Men's ski alpine boots La Sportiva Vega - an evolution of four-buckle ski mountaineering boots designed for all freerider ski alpinists who are looking for the perfect combination of power, control, durability and precision of downhill boots with the mobility, controllability and light weight of the new generation. The shell is made of light and durable Grilamid® Carbon Enforced, while the patented Vertebra Technology™ carbon locking system forms part of the shoe's construction and facilitates the transfer of downhill force thanks to the exceptional "125-Flex". Cuff mobility equal to 60° of total deflection, combined with accentuated rolling and the patented EZ Flex™ hinge system. Dual compatibility with race TECH and AT bindings allows for excellent versatility of use. * range of motion: 60 (30° forward, 30° back) * weight: 1475g (half pair) * binding compatibility: Tech AT * G-Shell™: super compact lower shell is only 303mm long for size 27.5. The ultra-light nylon polymer Grilamid® BIO allows the bottom wall thickness of the shell to be reduced without sacrificing stiffness or performance. The innovative element of the rear diffuser ensures an extended range of movement of the shoe. This diffuser element allows an incredible 60° true range of motion in its category - 30° back and 30° forward. * cuff: Vega's ingenious Dual-Axis Cuff™ consists of two separate elements that work together: 1) Pebax® Powered® double-buckle Climbing System Control™ double-density cuff that provides lateral control and increased ankle articulation for technical climbing, 2 ) Exoskeleton Carbon Reinforced Vertebra Technology™, which improves forward and backward power transfer. The Vertebra Technology™ outer cuff is key to the 115-Flex Vega's strong downhill performance. There is also a removable two-position asymmetric rear spoiler for fine-tuning the lean angle and foot position in the lower shell * Dual-Axis Cuff™ allows for a long smooth stride with an extended 60° range of motion, while the G-Shell™ lower component maintains compatibility for touring (AT ) attachment of ski bindings and also for technical bindings. Low 17mm H angle for easy natural stance and all-day comfort. * Shell Line: reinforced area defined by 3D model analysis helps minimize the extent of shell deformation * EZ Flex™ tongue: Pebax® Rnew® bio-based tongue uses the EZ Flex™ hinge system derived from proven La Sportiva mountain boot technology. This innovative design guarantees unrestricted ankle movement on steep climbs and easy walking on flat terrain. An added waterproof seal under the tongue provides protection against snow, ice and water. The position of the tongue can be adjusted on the magnesium hinge above the top of the toe. There are 3 positions for a total adjustment range of 4mm, allowing fine-tuning of fit and gait. * 4BT Tech Last™: 102.5mm neutral flat last keeps the foot in a comfortable, fatigue-free position for precise footwork in technical ski mountaineering terrain. * WarmSole™ insole: real rubber outsole wicks the cold away from the sole, has a smart removable polyurethane ultra-light insulation insole that lifts the foot off the plastic floor of the shoe * EZ-TECH Buckles™ (patented): aluminum buckles with micro-adjustable arm designed to speed up closing and opening * Power Strap: wider offset and hinged velcro closure securely locks the entire cuff mechanism to the leg for efficient power transfer on the descent * Vertebra Technology™: carbon-reinforced Grilamid® durable ergonomic power structure that acts as an exoskeleton * walk/ski mechanism: durable construction , easy to operate even with gloves * adjustable front slope: you can tune the shoe to your personal preferences with this replaceable adjustable system to regulate the slope of the cuff in three different positions (10°, 14°, 18°) * Vibram® Outsole™: double density with 85 shore and inserts on the toe and heel for easier climbing in technical passages. Special centering system that helps attach the boot to the bindings faster * binding compatibility: the boots are compatible with Tech race bindings, AT touring bindings * VEGA liners are pre-formed: if needed, the linings are 100% heat-moldable for those with special fit requirements * ski mountaineering La Sportiva boots * La Sportiva ski alpine boots * brand La Sportiva ski alpine boots
