The Atomic Backland Ultimate is a lightweight ski touring boot designed to help backcountry enthusiasts move efficiently on long uphill approaches and stay responsive on the descent.
Featuring a 98 mm last and low-volume shell, this boot delivers a snug, responsive fit that improves power transfer and edge control. With a flex rating of 70, you get enough stiffness for stability on technical terrain without feeling overly rigid during extended climbs. Weighing just 775 g per boot (size 26/26.5), it keeps weight off your feet to reduce fatigue on long tours.
In ski boots, “last” refers to the width of the shell across the forefoot—a 98 mm last means a narrower fit that locks your foot in place. The flex rating measures shell stiffness on a scale where higher numbers indicate a stiffer boot; at 70 it offers a moderate balance between support and comfort. “Low volume” means there’s less internal space, resulting in a closer fit for more direct response from your skis.
