If you live for picking apart steep lines, dropping huge cliffs, and bombing through chunder, then the ThirtyTwo Men's Prime Snowboard Boot is for you. It features a Power Wrap Cage, Tongue Tension system, and a Performance backstay to make it ThirtyTwo's stiffest boot perfect for big mountain and backcountry riding when uncompromising support and response are crucial. When you tighten the laces, the Power Wrap Cage pulls together to provide uniform tightness and a superior fit. The Performance backstay channels energy for enhanced heel to toe response so you can make quick turns and adjustments in unforgiving terrain. The Tongue Tension System prevents heel lift, which reduces fatigue while also improving response. An articulating cuff prevents the shell from breaking down over the course of the season. The Level 3 Intuition liner is heat moldable to provide a custom fit, and a Level 3 footbed with Intuition and Evolution foams ensures all day comfort. System G2 gel cushioning protects your heels from harsh impacts and smooths out the ride. The outsole features Evolution foam to keep weight down and improve cushioning, along with strategically placed rubber pods so you don't sacrifice traction or durability.
