The Stray Rats x NB 991 Made in England 'Purple Green' adds neon accents to a performance running shoe originally released in 2001. A product of NB's Flimby factory, the premium construction combines a purple pigskin suede base with brown and beige nubuck overlays. Reflective details appear on the vamp and heel, while a bright green 'N' logo stands out on the side panel. The Stray Rats streetwear brand makes its mark with embroidered '//stray' lettering on the lateral forefoot. The shoe features a violet and gray ABZORB midsole.
