We make such a big deal about "quiver-of-one" equipment because backcountry skiing always seems to involve sacrificing one thing for another -- more power but with added weight, touring efficiency but with less downhill performance, powder flotation but with less edge control, and on and on. Salomon aims to put the kibosh on this outdated quid pro quo, equipping their women's Shift Pro 110 AT boots with every tool you'll need to explore the entire mountain without sacrificing anything along the way.

With a stiff 110 alpine flex, fiberglass Coreframe insert that increases power through rigidity, the boot lends alpine performance  with improved terrain feedback and power transmission. As one of Salomon's lightest offerings, however, the Shift Pro 110 AT is entirely comfortable on the skin track. The simple Surelock skiwalk mechanism boasts a wide range of motion while a women's-specific liner follows the movement of the cuff in hiking mode for natural, more efficient strides.

Don't fret about sacrificing comfort, either. S/PRO’s 100 mm inclusive fit and Custom Fit 4D Pro liner with thermoformable Talyn combined with a softer Sensifit insert provide better instant fit and more comfort when touring. 10 minutes in the oven and you'll have a custom fit, with Salomon's thin wall construction keeping the foot closer to the shell for increased power and terrain response.
