The running shoe introduces a window design into the middle part and adopts an integrated midsole to create a 360° heat dissipation system, avoiding stuffiness while ensuring light weight, shock absorption and stable support. Considering the development of children’s feet, it incorporates a wide-width last to provide sufficient room for the toes to freely move. In addition, the twist-lock design frees children from trouble of tying laces. As for appearance design, the product, by virtue of its streamlined shape, healing colors and glossy & matte PP films, features a unique stylish aesthetic.
