The Helly Hansen Cascade Mid HT Hiking Boot is up to unpredictable weather conditions. The HellyTech Performance membrane sandwiches a waterproof and windproof membrane in between a water resistant outer layer and breathable lining to keep us comfortable and dry in wet and dry conditions. We like the mix of proprietary Helly Hansen technologies that improve our hiking experience, too, including cushioned insoles, arch support, a reinforced heel cup and toe cap, and durable, multi-directional grip for traction on all hiking surfaces.
