Rated 4 out of 5 by solid boot I've had boot for a month and used about 10 days. So far no major blisters, but some rubbing on my shins is all. I fit boot at home because I don't live near boot fitter. If I fit again, I'd heat at 270 instead of 240. I swapped out insoles for super feet, then used cut-out middle of insoles to bolster arch support. If you get a good deal on the boot, then I think it's worth pulling the trigger February 9, 2014
Rated 5 out of 5 by Great fit and lightweight ! I have not had the chance to use this boot on the hill yet, but it is a great fit (around the house), and I am a big fan of the Boa Lacing System and lightweight. Also a fan of three buckles. I am not a racer, or super aggressive skier and have never had much use for the lower toe buckle on 4 buckle boots. Another big plus is the ease of entry/exit on this boot compared to my regular alpine boots. January 6, 2014
Rated 4 out of 5 by Great Fit ! Quick Mail Out from BD ! I have a bear paw of a foot, so this boot is perfect ! Light weight but strong, and easy to adjust from walk mode to ski mode and back. I replaced the Liner right away. It is flimsy, and the ratchet lace up system is best suited for a snowboard boot. BD mailed these out and I got them in a week, all the way up to Canada !

Rated 2 out of 5 by Runs small Have tried three sizes of this boot and it is still small. I wear size 9-9.5 and 27.5 is to small lengthwise. I'm going to a size 28. Bummer since now I need a bigger binging also. Very costly and frustrating! December 29, 2013
Rated 5 out of 5 by Prime AT boot... Fit comfy right from the start. I like wide and light! Bootie super better than lesser model!! Intend this boot to be my "go to" on hill this year both for free time and work assignments. November 13, 2013
