Dynafit Beast Carbon AT Boots. Excellent condition. Stiff and very light boots with excellent range of motion in tour mode. Solid for both resort skiing and touring. Quality build.
Shell is 27/27.5, BSL is 310mm. Comes with bake-able 27.5 liners. I used them inbounds with both tech bindings and frame bindings. These have ~5 days on them before I had to admit they were too big for me. Here's the Dynafit size guide: https://www.dynafit.com/sizeguide

Here's Powder Magazine's take when it was awarded gear of the year:
The new Beast Carbon is a two-piece, four-buckle, stiff-ass touring boot. It’s basically a refined Khion Carbon, but its upgrades are substantial. The Beast features Dynafit’s new, Master Fit inserts, which make stepping into any low-tech binding easier. Dynafit has also reinforced the boot at its hinge points and reformulated its plastic for improved durability. When disengaged, the shell’s upper cuff is free to move an insane 90 degrees. A slim profile, easy buckles designed for one-handed use, and rugged soles give the Beast the support I’d expect from Euros who climb the Alps. The Beast Carbon is the stiffest touring-specific (not crossover) boot I’ve tested to date, and is an ideal choice for big skiers with a medium-volume foot looking to charge in the backcountry.
