Lightweight and fast are the best words to describe the Dynafit TLT 6 Mountain CR Boot. This is an expert level boot that can be customized in a number of ways. It has a removable Downhill Booster tongue that can be popped in for added stiffness. The Driving Spoiler 2.0 can be adjusted for different lean angles and the Ultra-Lock power strap can be cinched down to lock the boot to your leg. The Claw sole makes for easy walking and works with crampons when climbing ice or mixed routes.
