Some brands have varied widths as well...if that helps at all.

I have seen children around here in nice cycling shoes, have you looked into childrens sizing?

I had to send Sidi a letter asking if they had a crash replacement policy (hubby had to have his brand new shoe (a week old ) CUT off of his foot in a mtb accident.) They were very nice and prompt with a reply...call them and any other brand you have interest in. I personally like Shimano cause I have a fat, short foot and they fit nice! (size 36) I wear a 6 in a running shoe

Good Luck
