The Salomon QST Pro 100 TR is a men’s freeride ski boot built for skiers who split their days between groomed slopes and exploring off-piste terrain. It’s designed to offer both reliable downhill performance and the walk-friendly features needed for backcountry approaches.
Featuring a flex rating of 100 and a medium-volume last of 100–106 mm, this boot balances support with comfort. The flex gives you firm enough cuff resistance to maintain control at higher speeds, while the mid-volume fit accommodates a range of foot shapes without feeling overly tight during long days on your feet.
A flex rating of 100 sits in the comfort category for men’s ski boots, delivering more counter-pressure and responsive handling than beginner models but remaining more forgiving than stiffer performance-focused boots. The 100–106 mm last measures the internal width of the shell at the forefoot, offering a snug yet adaptable fit that helps keep feet secure without sacrificing circulation or warmth.
