Xcel Drylock Surf Boot Description Engineered for advanced 3D warmth and comfort, the updated Xcel Drylock Boot features a sleeker design with reduced bulk while maintaining premium cold water performance. This 3-dimensional boot contours naturally to the foot while minimizing excess rubber on the sole, delivering a true board feel with improved sensitivity and control. The Thermo Dry Inferno (TDI) interior combined with the flexible Channel Flex exterior creates exceptional warmth, comfort, and flexibility in cold conditions. A Drylock cuff opening helps prevent water flushing, while the ergonomic support strap locks the heel securely in place and relieves pressure across the instep. The pull-up heel loop allows for easier entry, making these booties ideal for cold dawn patrol sessions and long winter surf days.
