Abstract
A sole construction for use with a boating shoe or the like comprises an outsole having a multiplicity of wave-like incisions in a traction area. The incisions are each in the form of a flattened sine wave and extend generally transverse to the longitudinal axis of the sole. A plurality of straight incisions intersect the wave-like incisions and extend substantially parallel to the longitudinal axis of the sole. The sole may further include inner and outer traction areas in which a plurality of incisions intersect wave-like incisions extending parallel to the longitudinal axis of the shoe, with the straight incisions extending substantially transverse to the longitudinal axis.
