It’s time to reimagine what’s possible with the Spark Fusion. The Spark Fusion features a significantly smaller footprint and a design optimized for skinning, hiking, and riding. To ensure it can withstand the harshest conditions, this rugged backcountry boot features our proven Rock Guard that provides protection from rocks and ice. The Spark Fusion is equipped with a snow shield that protects the lower part of the boot from snow, ice, and moisture to keep your feet dry. The boot’s Backcountry liner provides a truly custom fit and sports a flexible toe box that offers a precise yet forgiving feel. For even greater comfort and control, the Spark Fusion uses our L3 lacing system with speed lacing* to cradle the foot and calf, and it features the BOA® Fit System to lock down the ankle and heel. Thanks to this zonal fit, you can lock your ankle and forefoot in place while allowing your leg to move within the boot whe ascending. For unrivaled traction, the Spark Fusion also boasts a Vibram Eastridge sole. The boot’s plastic backwelt features a grooved heel for accommodating semi-automatic crampons. The future of backcountry snowboarding is about to begin with the Spark Fusion.
