Please note the following about choosing children's shoe sizes: Most children's shoe sizes are factory-standardized and there is no uniform standard (the size of the same shoe may vary depending on the brand). Please measure the foot length. For summer styles, it is recommended to add 0.5cm to the foot length to equal the inside shoe length. For spring and autumn styles and winter styles, it is recommended to add 1cm to the foot length to equal the inside shoe length (the cm indicated after each size is the inside shoe length).
