NIKE WMNS MAYFLY WOVEN Main color: Black These are ultra-lightweight sneakers. I think brand new, unused items are extremely rare. These shoes have a striking design with a modern upper woven from natural leather. The sole unit uses Phylon material, achieving both cushioning and weight reduction. The woven construction provides excellent design and breathability, making it a new product with superior functionality. Perfect for summer. Unused items are valuable. *Please note that these are women's products. They run 0.5 to 1 size smaller than men's sizes. (Recommended for men who wear 26-26.5cm)
