These boots fit great. Make sure you get them big enough to fit comfy socks. They have a great Achilles Tendon support in the liner, and fit snug and secure. Haven't broke the walk mode yet, but most of the reviews say it'll happen. The BOA lacing is really really awesome. So easy, even with gloves on. Hard to find the Dynafit sole pieces for the green color, BD said they weren't expected in stock until Winter. I use them with Fritschi's for AT.
