  • the wedge 196 may be further tapered towards the front end 164 of the insole and its front edge 212 .
  • the combination of the tapering of the wedge 196 towards the front end 164 and outer side 140 provides a gradual decrease of the thickness of the forefoot portion 108 towards the front and outer sides of the insole 100 .
  • the wedge 196 is integrally formed with the underside 204 of the insole 100 .
  • the molding may include a recess corresponding to the wedge 196 so that the insole member formed from the molding includes the wedge 196 .
  • the wedge 196 is connected to the underside 204 of the insole 100 .
  • the wedge 196 and the insole 100 may be discrete members being connected together.
  • the arch 148 is shown to extend from an underside 204 of the insole.
  • the position of the arch 148 corresponds to an arch of the wearer's foot.
  • the arch 148 can define a recess 228 in the underside of the insole 100 .
  • the recess 228 may extend from the inner side 132 towards the outer side 140 to a second location 236 intermediate the inner side 132 and the outer side 140 .
  • the recess 228 may be shaped according to a midfoot protruding arch of the sport footwear in which the insole 100 is to be inserted.
  • the midfoot protruding arch when inserted into the sport footwear and disposed over the bottom interior surface thereof, the midfoot protruding arch may be received within the recess 228 and at least the arch 148 of the midfoot portion 116 is supported by the protruding arch of the footwear.
  • the arch 148 causes a portion of the top side 156 of the midfoot portion 116 to be raised with respect to the forefoot portion 108 and rearfoot portion 124 .
  • a region of the midfoot portion 116 proximate the inner side 132 of the insole 100 can have a greater height above the underlying surface than the height above the underlying surface of a region of the midfoot portion 116 proximate the outer side 140 of the insole 100 .
  • the height of the topside 156 of the midfoot portion 116 relative to the underlying surface may be gradually decreasing in a direction from the inner side 132 towards the outer side 140 .
  • the gradually decreasing height of the topside 156 promotes outwardly inclination and/or supination of the wearer's foot.
  • a height of a first metatarsal portion of the midfoot portion 116 is greater than a height of a fifth metatarsal portion of the midfoot portion 116 .
  • a height of a first metatarsal portion, a height of a second metatarsal portion, and a thickness of a third metatarsal portion of the midfoot portion are each greater than a height of the fifth metatarsal portion of the midfoot portion 116 .
  • a height of a region of the topside 156 of the insole 100 proximate the inner side 132 of the midfoot portion 116 is greater than the height of a region of the topside 156 of the insole 100 proximate the inner side 132 of the forefoot portion 108 .
  • this difference in height between the inner side 132 of the forefoot portion 108 and the inner side of the midfoot portion 116 causes the wearer's foot to also be slightly inclined towards the front end 164 .
  • the arch 148 may cause the midfoot portion 116 to have an upward inclination of about 2° to about 9° along a path from an outer side 140 of the insole to the inner side 132 of the insole and perpendicular to a lengthwise axis 106 . That is, within a plane located in the midfoot portion 116 and perpendicular to the lengthwise axis 106 , the upper surface of the midfoot portion 116 has the upward inclination of about 2° to about 9°.
  • the midfoot portion 116 may have an upward inclination of about 4° to about 8° along the path from an outer side 140 of the insole to the inner side 132 of the insole and perpendicular to a lengthwise axis 106 .
  • the midfoot portion 116 may have an upward inclination of about 6° to about 7° along the path from an outer side 140 of the insole to the inner side 132 of the insole and perpendicular to a lengthwise axis 106 .
  • the inclined midfoot portion 116 may cause an about 2° to about 9° supination of a foot of a wearer placed above the insole 100 .
  • the midfoot portion 116 may cause an about 4° to about 8° of the foot of the wearer.
  • the midfoot portion 116 may cause an about 6° to about 7° of the foot of the wearer.
  • the second incliner of the rearfoot portion 124 includes an at least partially tapered portion being tapered from the inner side 132 of the insole 100 towards an outer side 140 of the insole 100 .
  • the thickness of a region of the rearfoot portion 124 near its inner side 132 is greater than the thickness of a region of the rearfoot portion 124 near its outer side 140 .
  • FIG. 5 therein illustrated a rear elevation view of the insole 100 according to various exemplary embodiments.
  • the second incliner of the rearfoot portion 124 causes a thickness of a region of the rearfoot portion 124 near its inner side 132 to be greater than thickness of a region of the rearfoot portion 124 near its outer side 140 .
  • At least a region of the tapered portion of the rearfoot portion 124 proximate the rear end 244 of the insole extends continuously from the inner side 132 to the outer side 140 .
  • the at least partially tapered portion of the rearfoot portion 124 extends in a side-to-side direction from the inner side 132 of the insole 100 to a location intermediate the inner side 132 and the outerside 140 . Accordingly, a thickness of the rearfoot portion 124 gradually decreases from the inner side 132 to the location intermediate the inner side 132 and the outer side 140 corresponding to an edge of the at least partially tapered portion of the second incliner of the rearfoot portion 124 .
  • FIG. 6 therein illustrated is a side elevation view of an outer side of the insole 100 according to various exemplary embodiments.
  • at least a region of the tapered portion of the rearfoot portion 124 proximate the outer side 140 of the insole may be further tapered from the rear end 244 of the insole 100 towards the front end 164 of the insole 100 .
  • the forward tapering of the outer side 140 of the second incliner 252 of the rearfoot portion 124 promotes the forward inclination of the outside of the foot, which further promotes linear movement of the wearer's knee.
  • a region of the rearfoot portion 124 proximate the inner side 132 of the insole 100 and extending from the rear end 244 to the midfoot portion 116 may have a substantially constant thickness.
  • a thickness of a region of the rearfoot portion 124 proximate the rear end 244 of the insole 100 is greater than a hallux portion of the forefoot portion 108 .
  • this region of the rearfoot portion 124 corresponds to a calcaneus of the wearer's foot. Accordingly, when the insole 100 is disposed on an inner bottom surface of a footwear item and a wearer's foot is positioned over the insole 100 , the difference in thickness behind the region of the rearfoot portion 124 and the hallux portion of the forefoot portion 108 promotes the forward inclination of the outside of the foot, which further promotes linear movement of the wearer's knee.
  • the incliner of the rearfoot portion 124 includes a second wedge provided on an underside 204 of the insole 100 proximate to an inner side of the insole 100 .
  • the second wedge may be tapered from the inner side 132 of the insole 100 towards the outer side 140 .
  • the second wedge of the second incliner of the rearfoot portion is integrally formed with the underside 204 of the insole 100 .
  • the molding may include a second recess corresponding to the second wedge so that the insole member formed from the molding includes the second wedge of the incliner of the rearfoot portion 124 .
  • the second wedge is connected to the underside 204 of the insole 100 .
  • the second wedge and the insole 100 may be discrete members being connected together.
  • FIGS. 7, 8 and 9 illustrate an elevation view of an inner side of an insole placed in an upside-down orientation, an elevation view of an outer side of an insole placed in an upside-down orientation and a perspective view of an insole according to various exemplary embodiments.
  • the insole can be adapted for specific types of sports footwear.
  • the insole 100 is for sport footwear that is an ice skate, such as for figure skating, hockey, or speed skating.
  • the insole 100 is for sport footwear that is an ice hockey skate.
  • the insole 100 is for sport footwear that is a roller skate.
  • the insole 100 is for sport footwear that is a boot for downhill skiing.
  • the insole 100 is for sport footwear that is a boot for cross-country skiing.
  • the insole 100 is for sport footwear that is a shoe for cycling.
  • the insole 100 is for sport footwear that is a shoe for golfing.
