Abstract
Abstract A heel plate arrangement for a cross-country ski boot includes a male member located at the rear of a cross-country ski boot, the forward-most edge of the member being connected to the boot and the rearward-most edge of the member being unobstructed. A female member is sized and shaped to cooperate with and receive the male member, the female member including a vertical slot which is open along the top and at least at the forward-most end. The slot is shaped and has sufficient height, length and width for providing a positive interlock between the male member and slot for restricting lateral movement of the rear portion of the ski boot when the male member is received in the slot.
