Most hiking boots are made for men, then sized for women. Not Terradora Flex. Keen started with a fit that follows the natural contours of your foot and then gave it the grip, cushioning, and protection you need to soak up extra trail miles with friends. Keen finished things off by adding KEEN BELLOWS.FLEX technology to the forefoot, so every step feels easier. In other words, it's a boot that can keep up with you, trailhead to trailhead. KEEN.DRYA waterproof, breathable membrane that lets vapour out without letting water in. Perspiration and moisture naturally produced by the foot are able to escape, while at the same time keeping the wet out and the feet dry. ECO anti-odourThe insoles are infused with probiotic technology that naturally breaks down odour in sweat without heavy metals or hazardous chemicals.
