The women's Rossignol Alley BOA® H4 Snowboard Boots deliver the support you need for progressive all-mountain riding. A BOA® Fit System offers a snug, precision fit with the turn of a dial. The H4 dial auto retracts for quick, on-the-fly adjustments. A stiff articulated cuff complements the smooth boot flex for the support to push and build your skills. Thermo-moldable liners keep your feet warm and let you get a custom fit to match your foot shape. Hidden lace guides minimize wear, while a rubber outsole extends durability and provides confident grip on and off the board.
