Black Diamond makes an impressive entry in the freeride touring category with the Shiva Mx. It’s a beefy, take-no-prisoners boot substantially increases the comfort margin when touring for big mountain terrain. But hit the gym before long tours—this is a hefty boot to haul up a mountainside.
Black Diamond’s Shiva boot has a Triax frame couples with overlap construction, four buckles, and 110 flex for optimal power transfer. The Shiva is also built for touring with a ski/walk mode, 40-degree cuff range, and the ability to switch between alpine and AT soles.
Black Diamond established itself as built for the ascent. The Shiva (and the Factor Mx, its unisex counterpart) marks a new commitment to the down. But this boot is no naïve rookie—the Shiva outperforms many boots in the freeride/AT category on the up, and particularly shines on the down.
We like the amorphous “freeride” category because these products offer all the backcountry-specific functions without losing resort utility. That’s especially true with the Shive. Swappable soles; a stalwart tour mode; and best lateral stiffness in our head-to-head test makes it a true MVP when you’re confined to the resort, and even more so in the backcountry.
Pile on the Miles
Sturdy construction, like the low-profile buckles and lightweight Triax plastic for consistent flex, promises these boots will stand up to on-snow abuse. If you need a versatile boot that can handle a few seasons of wear at the resort, on the bootpack, and in the backcountry, this is a solid investment.
