  • Figs. 1-9 show an insole, generally designated 100, according to the presently disclosed technology.
  • Figs. 1-9 show an insole designed for a right foot, and a corresponding or mirror-image insole can be designed for the left foot.
  • the insole is designed for non-high heel or flatter shoes, such as running shoes or women’s flats.
  • the insole can be incorporated into insoles for other types of shoes, such as high heel shoes.
  • the insole 100 can include a top surface 104, an opposing bottom surface 106, a rear end 108 (i.e., near the heel area of the insole) and an opposing front end 110 (i.e., near the forefoot area of the insole). At least a portion of the top surface 104 proximate the rear end 108 can be concave. At least a portion of the bottom surface 106 proximate the rear end 108 can be convex. However, the insole 100 can have other configurations, such as an entirely flat bottom surface 106.

  • the insole 100 can include means for turning or adjusting the cushioning, performance and/or flexibility thereof.
  • the means can be in the form of a plurality of spaced-apart holes 122 that extend through the insole 100 from the top surface 104 to and through the bottom surface 106.
  • the holes 122 can increase the force attenuation and/or force distribution capacity of the insole 100, thereby creating, adding or decreasing cushioning provided by the insole 100, flexibility to the insole 100, and/or creating a more comfortable insole for the user.
  • Flexibility is important for two reasons. First, flexibility allows the contour of the insert to flex and accommodate the shape of the foot, while distributing load more evenly, thereby reducing peak loads and enhancing comfort. Second, dynamic flexion of the insert provides cushioning and/or impact attenuation during walking and running. [0030]
  • the holes 122 can lower the elastic modulus of the insole and thereby make the insole more flexible or elastic than if the holes 122 were not included in the insole. Optionally, the holes 122 provide for the spatial redistribution of load.
  • At least one of the plurality of holes 122 can be located in and/or extend through the heel area 130 of the insole 100. Alternatively or additionally, at least one of the plurality of holes 122 can be located in the midfoot area 132 of the insole 100.
  • fewer holes 122 can be located in the midfoot area 132 than both or either the feel area 130 and the forefoot area 134.

  • the holes 122 are not necessarily arranged in rows, but arranged in an eccentric, non-random pattern. Certain prior art, such as U.S. Publication No.
  • 2013/0340288 describe random distributions of apertures.
  • the presently disclosed technology is not random. Instead, the presently disclosed technology includes specific size, shape and/or placement of holes 122 to achieve particular tuning, adjustment, performance and/or cushioning.
  • Adjacent holes 122 are not necessarily the same size. Instead, the size, shape and/or location of each of the holes 122 is dependent upon, at least in part, the desired level or amount of cushioning and/or performance incorporated into the insole 100. For example, two adjacent holes 122 can have a different size, shape and/or diameter. More particularly, a first one of the plurality of spaced-apart holes 122 can be larger than a second one of the plurality of spaced - apart holes 122.
  • the presently disclosed technology is not limited to the insole 100 having only two different categories, types, and/or sizes of the holes 122, as the insole 100 can include three or more different categories, types, and/or sizes of the holes 122.
  • the largest one of the plurality of spaced-apart holes 122 can have a diameter of approximately 3, 4 or more millimeters, and a smallest one of the plurality of spaced-apart holes 122 can have a diameter of approximately 1, 0.5 or less millimeters.
  • the size, shape and/or location of each of the holes 122 can be used to adjust, modify or fine tune (e.g., increase and/or decrease) the cushioning and/or performance provided by the insole 100.
  • the size, shape and pattern of the holes 122 shown in Figs. 1-9 contribute to or dictate the cushioning and/or performance capabilities provided by the insole
  • At least the radially outer-most holes 122 are arranged in a predetermined pattern around the insole 100 and spaced a predetermined distance inwardly from the outer contour or periphery of the insole.
  • At least some of the plurality of spaced-apart holes 122 are configured to form three distinct and spaced-apart circles of holes.
  • the circles of holes are optionally placed in locations or regions of greatest pressure on the insole 100 by the foot.
  • the eccentric ally- shaped solid line 146 that surrounds each of the three circles of holes surrounds a region in which the greatest average pressure is placed on the insole by the foot. Pressure outside of the eccentrically- shaped solid line 146 is (or generally) less than pressure at or inside the eccentrically- shaped solid line.
  • a first one of the circles, generally designated 136 is positioned at or near (e.g., beneath) the head of the first metatarsal of the user’s foot.
  • a second one of the circles, generally designated 138 is optionally positioned beneath the forefoot of the user’s foot.
  • a third one of the circles, generally designated 140 is optionally positioned beneath the heel of the user’s foot.
  • the second circle 138 is larger (e.g., includes more holes 122) than the third circle 140, which is larger than the first circle 136.
  • the second circle 138 has as a radius of at least four holes 122
  • the third circle 140 has a radius of at least three holes 122
  • the first circle 136 has a radius of at least two holes 122.
  • the holes 122 that form the three circles can be the same size, while the remaining holes 122 in the insole 100 are smaller.
  • the holes 122 can be arranged on or in the insole 100 to match a pressure diagram created when a user’s foot is placed on the ground.
  • the holes 122 can be located in the areas of the insole where the most weight or pressure is applied by the user’s foot.
  • smaller and/or fewer holes 122 are positioned proximate the arch than the forefoot and the heel.
  • the holes 122 positioned proximate the ball of the user’s foot are generally larger than the holes 122 positioned proximate the arch of the user’s foot. This is because, in at least certain shoes, it can be desirable to provide more cushioning to the balls of the user’s foot than the arch of the user’s foot.
  • the holes 122 extend across the width of the insole 100.
  • one or more of the holes 122 are located along a longitudinal axis A (e.g., equidistant from either lateral edge, as shown in Fig. 5) of the insole 100.
  • the plurality of holes 122 can be located in only a certain portion or portions of the insole 100, while another portion or portions of the insole 122 would not include any holes 122 or perforations.
  • the heel area of the insole 100 can include the plurality of holes 122, while the forefoot area can be void of any perforations or can include only smaller perforations for breathability purposes.

  • the size of the holes 122 is generally smaller than an insole having a higher durometer.
  • an insole having a higher durometer has holes 122 that are generally larger than an insole having a plate with a lower durometer. This is because less cushioning, performance and/or flexibility on account of the holes 122 is needed or desired for an insole with material or a plate (i.e., a component of certain types of insoles) having a lower durometer. Curvature and/or contour of a top surface 104 of the insole 100 can impact the size of the holes 122.

In another embodiment, the plurality of holes 122 can be in only three different sizes. In yet another embodiment, the plurality of holes 122 can be in four or more different sizes.
  • each or at least one of the plurality of holes 122 can have a different geometric shape, such as elliptical or rectangular (when viewed from above), depending upon the cushioning levels and traits desired for the insole 122.
  • one or more or each of the plurality of holes 122 can have a cone or frusto-conical shape (see, e.g., Fig. 11) when viewed from the size or in elevation.
  • the insole 100 can be designed and/or manufactured separately from a shoe to which the insole 100 is to be used with. The insole 100 can be inserted or slipped into the shoe for use.
