Alpine boots with a skiwalk switch are a dime a dozen these days, but Salomon pretty much started the trend with the original Quest, and it's been making a better version every year since. The new Quest Pro 110 Ski Boot is supported by the same basic ideology as the OG Quest make a backcountry capable touring boot that doesn't sacrifice any of the hard charging qualities of a pure in bounds ripper but almost everything else has been changed, making the Quest Pro 110 lighter, stronger, and more tour friendly than most comparable boots. The foundation of the Quest Pro 110 is its 360 Custom Shell, an innovation that's been sniped from Salomon's in bounds boots. Basically, the shell is made from a heat moldable material that lets it conform to your foot in the same way as the My CustomFit 3D Sport liner heat it up, put it on, buckle it down, let it cool, and you have a fully custom boot that hugs your ankles, cradles your toes, and won't slip, pinch, or give you blisters on the way up. The Quest also employs Salomon's Articulated Sensifit design, which sports a more flexible panel over the instep to allow for pain free donning and doffing of your boots. So the fit's killer, but how does the Quest Pro actually perform' Just fine, thank you very much. The shell and the cuff are joined via Salomon's 24mm oversized pivot, which forms a rock solid connection that transfers energy efficiently into your edges without allowing any lateral slop, and the Hike Ride technology provides a bombproof foreaft connection so you won't have any frontwards or backwards slippage when you're trying to milk the solid 110 flex for all it's worth. In hike mode, the Quest has a surprising amount of cuff rotation, along with a grippy rubber sole and waterproof gusset under the forefoot overlap, so snow won't sneak in and turn your feet into sloppy frozen messes.
