A snowshoe binding engages the sole of the user's boot in a region between the arch and the widest part of the sole, gripping the sole laterally and sufficiently firmly that the boot will not pull out of the binding during use of the snowshoe, even in the absence of a heel strap. The arch area of the boot typically is narrower in width than the ball of the foot, providing a rearwardly tapering region for positive engagement against pulling back of the boot in the binding. By engaging the boot at the sole, the binding can put pressure on the boot not felt by the user. In one form the sole engaging binding device has a width adjustment with a sliding element, and the firmly clamping sole engagement preferably is accomplished with a cam that engages when a strap is tightened. An efficient buckle and strap are also disclosed.

Snowshoe binding without heel strap

A snowshoe of the type with a peripheral frame formed of metal tubing and a stretched and suspended deck connected to the frame has different regions of the frame partially flattened into an approximate elliptical cross section, the major dimensions of the ellipses being in different planes in different regions of the frame. Most of the nose loop at the front end of the snowshoe frame is elongated in cross section within the plane of the nose loop, while the sides of the frame, aft of the binding suspension, may be elongated in a generally vertical plane. The orientation of these elongated cross sections in specific regions affords more strength to the frame where needed, enabling the frame to be produced of lighter material. In addition, selected local regions of the frame can be swaged to form recesses at desired sides of the frame to receive and hold the binding suspension bands or deck connecting material that wraps over the frame. Preferably the frame is formed of malleable but heat-treatable metal such as aluminum 7075 or 6061.
