The Billabong Furnace 5mm Split Toe Surf Boot is a warm and comfortable neoprene surf boot designed for surfers seeking warmth, balance and grip in cool to mildly cold water. With a 5 mm neoprene construction, this boot provides sufficient insulation for water temperatures around 8 – 14 °C, making it ideal for fall, spring and mild winter surf sessions.
