Abstract
A shoe insole comprising a cut out that follows the projection of the metatarsal area, said insole made out of a rigid material, and with a first predetermined thickness so that a user's weight is transmitted to the user's toes and calcaneal anterior area while minimizing the weight applied to the metatarsal area.

A shoe insole configured to be worn by a wearer, the insole comprising:
- a forefoot section;
- a midfoot section;
- and
- a hindfoot section;
- wherein said insole is made of a rigid material and includes a first predetermined thickness;
- wherein said forefoot section comprises a bay that extends directly from a lateral edge of the forefoot section towards a medial portion of the forefoot section and extends through the entire thickness of the insole, removing a portion of said insole that is configured to underlie the wearer's second through fifth proximal phalanges and a forward portion of the wearer's second through fifth metatarsal bones;
- wherein said forefoot section further comprises a toe end portion directly adjacent to the bay, the toe end portion having a peninsular shape that is configured to underlie the wearer's first through fifth distal phalanges, wherein the toe end portion includes a plurality of rounded portions configured to respectively correspond to each of the wearer's first through fifth distal phalanges;
- wherein, when the insole is used, the user's weight is transmitted to the user's distal phalanges and the user's anterior calcaneal area, while minimizing the weight applied to the user's metatarsal area.
