact area is reduced, and it has the effect of being easily pierced into the grass surface and firmly biting into the grass. Further, the other columnar protrusions are formed thick and short so as to be shorter than one columnar protrusion, so that the ground contact area is large and the lawn is easily pressed, and has an effect of appropriately biting into the lawn and generating stability. That is, the balance between the heights of the two types of columnar protrusions improves the grip (see FIG. 4).
[0018]
  Furthermore, the height of the other columnar protrusions is made shorter than that of one columnar protrusion, and the two types of columnar protrusions are provided on the back surface so as to form an appropriate distance from each other, thereby widening the surface area of the turf. be able to. The surface area of the turf can be increased by about 10% compared to when the turf is bitten by the columnar protrusions of the same height (see FIG. 7).
[0019]
  4). Difference in hardness of columnar protrusion (hard point and soft point)
  That is, the hardness corresponding to the above-described columnar protrusions 3 having different heights is set. One columnar protrusion acts as a tall point and has a hard hardness (JIS-A hardness 75 degrees) in order to improve the digging of the turf so as not to lose the force of golf swing. The other columnar protrusions act as a short point, improve stability, and absorb the push-up during walking, and have a soft hardness (JIS-A 65 degrees). By doing so, the turf biting and stability by columnar protrusions of different heights can be further improved.
[0020]
  5. Area ratio in the hardness difference of columnar protrusion (area ratio of hard point and soft point)
  That is, the shoe sole according to the present invention can be gripped in a well-balanced manner since the first columnar protrusions having a hard hardness and the second columnar protrusions having a soft hardness have the same area ratio into the turf.
[0021]
  6). Shape and arrangement of columnar protrusions that produce stability and adequate grip during walking
  By making the shape of the columnar protrusions with respect to walking a jagged shape and arranging the points (columnar protrusions) in a staggered manner, a strong grip force with respect to the front and back walking is created (see FIG. 8A).
  Moreover, when walking on a hard road surface, a moderate cushioning property is born by a jagged portion being bent, and an effect of reducing the burden on the foot is obtained (see FIG. 8B).
  Further, when used on a rainy day, the knurled grooves discharge water appropriately, so that the grip power is excellent even on wet road surfaces.
[0022]
  7. Sole material
  By making the shoe sole material an anti-wear rubber with an oil additive with an optimal composition, it is possible to prevent damage to the golf course or clubhouse floor, and even if walking on the asphalt surface, etc. Less wear and damage, excellent durability and shock absorption.
[0023]

DETAILED DESCRIPTION OF THE INVENTION
  An embodiment of the present invention will be described based on an example with reference to the drawings. FIG. 1 relates to the present invention.Left footShow the appearance of the solePerspective bottom viewIt is. As shown in FIG. 1, the shoe sole 10 has a plurality of columnar protrusions 1, 2, 3, 4, 5, 6, and 7 made of synthetic rubber on the back surface of the shoe.
[0042]
  In order to obtain an optimum grip force by harmonizing an appropriate grip force during golf swing and an appropriate grip force during walking, the shoe sole 10 has columnar protrusions 1, 2, 3, 4 as follows. , 5, 6 and 7 are arranged.
[0043]
  First, the columnar protrusions 1, 2, 3, 6, and 7 are formed so that the shoe soles 10 are spaced from each other at an appropriate interval in order to obtain an optimal grip force during a golf swing that grips the shoe sole 10 in an inclined posture. Are arranged on both left and right sides. On the other hand, the columnar protrusions 4 and 5 are spaced apart from each other in the center of the shoe sole 10 in order to obtain an optimum grip force during walking when the weight is put on the entire shoe sole 10 or when going up and down the slope. A plurality are arranged in the section.
