I don't have my own boots, but when I went 2 weeks ago I rented a pair..
This is how they compared:
Regular Shoes: Size 9, Nike SB's
Boots: 10 (They fit perfectly, I went boarding for 10 hours, no exaggeration, and didn't feel any pain), I think they were "Flow Snowboarding" boots.
just got a pair of Nitro Team TLS in 8.0 and they fit very well. Still getting used to the heal cups they use (got them 2 days ago and have not hit the slopes yet...). But as far as sizing goes, 8.0 was the way to go.
freaking jersey suck, there are no winter sport shops in my area. I will have to go to Dick's or Sport Authority to buy boots.
I wear size 9 shoe but i order a boot(size9) from TruSnow.com . The boots were too tight.
Do you guy have any luck ordering boots online?
