Solving the infuriating issue of heel lift, the Salomon Ivy Boa Snowboard Boot uses a time-tested Boa lacing system in tandem with Salomon's STR8JKT heel retention harness for a locked-in, supportive feel. To tighten the boot, simply spin the Boa dial to your desired tightness, then pull the STR8JKT handle nice and tight, and boom! You're now ready to shred without any slop or excess movement inside the boot that'd otherwise affect responsiveness. The Ivy Boa's medium flex is dialed for park domination and all-terrain cruising, keeping you comfortable and well supported, but without being overly stiff like some freeride boots. The heat-moldable Diamond liner provides a glove-like fit as you ride it over time by conforming to the unique contours of your feet. Salomon placed an Ortholite C2 footbed in the liner to soften the sting of heavy landings, while remaining breathable to prevent funkiness after a long day of shredding. It's finished with a Flight sole of impact-absorbing EVA foam combined with grippy rubber traction where you need it most.
