Abstract: An apparatus, system, and method are disclosed for a collapsing approach ski for maneuvering over terrain in a climbing and sliding fashion, with a traction component operative below the sliding surface on the underside of the ski to facilitate climbing uphill without substantially interfering with sliding downhill. It combines the advantages of a snowshoe, including a large surface area, a toe cleat that claws into the terrain and a lifting of the front tip with each step, with the advantages of an approach ski, including a fibrous skin for added traction climbing uphill and an ability to slide down hill. A stretchable portion in the skin adjacent to a hinge in the ski permits the ski to be compactly collapsed without removing the skin, for easy packing and storage while not in use. For climbing up a steep incline, a removable fixed cleat provides added traction, and a heel riser reduces the strain on the lower leg and Achilles tendon region of the skier.