[0044]
  As shown in FIGS. 2 and 3, the columnar protrusions 1, 2, 3 are formed to be longer and shorter than the columnar protrusions 1, 2, and the columnar protrusions 1, 2, which are easy to pierce the lawn surface. The columnar protrusions 3 are arranged on the back surface so as to form an appropriate distance from each other., (In the installation position of each columnar projection)Counterclockwise force F of about 2 o'clock to about 8 o'clock applied to the left foot of a right-handed golf player whose wall-shaped non-slip surface formed by the side surfaces of each of the columnar protrusions 1, 2, 3 is swinging₁₁~ F₁₈In the direction of time(Sequentially)Correspondingly, the columnar protrusions 1, 2 and 3 are arranged in different directions from the toe of the left foot toward the outer edge of the back of the shoe corresponding to the arch. Of course, the arrangement of the columnar protrusions 1, 2 and 3 is such that the counterclockwise force F between about 2 o'clock and 7 o'clock applied to the left foot during the swing described above.₁₁~ F₁₉The arrangement corresponding to the direction of time may be possible.
[0045]
  Similarly, a wall-like anti-slip surface constituted by the side surfaces of the columnar protrusions 1, 2, 3 is provided., (In the installation position of each columnar projection)Clockwise force F of about 3 to 6 o'clock on the right foot after the swing of a right-handed golf player₂₁~ F₂₅In the direction of time(Sequentially)Correspondingly, the columnar protrusions 1, 2 and 3 are arranged in different directions from the toe of the left foot toward the outer edge of the back of the shoe corresponding to the arch.
[0046]
  Further, at the left and right outer edges of the back of the shoe corresponding to the heel from the arch of the left foot, the wall-shaped non-slip surface constituted by the side surfaces of the columnar protrusions 1, 2, and 3 has a right-handed golf player swinging. Corresponds to the time direction of the counterclockwise force from about 2 o'clock to about 8 o'clock on the left foot of the player and the time direction of clockwise force from about 3 o'clock to about 6 o'clock on the right foot after the player starts swinging. As described above, the columnar protrusions 1, 2, and 3 are arranged.
[0047]
  Further, as shown in FIG. 4A, the columnar protrusions 1, 2, and 3 are formed so that the columnar protrusions 3 are 0.5 mm to 3.0 mm shorter than the columnar protrusions 1 and 2 that are easily pierced into the grass surface. Various directions that make it easy to press, and are arranged on the semicircle or semi-ellipse that form an arc on the outer edge side of the shoe so as to form an appropriate distance from each other, and the gaps formed between the columnar protrusions are different. It is made to face. Thereby, as shown in FIG. 4B, the relationship between the shoe sole 10 and the grass surface in golf is such that the grass stems, roots or leaves enter the gaps formed between adjacent columnar protrusions. It fits tightly, can respond to different force directions, and can produce a strong grip.
[0048]
  That is, the columnar protrusions 1, 2, 3 are arranged on the back surface so as to form an appropriate distance from each other, and the second and second portions are located at portions corresponding to about half of the outer side of the arc or elliptical arc with the first columnar protrusion 1 as the center. Three columnar protrusions 2 and 3 are arranged.
[0049]
  As shown in FIG. 5, the plurality of columnar protrusions 1, 2, 3CornerThe columnar protrusions 2 are formed by changing the arrangement angle so that the side surfaces of the columnar protrusions 2 face different directions. Thus, when the plurality of columnar protrusions 2 are arranged so as to face in various different directions, the shoe sole 10 that changes radially from the shoe central portion that changes with time during the golf swing toward the outer portion is formed. It is possible to deal with the directions of the forces F11 to F19 in different directions, and an optimum grip force can be obtained.
[0050]
  In other words, as shown in FIG. 6, these columnar protrusions 1, 2 and 3 are arranged such that the columnar protrusions 2 are radially arranged around the columnar protrusions 1, and the columnar protrusions 3 are arranged between the columnar protrusions 2. The columnar protrusions 1, 2, and 3 are arranged side by side in a substantially semicircular arc shape, and the outer side surfaces of the plurality of columnar protrusions 2 arranged in the semicircular arc shape are lateral to the shoe during the swing.F ₁₇ ,Diagonally forwardF ₁₅ And forwardF ₁₃ It is formed in the direction opposite to the force generated continuously toward(FIGS. 2, 3, and 5 show the correspondence between the direction of the force F and the outer surface of each columnar protrusion.)
