The Xcel Drylock 3mm Round-Toe Boots have been updated with a sleeker design and reduced bulk. This 3-dimensional boot contours to the foot while minimizing excess rubber on the sole, providing a true board feel. The new Thermo Dry Inferno (TDI) interior and Channel Flex exterior make it extremely warm and comfortable. A Drylock Cuff opening prevents flushing, while the ergonomic strap keeps your heel locked in and relieves pressure from the instep. A heel strap also makes for easy pull-on.
