The fluffy lining is soft and offers a warm and comfortable entry into the boot.Lacing systemThe BOA® Fit System with Dual Zone and Coiler™ technology features two independent lace zones, including dedicated heel hold, that can be simultaneously adjusted at the upper and lower sections of the boot through the dial.
