Thank you for viewing! ^ ^ This item was purchased from SHEIN. My daughter intended to wear these, but they weren't what she expected, so she only tried them on. For reference, my daughter is 20 years old. Her shoe size is 24cm. She said the fit feels like compression socks. Although these are for adults, they should be fine for upper elementary or junior high school students as well. Please understand that this item has been stored at home by a private individual. Thank you for your understanding!