[0051]
  The columnar protrusion 1 is formed in a particularly long and substantially cylindrical shape, and is easy to penetrate to the root of the lawn, so that the area of the tip of the columnar protrusion 1 is smaller than the area of the base end of the columnar protrusion 1. It is formed. That is, it is formed in a tapered columnar shape whose longitudinal section is substantially trapezoidal. Moreover, the hardness of the columnar protrusion 1 is selected from the range of JIS-A hardness 65 to 90 degrees.
[0052]
  The columnar protrusion 2 is formed in a substantially triangular column shape, and is formed so that the area of the tip end portion of the columnar protrusion 2 is narrower than the area of the base end portion of the columnar protrusion 2. That is, it is formed in a tapered prismatic shape whose longitudinal section is substantially trapezoidal. Further, the hardness of the columnar protrusion 2 is selected from the same hardness range as that of the columnar protrusion 1.
[0053]
  Further, the columnar protrusion 2 is arranged in a direction in which one side surface of the columnar protrusion 2 is orthogonal to the direction of the force applied when the golf player swings, and is appropriate for the force applied to the shoe sole 10 during the golf swing. The grip power can be demonstrated.
[0054]
  Further, when two elongated grooves 2a formed at appropriate intervals in the vertical direction from the front end portion to the base end portion are provided on the side surface of the columnar protrusion 2, an anti-slip effect can be further exhibited. Further, the side grooves 2a exhibit an excellent drainage effect, and for example, an excellent grip force can be exhibited even when the lawn surface is wet.
[0055]
  Further, the columnar protrusion 3 is formed in a substantially hexagonal columnar shape, and is formed in a tapered substantially hexagonal columnar shape so that the longitudinal section of the columnar protrusion 3 is substantially trapezoidal like the columnar protrusions 1 and 2. The height of the columnar protrusion 3 is formed lower than the height of the columnar protrusions 1 and 2. An elongated slit-shaped recess 3 a is formed on the grass contact surface at the tip of the columnar protrusion 3. Thereby, while having a drainage effect, a front-end | tip part is easy to bend and it is easy to press a lawn.
[0056]
  Further, as shown in FIG. 7, the columnar protrusion 3 is a columnar protrusion that is formed to be thicker and shorter than the columnar protrusions 1 and 2 and facilitates pressing of the lawn. Further, the hardness of the columnar protrusion 3 is set within a range of JIS-A hardness 55 to 80 and lower than the columnar protrusions 1 and 2. Therefore, the hardness of the columnar protrusions 1 and 2 is higher than the hardness of the columnar protrusion 3. Thus, when the hardness of the columnar protrusions 1 and 2 is higher than the hardness of the columnar protrusion 3, the columnar protrusions 1 and 2 are more likely to pierce the lawn surface, and the bite into the grass is improved. We do not lose power at the time of golf swing. Also, with this configuration, the hardness of the columnar protrusion 3 is lower than the hardness of the columnar protrusions 1 and 2, so that the stability can be improved and the push-up during walking can be absorbed.
[0057]
  Further, the columnar protrusion 3 is selected from the range of the area ratio of 1: 1 to 1: 3 in the area of the tip of the columnar protrusions 1 and 2 having high hardness and the area of the tip of the columnar protrusion 3 having low hardness. In this case, the ratio of the area where the columnar protrusions 1 and 2 bite into the turf and the area where the columnar protrusion 3 bites into the turf is equal to or greater than the former, so that the grip can be performed with a good balance.
