So, I'm NOT a fit expert and NOT a skate expert, but after 2.5 weeks, 20 hours on the ice, 3 bakes, and twisting myself in knots with ace bandages and ratchet clamps, I have to say that I'm not entirely sure I'd recommend these skates to someone that has severe low volume issues in a traditional skate. The Trues are designed to fit SO close to your foot that I can easily see how they wouldn't necessarily be a solution to a skater that has problems with off-the-shelf skates fitting 'too tightly'.
Yes, the skates are built 'custom to your foot', but in this case, 'custom to your foot' also means 'tight to your foot'....no, really 'TIGHT to your foot'. There is very little dead space (or, almost NONE, if they fit the way they're designed to fit), and that is BY DESIGN. Hell, they even recommend that you use a shoe-horn to get them on! Put differently, if my experience is any indication of 'normal', I'd have to say that if someone is having volume issues in an off-the-shelf skate, they're probably going to have volume issues in a True skate, too. Now, said volume issues may be eminently more 'solve-able' in a True, but I've gotta believe that going into the scan process with the idea that these skates will be a warm, fuzzy panacea of slipper-like comfort is only setting yourself up for disappointment.
Personally, my issue remains the complete opposite. Everything feels great, but my heels do not stay locked into the back of the boot. I'm going to do a rebake this weekend (hopefully - got a tournament to coach) and leave the top eyelet undone. Then, I'm going to do some targeted molding of the area around my heels/ankles with my heat gun and a small arsenal of ratchet clamps and see if that does the trick....
