These are Mizuno short tights for track and field. They were worn as a uniform, so they can be used in actual competitions. I am selling them because I received them from an acquaintance and don't wear them. They have been worn by my acquaintance, so there is a feeling of use, but I don't think it will affect the competition. The size is L, and it fits well for someone who is 160cm tall. Instant purchase is OK. Mizuno MIZUNO Blue Short Tights Short Tights Uniform Gender: Unisex
