Excellent, versatile boot for the right ski-binding set up. I use mine with Fischer Rebound Crown Skis and Vole 3 pin - cable bindings. Without the cables they're great for general touring and kick & glide on a good surface. Add skins and the binding's heel lifts and they're comfortable for steep climbing. With the cables they perform very well downhill. I can ski just about anything on this combination, and love it. It's very easy to put the cables on after the uphill before going down. Not ideal for the really steep and deep, but doable on anything. And even reasonably comfortable for walking.
