Neoprene Boots O'Neill Psycho Tech 5mm+ RT

The O’Neill Psycho Tech 5mm+ RT Boot is part of O’Neill’s premium cold-water lineup, engineered by the Area 52 R&D team to perform in the harshest conditions and coldest climates. Built with TechnoButter 4 neoprene, the boot is lightweight and flexible, while the internal TB4 Firewall traps and redistributes heat to keep your feet warmer for longer. The construction combines TB4X taped seams on the inside with exterior Fluid Seam Weld, reducing water entry and improving durability. The round-toe design offers extra warmth and natural comfort, while the Arch Strap stabilizes the foot and prevents slipping. The O’Ring Seal around the ankle adds protection against flushing, and the Heel Pull makes getting in and out easy. A durable outsole provides strong grip and resilience under heavy use.
