Crafted for a women"s specific fit, the La Sportiva Women"s Nepal GTX Evo Mountaineering Boot is arguably the best leather mountaineering boot on the market, providing uncompromised performance for the serious female alpinist. Evolving to a new design level, the Women"s La Sportiva Nepal Evo Mountaineering Boot"s improved upper adds a GORE-TEX Duratherm lining to make the boot completely waterproof and warmer at high altitude. A new breathable tongue and a patented 3-D Flex ankle hinge system with intergrated anatomical elastic snow gaiter provides enhanced moisture management. The sole has a new tapered HP3 midsole with shock absorbing polyurethane ("PU") inserts under the heel and the ball of the foot. A new IBS (Impact Brake System™), designed exclusively with Vibram, softens impact on hard ground and improves traction by 20%.
