These are black, slip-on style shoes from NIKE. They are the Flex Runner 2 model. Made of mesh material, they are breathable and I think they are easy to wear. The retail price is 4,199 yen (tax included). I had forgotten I bought them, and quickly started using them, but they became too small after about a week of use... Therefore, I don't think they have been used that much, but there is some dirt on the white part of the sole at the toes, the soles, and the sides of the shoes. - Brand: NIKE - Color: Black - Features: "JUST DO IT" logo - Design: Slip-on style - Material: Mesh and synthetic materials Feel free to ask any questions about the product♪
