The Mindbender Alliance 110 are freeride/ free ski touring boots for women by K2.
Mindbender range :
The Mindbender range has been designed targeting several major points: lightness, liveliness and fit customisation to meet the demands of freeriders, who are more and more fond of wide open spaces and therefore of hiking up to a summit with skis on their backs.
To achieve this, K2 has developed the Powerlite Shell, which is based on the principle of incorporating reinforcements in the sensitive and strategic areas of the boot, while paring back the less essential parts. This seems to be the basic design premise, but it's also a task requiring craftsmanship that the American brand has achieved with the use of 4 different densities of TPU. All this offers a perfect balance between agility, power and lightness, which allows for easy climbs and all the support you expect from a freeride shoe on a descent.
Mindbenders obviously have low-tech inserts for touring bindings, although they are perfectly suited for alpine bindings. They also have a 50° travel giving you an extremely natural walk, whether you're on flat terrain or in a steep area. The GripWalk soles are also perfectly adapted since their curved "rocker" shape allows for easy walking, and the grip is adapted to technical terrain.
In addition to the weight, there are many innovations in the shoes in this range. The Fastfit Instep cushions the top part of the inner boot to offer an easy fitting. Struggling to get into your boots on a cold February morning will be a thing of the past!
And as you can never have too much good news, the Powerlite shell and Precisionfit Pro Tour integrated liners are totally thermosettable, so you can perfectly customise your boots. A custom fit to cocoon your precious feet! The liners are made from high-quality Ultralon foam and have asymmetrical tongues for a more ergonomic fit.
Mindbender 110 Alliance :
This 110 version is the stiffest model in the Mindbender women's range. It features a 45mm Ripcord Power Cinch strap offering maximum grip and support. With a high flex of 110, this version remains ultra-efficient and precise, so you can tackle the steepest slopes and unleash the speed when you hit the powder.
The integrated PrecisionFit Pro Tour liner is also the most advanced of the brand: 100% thermoformable, the high density Ultralon foam ensures maximum durability and unrivalled support, even at high speed!
Simply put, this Mindbender Alliance 110 is designed for light, experienced or expert freeride who want innovative, durable and high-performance equipment.
