The Men's Olympus Mons Evo Mountaineering Boot is La Sportiva's solution for ascending 8,000 meter peaks like Everest. This superlight double boot features an insulated inner boot that you can walk around base camp in, a thermo reflective lined outer boot for extra warmth, and a durable Cordura gaiter with anti perforated Kevlar reinforcements. La Sportiva also added a thermo reflective lining on the inner boot's footbed to reflect heat back to your foot. The Olympus Mons Evo also features a carbon fiber insole for support, and micro cellular closed cell foam helps fend off the icy cold. Microporous EVA makes the midsole cushy to keep your foot comfy, and TPU inserts ensure longevity. La Sportiva used Vibram's reliable rubber to give the sole plenty of traction, and the rubber rand protects the boot from wear and tear so you can tackle 8,000 meter peaks weekly if you like.
