Packed with modern technology, the Atomic Hawx Ultra XTD 130 Boa GW Boot really impressed us with its versatility. The BOA fit system in conjunction with 2 aluminum buckles allow us to lock in the fit at the resort and loosen it on the uphill. The reliable Free/Lock walk mode lever stays where we want it so that we can trust the 130 flex on the downhill and stride confidently on the skin track.
