Whether you wear Keens Womens Targhee II shoe for trail running or just roaming around the campsite, youre going to feel a comfortable difference over conventional waterproof active wear shoes. Thats 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 took a route less traveled and used 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 dont feel soaked in sweat like you would in other weatherproof trail running shoes. The heel of the Womens Targhee II features Keens S3 heel support structure, a special shock-absorbing design thats engineered to support your foot on impact, minimizing your chances of twisting an ankle on rolling terrain. Like other Keen performance shoes, the Womens Targhee II is all about stability, but if youre looking for drier socks at the end of the day, the new Dry System Technology is worth checking out--especially if you forgot to pack extra socks for the return trip home.
