Next in line to the TLT6 Performance boot is the Dynafit TLT6 Mountain CR Ski Boot, made for fast ski mountaineers, winter climbers, and adventurers on demanding ski expeditions. Like the Performance boot, the Mountain boot wields hardcore power yet feels comfy as a bedroom slipper. A bomber Grilamid shell, stiff tongue, and surrounding last, it will cower to no downhill challenge. And its abrasion resistant materials stand up to summit happy use and abuse you know what that means. A Custom Ready thermo moldable liner provides warmth and optimal antomic comfort, because demanding terrain means time in the boot, and time in a comfy one means the difference between reveling at the peak or wishing for home in the face of all that pristine glory. And that's a shame. Equally at home on fast, techy descents and mixed alpine climbing, the TLT6 Mountain is one of the most well rounded and complete boots in Dynafit's AT collection.
