Claims16
A prosthetic foot comprising:
- a sleeve having opposed lateral sidewalls extending between an anterior sidewall and a posterior sidewall;
- a forefoot member having a forefoot member upper end received within the sleeve and a portion of the forefoot member extending downwardly out of the sleeve;
- a heel member having a heel member upper end received within the sleeve and a portion of the heel member extending downwardly out of the sleeve;
- and
- a pin passing through a lateral sidewall and contacting the forefoot member and heel member in such a way that the pin prevents the forefoot member and heel member from falling out of the sleeve
- wherein the forefoot member and heel member together define a groove and the pin includes a pointed end that fits in within the groove, thereby preventing the forefoot member and heel member from falling out of the sleeve.

A prosthetic foot comprising:
- a sleeve having opposed lateral sidewalls extending between an anterior sidewall and a posterior sidewall;
- a forefoot member having a forefoot member upper end received within the sleeve, the forefoot member extending downwardly out of the sleeve through a curved forefoot section outside the sleeve to a toe end forward the curved forefoot section;
- a heel member having a heel member upper end received within the sleeve, the heel member extending downwardly out of the sleeve through a curved heel section outside the sleeve to a heel end rearward the curved heel section;
- and
- a pin passing through a lateral sidewall and directly contacting the forefoot member and heel member in such a way that the pin prevents the forefoot member and heel member from falling out of the sleeve;
- wherein the heel member upper end and forefoot member upper end can translate vertically within the sleeve independently of one another.

A prosthetic foot comprising:
- a sleeve;
- a forefoot member having a forefoot member upper end received within the sleeve, a portion of the forefoot member extending downwardly out of the sleeve;
- a heel member having a heel member upper end received within the sleeve, a portion of the heel member extending downwardly out of the sleeve;
- a compressible member positioned above the forefoot member upper end and heel member upper end, the compressible member being in compressible contact with the forefoot member upper end and heel member upper end;
- a pin passing through the sleeve and contacting the forefoot member and heel member in such a way that the pin prevents the forefoot member and heel member from falling out of the sleeve;
- and
- a pin securing member extending around the sleeve and pressing the pin inwardly through the sleeve against the forefoot member and heel member;
- wherein the heel member upper end and forefoot member upper end can translate vertically within the sleeve independently of one another;
- wherein the forefoot member and heel member together define a groove and the pin includes a pointed end that fits in within the groove, thereby preventing the forefoot member and heel member from falling out of the sleeve.
