ISPO Award Winner 2024: HEAD Kaliber 130 MV GW BOA2

When it comes to ski boots, precision and comfort are non-negotiable, especially in the performance category. This new HEAD Kaliber 130 MV GW BOA2 ski boot sets a new benchmark for precision. Every design decision was made to optimize both fit and performance. This boot features an exclusive BOA shell construction, an all new last, geometry and liner. 

So instead of applying BOA to an existing ski boot design, Head fully integrated the BOA system into the cuff and lower boot of the Kaliber ski boot, unlocking its potential. Starting with the precision fastening technology, the brand engineered an extraordinary ski boot around it.

Thought-out to deliver micro-adjustable precision, consistent closure, and reliable support, this boot design ensures skiers can focus on the slopes, not their gear. The new BOA cuff auto adapts to the skier’s calf shape as the fit system tightens. The cable can move freely along, allowing for the upper and lower cuff to adapt to the calf shape automatically and independently. The BOA cuff also self-balances and can be adjusted from a single contact point, while a traditional buckle cuff must be manually adjusted at two distinct points.

The boot also features a new bi-injection construction: The stiff frame’s high back profile provides strength and allows the use of softer plastic in the forefoot areas. Together with an extended overlap shell, it provides an even footwrap down to the toe, molding to your foot and maximizing BOA functionality. The dual BOA integration is also available in a 110 flex and a 105 women’s version. The ISPO Award jury was really impressed by the execution of this boot and the great fit achieved with the double BOA construction. 

A new 100 mm performance last was shaped for Kaliber, with more toe space and a new heel and ankle shape and cuff. This new fit is closer around the leg and achieves precise control. The new Synapse Pro liner is thinner and more anatomical. A dual-density tongue provides great precision and impulse transmission, while integrated liquid fit technology allows precise fit customization. It has graphene woven in, which is a revolution in temperature regulation: it will keep you warm or cool, as needed, depending on the conditions on the slopes. It also counteracts bacterial reproduction, is anti-static, and resistant to wear and washing.

• Dual BOA integration for a better fit
• New bi-injection shell construction and liner with graphene for thermoregulation
• New anatomical shape in the last and liner
