For people looking for sizing info, I have narrow feet and usually wear Bauer Vapor x2.9 R size 7, or Mission D size 8. All my skates are roller, not ice, though I don't think that matters for fit.
I tried both True TF9 size 7 and 7.5. The size 7 fit as a very snug performance fit with toes touching the front, but I play recreationally for multiple hours and prefer a little room in my toebox for comfort. The 7.5 fits perfectly for me.
The in-box instructions say to bake at 180 for 6 minutes; I ended up doing 10 minutes on each skate (after checking the boot softness every minute). I used the saran-wrap method at home to get a good wrap.
There is some weird cushioning in the toebox of the 7.5 which I stopped noticing after my first skate.
Notably the heel area is fantastic. Heel is locked in & I'm not getting the usual raw discomfort/blistering around the Bauer Bump area that my Vapors used to give me. I am particularly impressed by the heel lock and comfort, given my narrow heel.
The skates are very difficult to get into and out of, but once they're on, they feel great. I'm hoping my feet just get used to this.
The included "Custom arch system" feels crummy. I have high arches and tried using the included inserts but found them uncomfortable and tossed em after my first skate. The stock insoles are fine.
As I break in the skates, I am hoping they do not open up since the fit is just right; time will tell.
