Abstract
A sole and heel construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced thin fins that extend transversely across the body. The fins are evenly spaced and uniform in width throughout. All fins are identical and are inclined relative to a horizontal plane such that any weight applied to the sole compresses the fins to trap air between adjacent fins to minimize mud build-up.
