Abstract
A motion-assist shoe having a force translator with a dynamic portion comprised of a resiliently deformable material and configured to bias a rearward portion of a sole portion of the shoe upward relative to a forward portion of the sole portion.
Claims18
A motion-assist shoe comprising:
- an upper;
- a sole portion coupled to the upper, the sole portion comprising a forward portion and a rearward portion;
- and
- a force translator comprising a base portion and a leg portion, the base portion and the leg portion coupled by a dynamic portion;
- wherein the base portion, the leg portion and the dynamic portion are unitary one with another;
- wherein the base portion is coupled to the sole portion;
- wherein the leg portion is configured to contact, and conform to, a shin of a user of the shoe;
- wherein the shoe comprises a stressed configuration and an unstressed configuration;
- wherein, in the stressed configuration, the base portion and the leg portion are aligned at a first angle relative to each other;
- wherein, in the unstressed configuration, the base portion and the leg portion are aligned at a second angle relative to each other, the second angle being different from the first angle;
- wherein the dynamic portion is configured to bias the shoe toward the unstressed configuration to thereby bias the rearward portion upward relative to the forward portion;
- and
- wherein the dynamic portion is comprised of a resiliently deformable material.

A motion-assist shoe comprising:
- an upper;
- a sole portion coupled to the upper, the sole portion comprising a forward portion and a rearward portion;
- and
- a force translator comprising a base portion and a leg portion, the base portion and the leg portion coupled by a dynamic portion;
- wherein the leg portion is configured to contact, and conform to, a leg above an ankle of a user of the shoe;
- wherein the shoe comprises a stressed configuration and an unstressed configuration;
- wherein, in the stressed configuration, the dynamic portion is resiliently elongated and the base portion and the leg portion are at a first angle relative to each other;
- wherein, in the unstressed configuration, the dynamic portion is not resiliently elongated and the base portion and the leg portion are at a second angle relative to each other, the second angle being different from the first angle;
- wherein the dynamic portion is configured to bias the shoe toward the unstressed configuration to thereby bias the rearward portion upward relative to the forward portion;
- wherein the rearward portion of the sole portion extends rearward beyond a rearward-most portion of the upper;
- and
- wherein the force translator extends from the sole portion at a position rearward of the rearward-most portion of the upper.
