When we are planning a long day in the backcountry searching for the goods, we trust the Dynafit Radical Alpine Touring Boot to keep us mobile and our feet happy. The 103. 5mm last, one of the widest on the market, keeps our feet comfortable while we stroll up cat tracks and eat sandwiches on ridges. On the cat track, the Hoji Lock walk mode lever and its 60deg range of motion enables us to stride comfortably. Meanwhile, the 110 flex and thermo-moldable liner allow us to drive our skis with confidence through varying backcountry conditions.
