adidas Terrex Mid Gtx K Children's Outdoor Shoes Ie6079 Black

Hello! If your son wears size 30 in Superstar, according to the adidas children's size chart, this corresponds to a foot length of approximately 18.7–19 cm. In the Terrex Mid GTX K models, the fit is a little tighter, so it is more comfortable to go one size larger. Therefore, my suggestion: If you have a wide foot structure, you can also prefer size 32 if you want, but mostly 31 is sufficient. If you need help with something different, we are always here for you as KoraySpor.
