About Dynafit 04 Carbon Ski Boot: Hi, I’m Tim from Dynafit, here with the 04 Carbon. This is the lightest four-buckle boot on the market. Carbon fiber stringers down the side, stiff in this boot up laterally. Drives the ski edge to edge faster than most, while still remaining one of the lightest boots you can put on your feet. Why do you want a light boot that’s is really stiff laterally? Because you’ve got to get it up to the top first. When flipped in the ski mode this boot can perform downhill with the best of, but when flipped in the tour mode on the back you can walk right up the mountain with these, feels like ankle high hiking boot. So, it’s really two booth in one, because of your day is being two days in one, hard efforts getting all the way to the top of the mountain, and then pure performance on the downhill. Dynafit also has quick stepping inserts. These little wings of metal on the side of our holes absolutely lineup the Dynafit binding, so in deep snow or in awkward terrain where you’re putting your ski on, we call it “stepping in blind”. You click easily right into the Dynafit bindings. It’s a feature that only Dynafit boots have. And a feature that completes these carbon fibers p-backs ultra light wonder. It’s no secret we call this thing “the green machine”.
