NK-AJ4 Retro Black/Red/Gray 36~47.5 basketball

The NK-AJ4 Retro in Black/Red/Gray is a timeless icon that bridges the gap between basketball heritage and streetwear culture. Originally designed by Tinker Hatfield in 1989, this silhouette remains a staple for sneakerheads and casual wearers alike. The striking colorway—featuring a black base, red accents, and gray detailing—pays homage to the classic 'Bred' aesthetic while adding a modern twist with the gray hits on the midsole and eyelets.
