The Rossignol Crank Boa H4 snowboard boots are built to provide the support and precision needed for advanced all-mountain riding. Featuring the Boa Fit System, these boots offer a secure, customizable fit at the turn of a dial, while the H4 Coiler automatically retracts for quick adjustments on the fly. A stiff articulated cuff works in harmony with the smooth flex to give you the support needed to progress your skills. The True Form thermo-moldable liner delivers a custom fit tailored to your foot, reduces play, improves precision, minimizes fatigue, and keeps your feet warm. Additional features include hidden lace guides to prevent wear, a durable rubber outsole for traction on and off the board, and an EVA midsole for added comfort and shock absorption.
