Definitions

  • An article of footwear having an upper secured to an outsole in combination having three toe pockets, the first toe pocket having a configuration to separately receive within a big toe of a wearer, and the second toe pocket having a configuration to separately receive within a second toe of the wearer, and the third toe pocket having a configuration to receive within the remaining third toe, fourth toe and fifth toe of the wearer.
  • footwear having an upper and an outsole in combination providing a toe cap having a structure which receives the five toes of the foot as a group.
  • footwear having a toe cap has the disadvantage of requiring all five toes of the foot to move as a group within the footwear even though the big toe is anatomically structured to move independent of the four other toes. This disadvantage has been addressed by a variety of different forms of footwear.
  • footwear having five toe pockets each having a configuration to correspondingly receive one each of five toes allows independent articulation of each toe within a corresponding toe pocket as described in United States Patent No. 7,805,860 .
  • footwear having five toe pockets may have the disadvantage of forcing the toes to move independently of each other, even though the four most lateral toes of the human foot share common musculature and tendons and generally move together as one group.
  • footwear having four toe pockets with the most medial three toe pockets correspondingly structured to receive one each of the big toe and the adjacent two toes and the most lateral of the four toe pockets structured to receive the most lateral two toes of the human as one group is shown in United States Design Patent No. D639,535 ; however, this structure may not advantage movement of the three most lateral toes of the human foot as one group consistent with the shared musculature and tendons.
  • footwear having two toe pockets with the most medial first toe pocket correspondingly structured to be received the big toe and the second toe pocket correspondingly structured to receive the remaining four toes of the human foot as group is shown by United States Patent 7,971,374 .
  • the four toes of the human foot located within one toe pocket may be disadvantaged by a loss of prehensility, or loss of grasp between the big toe and the second toe.
  • document WO 2005/074737 A1 discloses an article of footwear (10) for sand sports that includes an outsole (24) and an upper (22) secured to the outsole.
  • the upper has a first toe pocket (32) configured to receive a big toe of a user and a second toe pocket (34) configured to receive at least some of the remaining toes of the user.
  • a wrap extends (38) around a midfoot portion of the outsole and the upper, and around a heel portion of the upper.
  • a plurality of cleats (60) may be secured to a lower surface of the outsole.
  • a five toe shoe comprises: an upper which is made out of a moisture-permeable fiber material and has a toe area to encase each toe separately according to the shape; an insole which is made out of a porous material; a midsole which is placed underneath the insole and has a metal mesh to allow water in the shoe to exit therethrough; and an outsole which has a drain formed in coincidence with the metal mesh of the midsole and a toe area for each toe separately according to the shape, being connected to the toe area of the upper in a one-to-one correspondence therebetween.
  • five toe shoes may contribute greatly to foot health of wearers by improving breathability as water from the inside of the shoes drains naturally by gravity via the insole, midsole and outsole and evaporates quickly through the upper at the same time, and offer more convenience in activities with the toe area encasing each toe separately according to the shape.
  • the invention relates to an article of footwear as specified in appended independent claim 1. Preferred embodiments of the invention are disclosed in the dependent claims.
  • the footwear (1) has a medial side (9) (the inner side) and a lateral side (10) (or outer side).
  • the portions (4)(7)(8) are not intended to demarcate precise areas of the footwear (1), but are intended to represent general areas of the footwear (1) that provide reference for the following description.
  • the footwear (1) as shown in Figure 1 is disposed substantially horizontally with the lateral side (10) in the foreground, as it would be positioned on a horizontal support surface (not shown) when worn by a wearer (81). However, it is to be appreciated that the footwear (1) need not be limited to such an orientation.
  • the human foot (6) is shown in Figure 1 and Figure 2 by broken line inside of the footwear (1) and parts thereof identified by the use of numerical indicators at the end of leader lines rendered in broken line.
  • the footwear (1) includes an upper (2).
  • the upper (2) refers to the part or parts of the footwear (1) that cover the toes (12), the top of the foot (13), the sides of the foot (14), and the back of the heel (15).
  • the upper (2) can be cut from a single piece, or a plurality of pieces of material.
  • the heel portion (8) of the upper (2) terminates in a top line (16) which can surround the ankle (17) of the (81) (as shown in the example of Figure 1 ) or may extend further up the leg (18) of the wearer (81) depending upon the embodiment.
  • a collar (19) can be joined to the top line (16) of the upper (2).
  • the collar (19) can be made of a stretchable material which conforms to the wearer's (81) foot (6), ankle (17) or leg (18).
  • the collar (19) can be releasably adjustable to allow the amount of open area (20) defined by the periphery of the collar (19) (as shown in the example of Figure 2 ) to be altered or adjusted by the wearer (81).
  • the collar (19) can have a passage (21) configured to receive a cord (22) or drawstring.
  • the drawstring (22) can have adjustable length such that amount of open area (20) defined by the collar (19) can be selected by the wearer (81) by adjusting and fixing the length of the drawstring (22).
  • the length of the drawstring (22) can be fixed by a drawstring fastener (23) which can take any of a wide variety of forms including for example, tied ends of the drawstring (22), or a sliding spring loaded cord clamp (24) (as shown in the examples of Figures 1 and 2 ).
  • the upper (2) can be secured by the periphery to an outsole (3).
  • the outsole (3) (or sole) refers to the part of the footwear (1) that comes into contact with the support surface during normal use.
  • the outsole (3) can be made from one piece from a plurality of pieces.
