【Size】16 (16-19cm) Children's high socks equipped with the functions required for winter sports. High heat retention and moisture absorption to reduce unpleasant stuffiness. Supports the vertical arch (arch of the foot). Thin type for good foot feel. Used about twice and outgrown. Personally, although it says 16-19cm, because it's a product with high compression, sizes 16 and 17cm are recommended. Please understand that this is a used item.
