Jumping between rowdy pow days at the resort and quiet dawn patrols in the backcountry is a more common way than ever to spend a ski season. The major players are wising up to this shift in attitude, introducing boots and boards that match your unwillingness to commit exclusively to a season spent in-bounds or out.

Three lightweight, micro-adjustable aluminum buckles and a rugged power strap let you lock down a completely secure fit before you hammer out a big line, and at the end of the day, you can thank the QST Pro's EndoFit tongue for keeping the boot removing drama to a minimum, and its waterproof gusset for keeping your feet dry.
