Don’t let frigid water temperatures cause you to miss a nice swell—or even to shorten your session. The 5-millimeter Quantum Round-Toe Boot incorporates technology from our Quantum wetsuit line to get you in the water when the temps go south. Featuring 3D stitched seams for watertight warmth and a comfortable, flexible THERMO lining that adds dexterity, these versatile boots will keep your feet right where you want them on your board. A Resist panel at the heel provides stability, while the dual-texture sole gives excellent grip and increases durability. And the convenient pull tabs make it easy to get the boots on and off your feet.
