The 3DS is the stiffest boot in the line. This series is built more like a snowboard boot, set to conform to a rider?s leg as much as their feet. Regardless of support and stiffness, the 3DS is still one of the easiest boots on the market to get into. Combining a soft, conforming neo sock and smooth Lycra liner means more time on the water without frustrations in the water. SIZES: Sm, Mini md, Md, Md/Lg, Lg, Xl, XXl Features: ? Closed Toe ?
