ABSTRACT:
An athletic shoe which has a light-weight and readily flexible sole construction including shock absorbing portions in the heel and forefoot areas of the sole having different shock absorbing porperties with the shock absorbing portion in the heel area having a shock absorbing property greater than that in the forefoot area. Flexible nubs are included on the sole for traction and cushioning purposes where the spacing between nubs in heavy load bearing areas of the sole is less than the spacing between nubs in light load bearing areas of the sole. The nubs are positioned to facilitate flexing of the sole along normal breaklines corresponding to the joints of the foot of a wearer. The heel portion of the sole may include a cut out forming in part a vertically extending deflection rib surrounding a shock absorbing portion to further enhance shock absorbing, cushioning and propulsion properties.
