Product Description

The O’Neill Psycho Tech 5mm+ Round Toe Wetsuit Boots are built for surfers who want maximum warmth and protection in freezing water conditions. Featuring O’Neill’s TechnoButter 3 neoprene with a TechnoButter Firewall interior, they combine superior insulation with lightweight flexibility for serious cold-water performance.

The round toe design offers extra warmth and comfort compared to split toe boots, making them ideal for long winter sessions in icy water. A durable outsole with an anatomical shape delivers grip and stability, while the arch strap secures your foot for a locked-in feel. O’Neill’s O’Ring ankle seal helps prevent water flushing, and the seam construction — TB3X taped with exterior Fluid Seam Weld — ensures a watertight, long-lasting build.

Part of O’Neill’s premium Psycho Tech range, these boots are engineered by the Area 52 R&D team to perform in the harshest conditions and keep you charging through the depths of winter.

If you surf in seriously cold water, the extra insulation over a split toe design is noticeable, and the TechnoButter Firewall lining makes a huge difference. A go-to option for cold-water surfers who prioritise heat retention above all else.
