La Sportiva line of ski boots: choose the one that's right for you

Skorpius CR II

When you think of classic ski mountaineering – making your way over a towering crest, wearing your skis on your shoulder wherever bare rock appears through the snow – you should be picturing the Skorpius CR II boots on your feet. Combining lightness for the ascent with maximum performance and rigidity for the descent, these boots refuse to compromise. The innovative shell design, made from bio-based Pebax® Rnew and reinforced with carbon fibres, allowed La Sportiva to reduce the thickness and weight of the materials while keeping the boots remarkably sturdy. Equipped with the SWING-LOCK™ pivotal rotation ski/walk system, these boots allow you to shift gear extremely quickly, protecting the mechanical parts from accidental impacts against rocks and facilitating walking in trickier areas. This season, the Skorpius CR II design was upgraded with the innovative BOA® Fit System, which provides incredibly precise shell adjustment, whether you're going uphill or downhill. Designed for the most demanding ski mountaineers, the Skorpius CR II boots are the ideal companion for tackling significant gradients on technical terrain and in the most remote locations.

Solar II and Stellar II

A new look for the beloved Solar and Stellar boots: this season, these two La Sportiva icons have been equipped with a high-tech upgraded fastening system. Thanks to the BOA® Fit System, which provides an exceptionally precise fit and makes the shell easier to put on and fasten, the Solar II and Stellar II boast all the necessary features for any ski mountaineers, from beginners in search of multi-purpose, high-performance and comfortable boots to experienced users looking for the perfect balance between uphill performance, downhill performance and comfort.

Perfect for heading off-piste, when ski mountaineers need more structured and reactive boots in order to handle any snow conditions, the Solar II and Stellar II two-buckle boots guarantee excellent flexibility and resistance to low temperatures thanks to their bio-based Pebax® Rnew® shells, which ensure optimal mobility to move quickly and safely in any situation.

Vanguard

 Maximum power for the descent, lightness and comfort for the ascent: the Vanguard is a modern boot for adventurous ski mountaineers, designed for both touring and free-touring activities. Thanks to its innovative design and the unique construction of the cuff, the Vanguard is sturdy and reactive, like other boots designed for freeride and alpine skiing, while its low weight and the 63° cuff flex provide comfort and lightness comparable to a two-buckle boot.

Made from high-end plastic materials, combined with glass and carbon fibres, Vanguard boots are a sustainable option thanks to the use of bio-based Pebax® Rnew® 1100, a biocompatible material derived from castor oil. A state-of-the-art addition to La Sportiva's ski mountaineering range, this boot combines advanced wear resistance, lightness, a comfortable fit and impressive power transmission to the skis. To complete the high-tech design, the Ultralon® liner and the durable Vibram® V-Lug sole guarantee greater comfort, precision and strength during high-altitude adventures.

Stratos VI

When the difference between winning and coming second place hinges on a weight difference of a few grams, every single detail in the construction of the product counts. This is precisely where Stratos VI comes in, the latest innovation from Stratos, the Skimo Race boot par excellence. Whether we are talking sprint, individual, vertical or a mixed relay, the Stratos VI is minimalist through and through, thanks to the perfectly balanced selection of materials and the way its shell and cuff are constructed. Both are made of 100% carbon fibre, allowing all foot impulses to be transferred to the binding and consequently to the ski, for the maximum level of precision when walking and skiing. Its particularly extended high flap, combined with the internal foam layer, allow it to grip perfectly on the foot, especially when going downhill. This results in perfect performance in terms of support both on bends and straights. The 80° cuff range provides a quintessential walking experience, offering a very large adjustment range to ensure unparalleled freedom of movement. The construction of the ski-walk mechanism and the closure is specifically designed to prevent it from accidentally opening but also to help athletes go from walk to ski mode in no time, allowing them to stay focused. The Spur-Heel construction is designed to protect the heel from impacts and stress during use, ensuring that the heel and rear part of the shell are as robust as possible. The Vibram Litebase sole provides maximum grip while the S4 insert allows better insertion of the hull into the binding, improved stability and, once again, optimisation of all manoeuvres. All this technology is packed into a featherweight 530G, Stratos VI, the perfect racing machine.

Raceborg II

When extremes are not the only element that counts, Raceborg II comes into action for racers who are looking for a more amenable fit and steadier feel in addition to top performance. The boot is designed with a hybrid construction using a grilamid shell and carbon cuff, for a perfect match between wrap-around, support and fluidity. The generous 75° cuff range provides a genuinely wide range of mobility, essential for perfectly adapting to all stages of a race especially on steep and rocky terrain. The Ski-Walk mechanism is inspired by the Stratos VI and ensures that all idle time is removed in the transition phase, ensuring that athletes can stay focused while manoeuvring without losing time. Moreover, the micrometric closure on the instep is immediate and easy to adjust, allowing for a less extreme and more adjustable fit. The LaSportiva RaceGrip sole guarantees maximum grip on even the roughest terrain and the S4 insert allows better insertion of the shell into the binding, improved stability and optimisation of all manoeuvres. Perfect as a one-stop race boot, as well as a perfect training boot, the Raceborg II represents quintessential performance and comes in a steady but versatile package.
