Yeah I figured they would loosen over time when I had the 9 on foot fit as snug as it did in store. It almost felt like I was squeezing into an 8.5 with thin socks on.
With a 9.5 in MC's waiting at a friend's house across the border, it's kind of hard to gauge how that 10 will fit.
I've got my 9.5's in my Trainers, and those feel fine. Hoping the sizing that Fongstarr mentioned a couple posts up is similar with me though.
