Know before you buy
The split toe design separates your big toe from the others, which helps prevent your foot from sliding inside the boot. This provides better balance and a more direct feel on your surfboard deck.
The Hydrolock system is designed to create a tight, secure fit around your ankle. When paired with the hook and loop fastener, it significantly reduces water flushing, keeping your feet warmer for longer.
Yes, the combination of GBS seams and the Liquid Flex Seal provides a robust exterior that resists wear. While they are built for flexibility, they are tough enough to handle the abrasion of rocky shorelines.
The lining is designed for comfort and heat retention, not grip. The boots include a back ankle pull loop to help you slide them off easily, even when the neoprene is wet.
A 3mm thickness is generally ideal for cool to cold water conditions. It provides a balance of warmth and flexibility, allowing you to maintain dexterity without feeling too bulky on your board.