[0058]
  On the other hand, as shown in FIG. 8, the columnar protrusions 4 and 5 having a plurality of grooves 11 facing the left and right directions at the distal end are spaced apart from each other on the shoe sole 10 as shown in FIG. A plurality of them are arranged in the center of the shoe sole. The front part of the shoe sole 10 is provided with about 24 pieces in three rows, the central part is provided with about 12 pieces in two rows, and the rear part is provided with about 17 pieces in three rows. It occupies about 25% to 50%. In this embodiment, the front part is set to about 40% of the shoe sole, the central part is set to about 25%, and the rear part is set to about 60%.
[0059]
  The columnar projections 4 and 5 are portions that are important for exerting a grip force mainly when a load applied by a shoe wearer is applied in a direction perpendicular to the sole, and during golf swing and walking Columnar protrusion 4 having a tip surface formed in a slope shape so that the height from the shoe sole increases toward the front, and the rear The columnar protrusions 5 whose tip surfaces are formed in an inclined shape so that the height from the shoe sole 10 is increased are arranged alternately.
[0060]
  Further, the columnar protrusions 4 and 5 are formed so that only the highest tip is flat. On the other hand, the other end of the plurality of saw-toothed columnar protrusions 4, 5 has a recess 12 that increases the locking force in the left-right direction so as to skip one tooth in the front-rear direction. Is formed. Further, the columnar protrusions 4 and 5 are formed in a square columnar shape having a substantially trapezoidal bottom surface in which the side with the higher height from the shoe sole 10 is longer than the side with the lower side.
[0061]
  Further, the columnar protrusions 4 and 5 are arranged in a plurality of rows in the front-rear direction of the shoe, and their positions are shifted from each other in the left and right rows. The height of the columnar protrusions 4 and 5 is selected such that the maximum height is within a range of about 3.0 mm to 7.0 mm from the sole 10, and the minimum height is about 1 from the sole. Selected from the range of 0.0 mm to 5.0 mm.
[0062]
  The columnar protrusions 6 are formed in a substantially square column shape, and are formed on the peripheral edge of the shoe sole 10 with an appropriate interval around the entire circumference. The height of the columnar protrusion 6 is lower than the height of the columnar protrusion 3. The hardness of the columnar protrusions 6 is equivalent to the hardness of the columnar protrusions 3 and makes it easy to press the lawn. Thus, the columnar protrusions 1, 2, and 3 are supplemented, the stability of the shoe sole 10 is reinforced, and the push-up feeling is eliminated.
[0063]
  The columnar projection 7 has a substantially Z-shaped columnar tip, and a shoe corresponding to the foot arch so that a wall-shaped non-slip surface constituted by one side of the substantially Z-shape corresponds to the side-sliding direction of the shoe sole. It is arranged outside the outside of the bottom 10. Furthermore, it is formed in a shape that is combined with a substantially triangular prism shape in which the height from the shoe sole 10 gradually decreases in the outside direction toward the inside direction of the shoe sole 10. The height of the columnar protrusion 7 is such that the height of the leading edge on both sides of the substantially Z-shaped columnar shape is equivalent to the height of the columnar protrusions 1 and 2, and the height of one side that is the central portion of the substantially Z-shaped columnar shape, The height is the same as the height of the columnar protrusion 3. The hardness of the columnar protrusion 7 is equivalent to the hardness of the columnar protrusions 1 and 2 and is higher than the hardness of the columnar protrusion 3. Therefore, the columnar protrusion 7 can be easily stabbed into the lawn surface, can press the lawn, can capture the lateral force applied to the shoe sole 10 that causes skidding, and is effective for skidding. .
