The stiff flexing and supportive Thraxis is the go-to boot for aggressive freeriding at the resort or deep in the backcountry. Three separate BOA® reels control three different zones on the boot to dial in precise fit, and new Endo™ 2.0 construction helps to retain the original boot flex for daily riding durability. When the terrain demands your full attention, the Thraxis helps you stay you laser focused and ready to drop
