The original 100% 3k Twill carbon-fiber boot, the Stratos EVO, is the result of years of research and development by La Sportiva and its winning skimo team. At only 558g (1lb 3.7oz) without the liner, these are the lightest boots on the market that fully cover the liners so you don't end up with wet feet after booting or skinning through powder. Designed for fast race transitions, the EVO has only one buckle which integrates the buckle with the ski / walk mode switch. And with features like a built-in shock absorber on the anchor / leverage device, the boots ski suprisingly well.

• Super soft thermo-formable Stratos liner (165g / 5.8oz) has a patented lacing system and flex zones for maximum comfort and a tight fit.
• Optional bikini-style liner (105g / 3.7oz) is an ultralight two-piece system designed specifically for racing.
• Spring-loaded, one-motion lock lever will get you transitioned as fast as possible.
• Lock lever is designed to absorb shock between the medial tibia and cuff while skiing.
• Tech fittings are made of high resistance steel, with the rear being coated in carbon.
• Integrated strechy gaiter with zipper is easy to get in and out of while preventing snow and water from soaking the liners.
• Grippy Vibram soles have a highly durable 75-shore rubber in the toe and heel to prevent wear.

** Please be warned that carbon fiber (even the strong 3k kind) is not the most impact resistant material and there has been at least one report of a shell cracking with a hard blow from a rock. However, if you plan only on racing, careful touring, and resort uphilling, these boots will get you to where you're going in a hurry. Due to the specific nature and price of the Stratos EVO, please contact us to order the boots so we can get you the best fit possible.
