Just a quick note, for the Extero Jr’s you may have to go up a full size on these little guys shoes. I have a son with a wide foot and we brought them home for my kids that measure a 11.0 k and 11.5k – normally you may try to get into an 11.0 and a 12.0k for these two guys. My son that has an 11.0k foot had to go up to the 12.0k because of the width in his shoe. And my son who is an 11.5k had to go up to a 12.0 k (which is as expected).
The reason you have to size up a full size maybe even a size and half is the velcroe straps on the shoes are not wide enough to work with a wider foot or a foot with a higher instep. You may want to go with a tied wrestling shoe if your son or daughter has a wide foot.

A Good Read…
Very helpful info thanks…
