Considered the best single leather mountaineering boot on the market, this year's evolution of the La Sportiva Men's Nepal Evo GTX Mountaineering Boot takes hardcore climbing boots to another level. From the first step, a new GORE-TEX Duratherm lining makes the boot completely waterproof and warmer for high altitudes and extreme cold. A new breathable tongue and intergrated anatomical elastic snow gaiter keeps the foot drier, managing perspiration and big water droplets. With the addition of the patented 3-D Flex ankle hinge system, and sticky rubber rand the Men's La Sportiva Nepal Evo GTX Mountaineering Boot climbs better than ever. The sole has a new tapered HP3 midsole with shock absorbing polyurethane ("PU") inserts under the heel and the ball of the foot for support. A new IBS (Impact Brake System), designed exclusively with Vibram, softens impact on hard ground and improve traction by 20%.
