These are Nike Air Force 1 Ultra Flyknit shoes purchased in 2016. They are used, with minimal damage, having been worn about 10 times. The soles also show only slight wear. I believe these are one of the earliest Flyknit shoes released by Nike. Released in January 2016, retail price in Japan was 21,600 yen. Size: 9.5 inches / 28cm Style Code: 817420-600 Color: University Red/Black Box: Not included The "AIR FORCE 1," which debuted in 1982, has long been a street staple, closely linked to the culture of its time, transcending the boundaries of basketball shoes. This is the "AF1 ULTRA FLYKNIT MID," which updates the upper of the original model with Flyknit panels, creating a three-dimensional design with enhanced breathability and elasticity. It incorporates an AIR-SOLE unit in the heel of the lightweight injection-molded midsole, preserving the form of the "AIR FORCE 1" while achieving a 50% reduction in weight compared to the original model.
