Always take your child or person to the boot barn and measure before you purchase - these fit fantastically, but they would not have fit as expected if I had not previously tried on a pair that was way too expensive at the boot barn, and then come to Amazon with the right size in mind, and then purchased the size I needed.  I mean, boots don't fit like other shoes so it is important to know your size for what you are looking for before you just run off buying them up by the truck loads.
