Atomic Pro S2 is one of the top skating boots in the Atomic Pro range for fitness skiing. It strikes that balance of being precise but also comfortable for hours on track. The lacing system wraps your foot for a firm hold, while the Split Cuff with 360° Closing allows your ankle to move naturally and still be supported. The Sport Fit is snug but not too tight, and Live Fit inside the boot adapts to your foot shape for an insanely comfy fit. And like all Atomic boots, it’s compatible with all 2-rail bindings including NNN® and Turnamic®.
