Atomic Pro C1 is a fast and friendly boot for classic cross-country skiers, with an upgraded aesthetic that’s modern and sleek. Performance-wise, the mid-cut supports your ankle. An internal heel counter with extra padding supports around the back, and a Quicklace system based on the race models locks in your foot. For extra comfort, the Sport Fit is snug but not narrow, and the lining material and foam have been updated to a softer material, with precise positioning for no pressure points. Step-in is easy thanks to heel loop webbing and the inner boot connected to the gaiter. And the boot works with all 2-rail bindings including NNN® and Turnamic®. Precise, easy, comfortable: a great choice for all athletic cross-country skiers.
