Abstract: A snowshoe with binding suspended by tension straps secured to a frame is assembled from a generally U-shaped nose, and an aft section which can be a midsection and a tail. In one embodiment the nose has sufficient strength to resist inward pulling under tension to suspend the binding resiliently, without significant strength contribution from aft portions of the frame. The aft portion of the snowshoe includes traction elements, i.e. rows of teeth, positioned to engage into snow and ice. An important aspect of the invention is that the nose and aft sections are non-integral and very dissimilar in cross section, in a suspended-binding snowshoe.

Abstract: A molded or plastic composite snowshoe is formed of two assembled sections, in a way that imparts flexibility to the snowshoe, allowing some degree of torsional twisting or warping flexibility so that the snowshoe adapts to uneven terrain. In a principal embodiment the molded snowshoe is divided into forward and aft sections along a line slightly behind the nose area and near the pivot axis in the case of a pitch-pivoting binding. Joints between sections are in narrow rims at left and right, at opposed sides of a large central opening for the crampon/binding and boot. The joints are designed to securely hold the forward and aft molded sections together but to allow a degree of torsion between them when needed. Steel structural traction rails extend across the joints but are constructed and secured to the snowshoe sections in a manner that preserves the desired flexibility.
