Built for serious cold-water sessions, the O'Neill Psycho Tech 5mm+ Round Toe Wetsuit Boots in Black are designed to keep you locked in when winter is doing its worst.

Developed by O’Neill’s elite Area 52 R&D team, these boots combine premium insulation with a streamlined round-toe design to maximise warmth without sacrificing board feel. The 5mm construction delivers reliable heat retention, while flexible materials allow natural movement and powerful paddling. 

Finished with a secure, comfortable fit and durable sole for grip on wet rocks and decks, they’re made for long, unforgiving sessions. When the water’s icy and excuses are tempting, these boots let you stay out longer and surf better.
