O'Neill Psycho Tech 3mm+ Split-Toe Boots

The redesigned O'Neill Psycho Tech is their most advanced boot, with an O'Ring entry and liquid-sealed Sidewinder seams for superior watertight performance. The O'Neill heat-retaining TB4 materials and rugged Krypto Armor enhance comfort, warmth, and durability while preventing overexpansion. A wrap-under arch segment pairs up with their high-performance All-Terrain Mudder Grip for improved stability. Built for the harshest conditions.
