Built with a Thermo Dry Inferno (TDI) interior and flexible Channel Flex exterior, these boots deliver exceptional warmth, comfort, and flexibility for cold water surf sessions. The Drylock cuff opening helps prevent flushing, while the ergonomic support strap keeps your heel securely locked in place and relieves pressure across the instep.
