Freaky warm.

Pick up the O'Neill Men's Mutant 3mm Split Toe Boot and head into the water instead of running back into your car after you've dipped a toe in. FluidFlex Firewall neoprene cranks up the warmth, while the split-toe design allows for precise control when you need it most and the rubber sole scrambles over barnacles and rocks without breaking a sweat. The seams are glued and blindstitched for superior waterproofing, and the SuperSeal closure keeps water from creeping in from the top.

Warm and Comfy

  • Familiarity: I've used it several times

I picked these up for kayaking and was not disappointed. The split toe design does not detract from mobility and helps keeps your toes warmer than a standard style.
