Because the size of all children’s shoes is different, when you order children’s shoes, you should according to our size and inner length. American size is not standard, just convenient for you to order. Comfortable inner sole length is foot length + 1cm. If you don’t know how to choose the size, please tell us your child’s foot length, we will choose for you. And because the mail delivery time is long and the children grow up fast, please choose bigger shoes for the children. All shoes are shipped in bubble bags, not boxes!!!!
