Liking them so far...
I have about 25 days on these boots, about 50/50 as far as resort/touring days. I have been skiing the Scarpa T-race for years before this boot came out. In contrast to the T-race I think the Custom is slightly stiffer in the bellows. One big advantage over the current T-race is the Custom has a tour mode and a great one at that. The Custom when in tour mode has a ton of freedom of movement. Compared to similarly big and stiff boots the Custom is lightyears ahead as far as ability to tour. As far fit goes, I was a 28 in Scarpa and I am also a 28 in the BD Custom (I have a 10.5 street shoe). The Custom's heel cup is large and comfortable. There is no need to even snug these boots up for the hike up, I leave all the buckles on the loosest setting for hiking. The boa lacing system in the liner and big heel cup keep my foot right in place. One of my first days touring with this boot we skinned 7,000' and no blisters or even hot spots! So far my only major complaint is with one of the buckles. I buckle my boots TIGHT and sometimes have problems unbuckling the higher of the two lower buckles, especially with gloves on. My solution is to tie on a very small scrap of 3mm cord to the end of each buckle so I can grab that with a gloved hand.
