A totally new concept developed from scratch by Amer co-brand Salomon, the Shift toe piece changes from a low profile conventional toe in ski mode to a fully "pinned" tech toe for skinning. The binding feels like a lighter, lower Warden 13 going downhill, then lets you engage your tech-toed boot to smoothly skin uphill. With a weight of 865 grams per binding, the Shift is a remarkable advance in both skiing and touring performance relative to frame AT bindings, and a very viable choice for those who want to ski lift-served terrain and true backcountry on a single setup.
