The Pursuit Split Toe Boot was designed for those needing fit, feel and athletic movement. Designed in conjunction with the US Sailing Team, the split toe design helps to increase balance and control, while the low profile rubber sole allows a flexible 'barefoot' feel. Constructed with a lightweight 4mm Neoprene, they are both lightweight and warm while the blind stitched seams offer a waterproof seal for comfort and warmth. Suitable for a wide range of activities including sailing, paddle and boardsports such as stand up paddleboarding and surfing.
