The Fragment Design x Air Trainer 1 Mid SP 'Gym Red' is a special edition collaboration released in September 2015, in partnership with Hiroshi Fujiwara's Fragment Design. This limited edition sneaker features a premium leather upper in a striking tonal Gym Red color, which stands out due to its perforated detailing on the toe box and medial panel. Additionally, the shoe incorporates grey accents on the strap branding and top eyelets, as well as a debossed Fragment Design logo on the lateral ankle and a gold NikeCourt hang tag. The tonal upper is complemented by a clean white outsole, which showcases a subtle Volt Nike insert for added contrast.
