Abstract

There is provided an insole for a sport footwear, the insole comprises: a forefoot portion comprising an incliner for inclining a foot of a wearer towards an outer side of the insole, a midfoot portion having an arch extending from an underside of the insole, and a rearfoot portion comprising an incliner for inclining the foot of the wearer towards the outer side of the insole. Such an insole can be effective for maintaining a linear motion of the knee of the user. Moreover such an insole can be effective for maintaining the foot of the person inclined outwardly. Thus, the body weight of the person can also be shifted outwardly, which improves balance.

Claims

1. An insole for a sport footwear, the insole comprising:

a forefoot portion comprising a forefoot wedge for inclining a foot of a wearer towards an outer side of the insole, the forefoot portion having a proximal hallux portion, a distal hallux portion and a front end, the front end dimensioned to be placed beneath a distal end of toes of the wearer wearing the insole;

a midfoot portion having a longitudinal arch comprised within an underside of the insole, the arch defining a recess on the underside of the insole, the recess extending laterally from an inner side of the insole to a second location intermediate the inner side and the outer side of the insole, the recess being dimensioned to receive a protruding arch of the sport footwear; and

a rearfoot portion comprising a rearfoot wedge for inclining the foot of the wearer towards the outer side of the insole, the rearfoot portion having a front rearfoot portion and a rearward rearfoot portion, the front rearfoot portion being in-between the midfoot portion and the rearward rearfoot portion, the front rearfoot portion being tapered from the inner side of the insole to the outer side of the insole and from a front end of the front rearfoot portion towards a rear end of the insole, the rearward rearfoot portion being tapered from the inner side of the insole to the outer side of the insole and from the rear end of the insole towards the front rearfoot portion;

wherein a first thickness of the proximal hallux portion of the forefoot portion is greater than a second thickness of the distal hallux portion of the forefoot portion and a difference between the first thickness and the second thickness is configured to incline the forefoot portion towards the front end to promote linear movement of a knee of the wearer.

2. The insole of claim 1, wherein the forefoot wedge of the forefoot portion comprises an at least partially tapered portion from the inner side of the insole towards the outer side of the insole.

3. The insole of claim 2, wherein the at least partially tapered portion of the forefoot portion is spaced apart from a front end of the insole.

4. The insole of claim 2, wherein the at least partially tapered portion extends from the inner side of the insole to a location intermediate the inner side and the outer side.

5. The insole of claim 2, wherein the forefoot wedge is tapered towards the front end of the insole.

6. The insole of claim 1, wherein a first metatarsal height of a first metatarsal portion of the midfoot portion is greater than a fifth metatarsal height of a fifth metatarsal portion of the midfoot portion.

7. The insole of claim 6, wherein a midfoot height of the inner side of the midfoot portion is greater than a forefoot height of the inner side of the forefoot portion.

8. An insole for a sport footwear, the insole comprising:

a forefoot portion comprising a forefoot wedge for promoting supination of a foot of a wearer, the forefoot portion having a proximal hallux portion, a distal hallux portion and a front end, the front end dimensioned to be placed beneath a distal end of toes of the wearer wearing the insole;

a midfoot portion having a longitudinal arch comprised within an underside of the insole, the arch defining a recess adapted to receive a protruding arch of the sport footwear; and

a rearfoot portion comprising a rearfoot wedge for promoting supination of the foot of the wearer, the rearfoot portion having a front rearfoot portion and a rearward rearfoot portion, the front rearfoot portion being in-between the midfoot portion and the rearward rearfoot portion, the front rearfoot portion being tapered from the inner side of the insole to the outer side of the insole and from a front end of the front rearfoot portion towards a rear end of the insole, the rearward rearfoot portion being tapered from the inner side of the insole to the outer side of the insole and from the rear end of the insole towards the front rearfoot portion;

wherein a first thickness of the proximal hallux portion of the forefoot portion is greater than a second thickness of the distal hallux portion of the forefoot portion and a difference between the first thickness and the second thickness is configured to incline the forefoot portion towards the front end to promote linear movement of a knee of the wearer.

9. An insole for an ice skate, the insole comprising:

a forefoot portion comprising a forefoot wedge for inclining a foot of a wearer towards an outer side of the insole, the forefoot portion having a proximal hallux portion, a distal hallux portion and a front end, wherein a the front end of the forefoot portion is dimensioned to be placed beneath a distal end of toes of the wearer wearing the insole;

a midfoot portion having a longitudinal arch comprised within an underside of the insole, the arch defining a recess on the underside of the insole, the recess being dimensioned to receive a protruding arch of the ice skate; and

a rearfoot portion comprising a rearfoot wedge for inclining the foot of the wearer towards the outer side of the insole, the rearfoot portion having a front rearfoot portion and a rearward rearfoot portion, the front rearfoot portion being in-between the midfoot portion and the rearward rearfoot portion, the front rearfoot portion being tapered from an inner side of the insole to the outer side of the insole and from a front end of the front rearfoot portion towards a rear end of the insole, the rearward rearfoot portion being tapered from the inner side of the insole to the outer side of the insole and from the rear end of the insole towards the front rearfoot portion,

wherein a first thickness of the proximal hallux portion of the forefoot portion at the inner side at a location spaced apart from the front end is greater than a second thickness of the distal hallux portion of the forefoot portion and a difference between the first thickness and the second thickness is configured to incline the forefoot portion towards the front end to promote linear movement of a knee of the wearer.

10. The insole of claim 9, wherein the forefoot wedge of the forefoot portion comprises an at least partially tapered portion from the inner side of the insole towards the outer side of the insole.
