Abstract
Abstract An exercise shoe for wear on a human foot during simulated jogging comprises a foot support platform characterized by a substantially planar foot support surface, a sharper-than-circular curved bottom surface for providing forward-breaking and backward-breaking motions during simulated jogging and means for attaching the platform to a foot. In a preferred embodiment, the bottom surface is substantially hyperbolic.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
63 words
An exercise shoe for wear on a human foot during simulated jogging, comprising a foot support platform characterized by a substantially planar foot support surface; a bottom surface having a sharper than circular center portion smoothly leading to substantially linear regions extending to each end, for providing forward-breaking and backward-breaking motions during simulated jogging, and means for attaching said platform to such foot.
Claim 2
Dependent Claim
63 words
