<p>An athletic shoe system may include a substantially flat mid-sole portion extending from a metatarsal joint area to a mid-heel arch area, a toe portion tapering upwardly lengthwise from the metatarsal joint area to a front edge of the system at a first angle of 25-35 degrees and tapering upwardly widthwise from the metatarsal joint area to an area along an outer edge of the toe portion at a second angle of 29-31 degrees. The athletic shoe system also may include a heel portion tapering upwardly from the mid-heel arch area to a back edge of the system at an angle of 25-35 degrees. The substantially flat mid-sole portion may contact a surface when the system is in a stationary position. The toe portion and the heel portion may have substantially uniform curvature along a longitudinal axis of the system.</p> |