[0064]
  FIG. 9 is a bottom view of the entire shoe sole 10 showing the arrangement of the columnar protrusions 1, 2, 7 with high hardness and the columnar protrusions 3, 4, 5, 6 with low hardness. As shown in FIG. 9, the shoe sole 10 has areas of tip portions of the columnar protrusions 1, 2, 7 having high hardness represented by oblique lines rising to the right, and tip portions of the columnar protrusions 3, 4, 5, 6 having low hardness. The area of is indicated by a diagonal line rising to the left. The area of the tip portions of the columnar protrusions 1, 2, 7 having high hardness and the area of the tip portions of the columnar protrusions 3, 4, 5, 6 having low hardness are within a range of about 1: 1 to 1: 3. That is, if the selection is made from 5: 4, 1: 1, 2: 3, 1: 2, 1: 3, etc., the area where the columnar protrusions 1, 2, 7 bite into the grass and the columnar protrusions 3, 4, 5 , 6 bite into the turf, the ratio of the latter is greater than that of the former, and the grip can be gripped in a well-balanced manner.
[0065]
  As shown in Table 1, each of the columnar protrusions 1 to 7 is made of an anti-wear rubber containing an oil additive in which rubber, oil, and a stabilizer are blended at a predetermined ratio.
[0066]
  FIG. 10 is a bottom view of the entire shoe sole 10 showing the shoe sole 10 according to the present invention and the direction of the force applied to the shoe sole 10 in the first half of the swing, and FIG. 11 shows the shoe sole 10 and the swing according to the present invention. FIG. 12 is a bottom view of the entire shoe sole 10 showing the direction of the force applied to the shoe sole 10 in the middle half, and FIG. 12 shows the direction of the force applied to the shoe sole 10 according to the present invention and the shoe sole 10 in the latter half of the swing. It is a bottom view of the shoe sole 10 whole which shows. As shown in FIGS. 11 to 13, the golf swing is arranged to accurately capture different directions that change with time, and has an excellent grip force.
[0067]
  In this way, the plurality of columnar projections 1, 2, and 3 are arranged on the left and right sides of the back of the shoe in various desired directions, so that the optimal position that the golfer's foot should grip is desired. With this, you can get the best grip. In addition, the arrangement positions of the plurality of columnar protrusions 1, 2, 3 are on the left and right side parts, and the difference in hardness, height difference, and tip area ratio of the columnar protrusions 1, 2, 3 is improved. When the load is applied to the entire shoe sole 10 or the grip force during walking is not hindered.
[0068]
   In addition, it can prevent damage to the floor surface of clubhouses, etc., and even when walking on an asphalt surface, etc., there is little wear and damage on the protrusions, excellent durability and shock absorption, It can be used for shoes and has excellent convenience.
[0069]
  Furthermore, by arranging the columnar protrusions 4 and 5 in the center portion of the shoe sole 10 as described above, it is possible to harmonize the grip force during golf swing and walking, thereby providing excellent stability. it can. That is, (1) the shape of the ground contact surface of the columnar protrusions 4 and 5 (cross-sectional shape in the horizontal direction with the shoe sole) is trapezoidal, and (2) the direction of the protrusions 4 and 5 adjacent to the left and right is the backward and forward direction. (3) The columnar protrusions 4 and 5 are alternately arranged at the center of the back of the shoe (that is, the left and right columnar protrusions 4 and 5 are slightly displaced from each other and formed between the columnar protrusions 4 and 5. The labyrinth is made into a labyrinth (zigzag)), and the grass is intricately entangled with the gap between the columnar protrusions 4 and 5, so that the shoe is strong in the front-rear direction, left-right direction, and diagonal direction. A grip force is born, and a suitable grip force can be obtained when walking in a complex direction such as a golf course (slope) in various directions and hitting a ball on such a slope. Further, when walking on a hard road surface such as asphalt, a jagged portion which is a tip portion of the columnar protrusions 4 and 5 is bent, so that an appropriate cushioning property is produced, and there is an effect of reducing the burden on the foot.
[0070]
  Furthermore, in the case of golf play or walking in the rain, the grooves 11 provided in the columnar protrusions 4 and 5 appropriately drain water, so that the grip power is excellent even on wet road surfaces.
[0071]
