Whether you're training or competing on the trail stability is everything. Keen's Ochoco Waterproof shoe emphasizes stability without compromising on all-weather comfort. That's because unlike other trail running shoe manufacturers who opt for using the same waterproof membranes found on practically every running shoe on the market Keen's Ochoco took a route less traveled with a new eVENT® membrane fabric with Dry System Technology for better breathable comfort in wet weather. The difference is one that you can feel--most waterproof/breathable technologies require that perspiration condenses to moisture before it can pass through the membrane. eVENT® membrane fabric allows sweat to pass through in vapor form so your feet don't feel soaked in sweat like you would in other weatherproof trail running shoes. The heel of the Ochoco features Keen's S3 heel support structure a special shock-absorbing design that's engineered to support your foot on impact minimizing your chances of twisting an ankle on rolling terrain. You'll also find Keen's Quindensity midsole a new chassis design that allows considerable flex during toe-off without compromising forefoot protection. Combine the flex along the sole with the free-flex asymmetrical lace up top and you'll find that the Ochoco bends where you need it without leaving you feeling exposed. This is comfort you'll appreciate every step of the way.
