Whether you’re hiking for a few hours or trekking over multiple days, the Men's Ascender Mid Helly Tech® Waterproof Hiking Boots provide key ankle support on changing terrain so you can comfortably bear the weight of your pack. They have a quick break-in period and are easy to put on so you can quickly hit the trails. We 5D printed the upper and constructed the performance hiking compound so it offers both rigid support and cushioning comfort. We embedded a free-flex system in the forefoot for flexing at the right time of the gait cycle, and we layered more at the heel and toe for extra support and protection. The outsole features our HH Max-Grip technology for grip on ledges and other uneven surfaces. With a waterproof membrane and seam-sealed, hydrophobic-treated material, they’re designed to protect you in changing weather.
