Billabong 3mm Furnace Ultra Boot

The Furnace Ultra HS 3 mm boots are engineered for high-level performance in cold water, offering you optimal grip. The 3 mm construction strikes a perfect balance between warmth and board feel, while the sleek split-toe design enhances control and reduces bulk. The ankle section provides firm support and keeps water out, and the textured sole ensures reliable traction on wet reefs and rocks. Finished in classic black to complement the rest of your gear, these men’s boots are ideal for winter sessions, reef excursions, and any scenario where performance and protection are essential.
