After all this talk about the fit of the air jordans of late as well as some conversations I have had with friends about shoe sizes and what not, the question came up as to how a shoe should fit. I have heard everything from half a thumbnail when your foot is pressed all the way to the back to half an inch in the front and 1/8th of an inch in back. I have also heard not to adhere to the "space" theory because once the shoe breaks in, it will be too big. I have worn a size 10 most of my life but people are saying I wear my shoes too big. what is your guys' input and how do you know if your shoe fits? Mods, please move if in wrong section, I was not really sure where to post.