  • the heel portion (8) of outsole (3) may be made of a different material than the midfoot portion (7) or forefoot portion (5).
  • the outsole (3) can be secured to the upper (2) by an adhesive, stitching, or other suitable securement means.
  • the outsole (3) can be made from natural materials such as leather or natural rubber, or from synthetic materials such as styrene butadiene rubber, nitrile-butdiene rubber, polyvinyl chloride, polyurethane, neoprene, polyether, polyester, or the like, or combinations thereof, whether as a solid material or as a foam, thermofoam, closed cell foam, or layers or combinations thereof.
  • a raised tread pattern (25) demarcated by tread grooves (26) can extend over substantially the whole of the bottom of the outsole (3). While the invention is not limited to any particular raised tread pattern (25) and particular embodiments may be without any raised tread pattern (25), the raised tread pattern (25) can take the form of a crosshatch (27) (as shown in the example of Figure 4 ).
  • the outsole (3) can further provide one or more flex groove(s) (28) which can extend partially across or extend substantially across the entire width of the outsole (3) between the medial side (9) and lateral side (10) of the footwear (1).
  • the flex groove (28) can be generally aligned with the joint line (29) of the medial metatarsal phalanges of the foot (6) (as shown in the example of Figure 1 ) to enhance flexibility of the outsole (3) at a location which aids in natural foot motion.
  • the upper (1) secured to the outsole (3) in combination can have three toe pockets (29)(30)(31).
  • the first toe pocket (29) has a configuration to separately receive inside a first toe (32) of the wearer (81).
  • the first toe (32) being the most medial toe of the foot (6) (also referred to as the "big toe” or "hallux").
  • the second toe pocket (30) has a configuration to separately receive inside a second toe (33) of the wearer (81).
  • the second toe (33) being the located next to the first toe (32) (also referred to as the "long toe”).
  • the third toe pocket (31) has a configuration to receive inside the remaining third toe (34), fourth toe (35) and fifth toe (36) (also referred to as the "little toe” and being most distal from the first toe (32)).
  • the big toe (31) is primarily flexed by the flexor hallucis longus muscle, located in the deep posterior of the lower leg (18), via the flexor hallucis longus tendon. Additional flexion control is provided by the flexor hallucis brevis. It is extended by the abductor hallucis muscle and the adductor hallucis muscle. The big toe (31) can be moved independently of the remaining or other toes (33)(34)(35)(36).
  • a separate first toe pocket (29) allows the first toe (32) (the "big toe") to be separately received within the footwear (1) to maintain movement in a toe which naturally moves independently of the other toes (33)(34)(35)(36).
  • the second toe (33), third toe (34), fourth toe (35) and fifth toe (36) the flexor digitorum brevis muscle and the extensor digitorum brevis muscle and the flexor tendons are shared, making these toes (33)(34)(35)(36) generally move as one unit. However, some prehensility, or grasping capability, in these toes still exists.
  • the upper (2) of at least one of the three toe pockets (29)(30)(31) can include a toe top portion (37)(38)(39) in combination with a toe side portion (40)(41)(42).
  • the toe side portions (40)(41)(42) can be secured to the outsole (3) and extend upwardly to correspondingly connect to the toe top portions (37)(38)(39).
  • the first toe pocket (29) can have a first toe top portion (37) configured to generally overlay the top (43) of the first toe (32) received inside of the first toe pocket (29) and a first toe side portion (40) which surrounds the medial side (44), front side (45) and lateral side (46) of the first toe pocket (29).
  • the second toe pocket (30) can have a second top toe portion (38) of the upper (2) which generally overlays the top (47) of the second toe (33) received inside of the second toe pocket (30) and a corresponding second toe side portion (41) that surrounds the medial side (48), front side (49) and lateral side (50) of the second toe pocket (30).
  • the third toe pocket (31) can have a third top toe portion (51) of the upper (2) which generally overlays the top (52) of the third toe (34), fourth toe (35), and fifth toe (36) received inside of the third toe pocket (31) and a corresponding third toe side portion (42) that surrounds the medial side (53), front side (54) and lateral side (55) of the third toe pocket (31).
  • the outsole (3) does not need to extend substantially upward and does not need to overlay any one of the toes (32)(33)(34)(35)(36).
  • the outsole (3) can extend upward at the front well below or reside at about the midline of each of the toes (32)(33)(34)(35)(36) with the toe side portions (40)(41)(42) of the upper (2) extending upward to join the corresponding toe top portions (37)(38)(39).
  • This structure allows each of toes (32)(33)(34)(35)(36) to move forward in the footwear (11) without the toe end (56) being forcibly urged against the inside of the outsole (3). Rather, the corresponding side toe portion (40)(41)(42) when made from a flexible textile material can stretchably engage one or more toe ends (56) reducing force applied to the toe end (56) without substantial loss of force of the toe downwardly against the outsole (3). This structure can avoid or reduce injury to the toe end(s) (56) or the corresponding toe nail(s) (57).
  • one or more of the three toe pockets (29)(30)(31) can further include one or more flex elements (58) disposed in the flexible textile material of one or more of the top toe portions (37)(38)(39) of the upper (2) which can extend partially across or extend substantially across the entire width of the top toe portion (37)(38)(39) between the medial side and lateral side of the each corresponding toe pockets (29)(30)(31).
  • the one or more flex elements (58) allows the top toe portion (37)(38)(39) of the upper (2) to flex more readily upon flexure of the outsole (3).
