Opinions are like assholes; some are larger than others. I'll take the word of a guy who has fitted 900+ pairs of the things over the word of others, EVERY TIME!
The idea that a custom skate should fit perfect right out of the box is scary to me. Whether it's scanning, measurements, whatever, there will ALWAYS be something not quite perfect, and there will be tinkering needed, even just the slightest bit, in order to get it 100%. Maybe YOUR idea of 100% is less than, only because TO YOU, the skates fit you BETTER than your last pair. You might be surprised what can be done at a far less cost than ordering custom skates.
With that said, lots of Kool-Aid being consumed here lately; custom skates, Sparks, crazy times!
