Head Kaliber 130 MV GW BOA2 Ski Boots 2026

The Head Kaliber 130 BOA is the real deal—it’s a proper, high-performance boot that just happens to use the BOA system to wrap the shell and cuff. Having skied this boot from the East Coast to Austria, with the Head team, we can honestly say it's one of the best boots Head has dropped in a long time. With a 130 flex and a 100mm last, the Kaliber is designed for more aggressive skiers who want precision, power, and a fit that doesn’t make you want to rip your boots off after lunch. The midfoot hold is snug and secure, but never punishing. Just a smooth, micro-adjustable fit that locks in and stays locked in. 

Performance-wise, the Kaliber brings the heat for intermediate to expert skiers. It's powerful, with a progressive flex that doesn’t feel dead or overly punishing. There’s a surprising amount of rebound and response, and it feels just as confident railing high-speed groomers as it does mobbing through crud or tight trees. The liner molds well and helps dial in the out-of-the-box fit, which is already pretty anatomical. While it isn't the most precise boot on the market, it's precise where it counts and can be worked to accommodate higher volume feet that end up in this boot. 

Bottom line: Head nailed it. The Kaliber 130 BOA is a clean, responsive, all-mountain charger that skis as good as it looks. This is how modern ski boots feel—precise, powerful, and way more comfortable than they have any right to be.
