So I got my Infrareds last Friday, and went a .5 size up. I've had a couple chances to wear them around for normal casual use.
I must say, they look fantastic. The color is eye popping, and certainly a head turner for sure.
That being said, I kinda wish I could have tried them on first. I was going off of the many comments here, reviews online, even Footlocker I think posted something to the effect of they recommend going a half size bigger than you normally would.
They are a little tight to get into, but honestly I think i could have fit my normal size 11. They feel fine, and I should be able to manage going forward, but kind of want to see how an 11 feels now.
