A snow board binding designed to facilitate "soft boot" skiing techniques, incorporating a means for form fitting of the ski boot to the binding by providing a natural hinge structure as a means of side support pieces and also comprising a highback contoured to approximate the shape of a typical ski boot ankle and calf section and a heel piece contoured to approximate the shape of a typical ski boot heel section. The ski boot is located within the confines of the binding by means of both instep and heel straps.
