5 Furnace RT Boot - Men's

What Our Gearhead® Experts Are Saying:

"I reach for the 5 Furnace RT Boot when the water is at its coldest, and comfort matters as much as performance. The round toe gives the boot a natural, relaxed fit that stays comfortable through long sessions, and the graphene interior combined with SMART foam means my feet are genuinely warm even when everything else is fighting the cold."

There is a version of winter surfing where cold feet are just part of the deal, and then there is the version where the right gear removes that problem entirely. The Billabong 5 Furnace RT Boot is built for the second version, delivering maximum warmth and all-day comfort in a round toe design that prioritizes how the boot feels on your foot across a full session rather than just in the first few minutes.

The graphene interior traps and retains heat at the layer closest to the skin, working alongside partially recycled SMART foam to build a thermal system that performs at 5mm thickness without the stiffness or bulk that can make thicker boots feel more like foot prisons than footwear. PRO STRETCH exterior fabric constructed from recycled polyester and elastane keeps the boot flexible and responsive through every movement, while 100% welded exterior seams eliminate water entry points across the entire outer surface. The round toe profile molds naturally to the foot, and the flex arch sole maintains comfort and movement underfoot from the first paddle to the last ride of the day.
