O'Neill Hyperfreak Fire 3mm ST Boot

O'NEILL HYPERFREAK FIRE 3MM ST BOOT

When Cold Hawaii calls, it's about being in the water – not on land.

The O'Neill Hyperfreak Fire 3mm ST Boot is a technical neoprene boot designed for surfers who demand high flexibility, efficient warmth and maximum board feel in cool conditions. The Hyperfreak Fire series builds on O'Neill's most mobile platform and combines it with insulating materials to keep feet warm without losing board feel.

The 3mm neoprene construction provides targeted insulation, while the split-toe design improves balance and control during active surfing. The snug construction and flexible materials ensure the boot follows the natural movement of the foot throughout the session.

More warmth. More control. More time in the water.
