Abstract: A ski shoe harness includes a sole, a receiver, and a heel strap. The sole includes a binding mechanism adapted to engage a binding system of a ski. The sole and the receiver are attached and define a space to receive the front portion of a shoe. The heel strap, attached to the receiver, wraps around the rear portion of the shoe, interlocking the ski shoe harness with the shoe. Further, the heel strap includes an adjustment mechanism. Using the ski shoe harness of the present invention, non-ski shoes and boots of a various designs and sizes may be used to share and utilize skis having common cross-country binding systems.
