La Sportiva Sparkle 2.0 Women's

Sparkle 2.0 is the female version of the evolved, four buckles ski mountaineering boot dedicated to skimountaineers and free-riders looking for the perfect combination of power, control, endurance and precision of an alpine boot, with the qualities of mobility, maneuverability and lightness of a new generation ski mountaineering boot.
Downhill, the transmission of power and control of the ski is accentuated by the use with the TR2 safety binding, thanks to the perfect compatibility guaranteed by the Skitrab system with which it is sufficient to remove the two metal features. The shell is made of lightweight and durable Grilamid while the patented Vertebra Technology ™ loaded carbon locking system, is a structural part of the boot and facilitates the transmission of power in the downhill phase thanks to the exceptional "125-Flex" qualities of flexibility. The mobility of the shell equal to 60 ° of the total excursion, together with the accentuated gliding and the system patented EZ Flex ™ system of the innerboot, accentuate the walkability of the product, usable also for technical passages on rocks and slippery surfaces thanks to the full Vibram dual mix/double density outsole. The unique triple compatibility with TECH race bindings, AT and Trab TR2 bindings, allows for unprecedented versatility. A revolutionary evolution for lovers of powder.

FEATURES:

+ G-Shell™: Our super-compact lower shell is only 303 mm long for a size 27.5. We use the ultra-lightweight nylon polymer Grilamid® because it allows us to reduce the thickness of the lower shell wall without sacrificing stiffness or power. The compact shape allows for precise footing during technical ascents. The innovative Rear Diffuser element powers the boot’s extended range of motion. This diffuser element allows incredible best-in-category true 60° range of motion -- 30° rearward and 30° forward (buckles closed). Open the buckles and you get an additional 10°-15° forward range of motion. The diffuser also works to keep your heel locked down when the boot is flexed in the forward direction.

+ Cuff: The Spectre’s ingenious Dual-Axis Cuff™ consists of two individual elements working together: (1) a Pebax® dual-density two-buckle Climbing System Control™ cuff that provides lateral control and increased ankle articulation for technical climbing, and (2) a Carbon Reinforced Grilamid® Vertebra Technology™ exos

+ EZ Flex™ Tongue: The PEBAX® Rnew® bio-based tongue uses our EZ Flex™ hinge system derived from La Sportiva’s proven mountain boot technology. This innovative design guarantees unrestricted ankle movement for steep ascents and easy striding on flat ground. An added waterproof seal under the tongue provides protection against snow, ice and water. The position of the tongue can be customized at the magnesium hinge over the top of the toe box. There are 3 positions for a total adjustment range of 4 mm to allow fine-tuning of fit and walkability.

+ WarmSole™ Insert: Fact - rubber outsoles conduct cold up from the bottom of ski boots. The Spectre sports a clever removable polyurethane ultra-lightweight insulating innersole that raises your foot up off the plastic floor of the boot and makes this one of the warmest four-buckle boots on the market.

+ Pegasus Buckles™ (patented): these aluminium buckles with micro-regulation have been created with minimalist design and function for the most efficient opening and closing of the boot and the entire volume of the boot.

+ Vertebra Technology™: Carbon reinforced Grilamid® hardwearing ergonomic power structure that works like an exoskeleton (patent pending). It is the backbone of the cuff construction and guarantees maximum security and precision during downhill ski mode. No need for a stiff tongue, the power comes from the Vertebra when it is locked out in downhill mode.

+ Binding compatibility: the boots are compatible with race Tech bindings, AT touring bindings and with the esclusive Skitrab TR2 safety binding (just removing the two metal parts on the back).
