I knew my kids had small feet, but this thread just proves it. My DS who's 12 finally is up to a 7 1/2 mens, but he was still in a 4 1/2 boys last Christmas.
My soon to be ex wore a 7E. So if you all think it's hard finding kids shoes in that size, try it when they won't OUTGROW the size!
If you really need shoes in that size range, B.A. Mason carries them (a catalog company, but you can buy on-line). But they are pricey.
