Abstract: Crampon and snowshoe combinations are disclosed, wherein the crampon or terrain-engaging cleat can be a traditional ice crampon used on a rigid and essentially unbending boot, or a soft boot cleat which engages only the front portion of the boot, forward of the heel, permitting boot flexing. The snowshoe has in a toe or ball area a registry plate configured to engage with the crampon, preferably between depending teeth or other structure of the crampon, and preferably with a self-centering feature as the crampon is lowered down onto the registry plate. Once the cleat or crampon is fully engaged down against the plate, it is substantially locked in position against relative shifting or rotation, and lifting of the boot off the back of the crampon is restricted by clips or straps, preferably flexible straps extending up from the registry plate and securable to brackets or hooks on the crampon device. Specific configurations of cleats or crampons are also disclosed, for use with or without snowshoes.

Abstract: A snowshoe has a metal heel cleat of one-piece construction, providing the dual functions of angularly disposed teeth which extend down from the snowshoe's deck to engage snowy or icy terrain, and rows of serrations extending upwardly through a membrane, to a position for contact with the bottom of the user's boot heel for high friction, gripping engagement when weight is placed on the heel. The heel cleat device has a base platform which is positioned between two deck membrane layers, a lower of which is penetrated by the terrain-engaging cleat teeth and the upper of which is penetrated by the smaller, upwardly facing serrations which engage with the boot heel.

Abstract: A snowshoe is configured to receive a boot-mounted crampon, such that the crampon teeth serve as the front and rear cleats for the snowshoe. Two openings are included in the snowshoe deck, at toe and heel, the toe harness assembly including a plate configured to receive the front portion of a crampon such that the crampon is inserted into the snowshoe with the toe tipped down, then the heel is rotated down to lock the crampon to the plate. A single strap is included to secure the boot to the harness at a location behind the ball of the foot. In a preferred embodiment, left and right portions of the tooth assembly near the toe of the crampon fit closely within a clearance at each side of the plate, so that as the crampon is placed into the plate the crampon becomes located and registered to a certain position, rigidly holding the crampon on the plate against rotation about a vertical axis.
