发明名称 Circular snowshoe
摘要 A snowshoe is described with a highly mobile circular frame. A woven webbing extends across the frame with a binding attached to an upper surface thereof. The frame includes an inclined annular surface that faces inwardly and downwardly to enable an outer annular edge of the frame to bite into the snow for traction in rough terrain. The snowshoe, due to its circular nature, can be constructed nearly entirely of vehicle tire components.
