Toasty toes in cold surf.

Winter and transitional seasons often produce the best swells of the year, with offshore energy exploding onto beach breaks and offshore reefs alike. The problem lies in freezing-cold water, which numbs your toes in a matter of minutes. Solving the frozen-foot dilemma, the O'Neill Men's Psychofreak ST 3.5mm Boot keeps your feet nice and toasty while promoting sure-footed dexterity with its deep split toe.


TechnoButter 2 Air Firewall neoprene retains toasty warmth, especially considering the fluid seam welded exterior and fully sealed interior. Ultimately, this combination of heat-trapping neoprene and fully sealed seams keeps frigid water from seeping through and numbing your feet. Additionally, the Leash Stop Toe Guard resists snagging, so your leash won't hook up on your booties and unexpectedly take you down.
