For wet and slippery missions, there are Bedrock Sandals Men's Cairn 3D PRO II Adventure Sandals, the ultimate adventure sandals outfitted with the new Hook-heel strap, extra-sticky Vibram® Megagrip outsole, and molded 3D footbed. The Pro II G-hook and loop system locks in the heel strap like it does the front, for a super-secure fit that won't fail in the frothiest rapids or thickest silt. Patent-Pending design features premium webbing, three adjustment zones, and sole-hugger wings for locked-in stability.
