Abstract
A variable friction shoe includes a midsole and an outsole. The outsole includes at least a first high-friction surface and at least a first low-friction surface, wherein the first low-friction surface remains prominent if vertical ground reaction forces (GRFs) are low and wherein the high-friction surface is prominent in response to increasing GRFs.
Claims21
A variable friction shoe comprising:
- a midsole;
- and
- an outsole having at least a first high-friction surface and at least a first low-friction surface, wherein the first low-friction surface is prominent if vertical ground reaction forces (GRFs) are low and wherein the high-friction surface comes into contact with the ground in response to increasing vertical GRFs, wherein the high-friction surface includes means for preventing slipping during the stance phase of the gait.
A variable friction shoe comprising:
- a midsole;
- and
- an outsole having at least a first high-friction surface and at least a first low-friction surface, wherein the first low-friction surface is prominent during a swing phase of a gait and wherein the high-friction surface contacts the ground during a stance phase of the gait, wherein the high-friction surface includes tracks to prevent slipping when in contact with the ground.
