Somewhere between an aggressive freeride snowboard boot and a piece of mountaineering expedition footwear lies the Deeluxe Men's Spark Summit Boa Snowboard Boot. Designed with the backcountry snowboarder in mind, the Spark Summit has a stiff, responsive flex, a burly Vibram sole, and bomber durability to handle all your splitboarding and big-mountain shredding needs.
C3 lacing allows you to independently adjust the tightness of the heel, forefoot, and shaft areas of the boot so you can customize the fit to suit your riding. A Boa dial increases customizability even further by allowing you to make micro-adjustments to the ankle area for better heel hold. The DuPont Surlyn backstay stiffens the boot for reliable support and response that will last over time. A Sympatex waterproof membrane and leather upper prevent moisture from seeping into your boots throughout the day, even when you're postholing your way up the mountain.
The Thermo Flex Premium liner is heat-moldable to allow you to get the perfect fit for your foot, and the E-Lacing system help you crank down the tightness. An EVA midsole absorbs shock from harsh landings and reduces vibrations for a smoother ride. The rugged Vibram Icetrek outsole has aggressive lugs to provide traction on icy surfaces, and has a backwelt that's compatible with semi-automatic crampons. It's also super-durable to resist damage from hiking across jagged ridges and rocky approaches.
