The Atomic Hawx Ultra 130 S Dual BOA is a high-powered all-mountain boot with a 130 flex on a narrow, low-volume 98mm last. It uses a PU shell and PU cuff with Prolite construction, a Mimic Platinum liner, and a BOA H+i1 Dual Pull system with two dials. Forward lean adjusts between 13, 15 and 17 degrees via Power Shift, ramp angle is 4 degrees, the sole is GripWalk ISO 23223 with cantable grip pads, and a size 26/26.5 boot weighs 1,896g.
The honest trade-off is that this is a precision boot. A 98mm low-volume last and a 130 flex reward skiers with narrow feet and strong technique, and the fit is precise by design.
It is for advanced and expert skiers who want a powerful, responsive all-mountain boot and like the idea of dialing in fit on the fly with BOA instead of fiddling with buckles.
The 98mm last suits narrow feet. Memory Fit heat-molding lets the boot be customized to your foot, the 3D Stretch Toe Box adds room for the big toe, and Dual-Sided Cuff Alignment matches the cuff to your leg angle.
We think the Hawx Ultra 130 S Dual BOA is a brilliant boot for skiers who love to carve hard, delivering a locked-in fit and serious power on every turn.
Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.
This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Conversions are approximate and can differ by half a size between brands.
Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.
Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
