H10 Sole & Heel Pull

The single-layer rubber sole is engineered to deliver excellent board feel and flexibility without sacrificing grip. Multi-layer sole reinforcement improves durability, while the integrated heel pull loop makes entry quick and easy.

Split-Toe Design

The split-toe construction isolates the big toe to enhance balance, agility and grip. This improves control and reduces internal foot roll during dynamic surfing movements.

GBS, G-Tape & BoltDry+

Glued and blindstitched seams combined with full internal G-Tape reinforcement help keep water out. Paired with the BoltDry+ Graphene-infused lining, this system keeps your feet warmer than ever in cold conditions.

S-Seal Ankle

A silicone ribbed ankle section locks the boot securely to your wetsuit, minimising water flushing. The taller boot height extends coverage up the calf, helping maintain a stable thermal microclimate during winter sessions.

Size Guide

Fit tip: For the best thermal performance, wetsuit boots should fit snugly. If you are between sizes, consider sizing up to avoid restricting circulation.
