La Sportiva is turning things upside down. This time, we are talking about ski walk/mode levers. The new Speedfire™ closure system incorporates a rear lever that latches at the top instead of the more-familiar bottom where it can become packed with snow when booting. The design goals remain the same as the original Spitfire: speed and performance. The former is accomplished through use of lightweight materials and one-motion transitions. The latter goal is met by incorporating carbon fiber reinforcements into the upper cuffs and stiff Ergal aluminum into the vertebrae. Sportiva also tacked on another goal: compatibility. The Spitfire 2.0 is the first boot to work with step-in frame bindings, Dynafit-style tech bindings, and also the unique TR2 binding from Ski Trab. The result of all these goals is a truly special ski boot that meets the needs of similarly goal-oriented mountaineers.
- WarmSole™ inserts are an extra barrier between you and snow, good enough for cold days.
- Dual-density LazerGrip™ soles are extra tough in the toe and heel where abuse is highest.
- SPEEDfire Closure System™ is a one-motion transition and cuff adjustment mechanism.
- Forward lean can be adjusted amongst three different settings by changing the lock latch.
- CRP Cuff™ is a carbon-reinforced polymer upper shell that offers a smooth-yet-stiff flex.
- 3S Insert™ offers compatibility with tech and TR2 bindings, while deep welts fit into step-ins.
- 2BT Tech Last™ is a lower shell mold that offers an improved fit while being tech-compatible.
- 2BT Tech Heel™ is a volume minimizing shape in the heel to help prevent blistering.
- Slightly-less-rockered sole fits more crampons but still provides easy walking on rock.
- Cuffs allow for 68° of ankle articulation so there is nothing impeding the longest of gaits.
- G-Shell™ lower is a Grilamid mold that is light, stiff, and resistant to low temperatures.
- EZ Flex™ is a Grilamid tongue with flex spots to provide unrestricting walking and good skiing.
- Optional spoiler (+22g) and power strap (+22g) included if you want more beef for the descent.
- Pegasus buckles have been incorporated from the Spectre that are easy to use and fine tune.
- Skimo liners are thermo-moldable Paulau® with EZ Flex ankles for good fit and movement.
- Borrowed from high-altitude mountaineering boots, a patented lacing system has double tension.
Update 2016/17: The Spitfire has a minor version number increase. The "2.1" has a re-designed upper buckle that makes it a bit easier to open and close. The rest of the boot remains awesome.
Update 2017/18: Sportiva updated the color scheme and re-worked the instep buckle with a toothed design.
