The Radical Pro Boot's HOJI Lock System delivers 60 degrees of cuff rotation on a build tuned for efficiency, weighing in at 1270 grams per boot. A Pebax flex tongue is built specifically to improve walkability on the skin track, and a Bootboard lets the fit be customized underfoot rather than settling for a generic shape. What Our Gearhead(R) Experts Are Saying:"I noticed how little the boot fought me on a long approach, the flex tongue let my stride stay natural instead of the stiff shuffle I get in heavier boots. Customizing the Bootboard fit before the trip meant I never thought about my feet once I started skinning."
