Perfect cheap approach setup. I have a pair of skis with silvretta 404 bindings, a pair of full length skins, and a pair of kicker skins. everything is in excellent condition, including the skin glue. The skis are an older style straight skis. since the bindings are similar to how automatic crampons work, they will work with 99% of the boots out there with front and rear welts. that means ski boots and mountaineering boots with front and rear ledges.
Its something to note that these are the only silvretta 404‘s I‘ve ever seen that have resort require brakes. so no leashes are required. I have skied groomer blues at the resorts with these, and they‘ll work in a pinch.
