Built to drive wider skis while maximizing walking efficiency, the all-round Atomic Backland XTD 110 is a go-anywhere ski touring boot with a medium flex and 100mm last that fits medium-width feet. It’s built with Prolite technology, a streamlined construction that wraps the foot, while reinforced key zones deliver strong ski performance. The open-throat, Hybrid Overlap shell improves step-in/out and the Cross Lace 2.5 Z-cable closure system delivers a supremely uniform fit. Memory Fit provides advanced heat fitting technology to allow for a fully personalized shell, cuff, and liner. The PVC-free 3D Gold Tour liner boosts breathability and heel hold. One of the best skiing and most versatile boots in the Backland series, this boot delivers 74° cuff rotation to ensure natural movement while skinning. A full-rubber sole is compatible with Atomic Shift and all MN, MNC, and Pin bindings.
