NK-AJ4 RM white/black/sail EU 36-46 casual
The NK-AJ4 RM in white, black, and sail is a masterclass in blending heritage with modern versatility. This iteration takes the iconic silhouette that defined the late '80s and reimagines it for today's lifestyle wear, offering a clean, tonal palette that pairs effortlessly with everything from tailored trousers to distressed denim.





Design & Materials

Every seam on the NK-AJ4 RM white/black/sail sits flat against the foot, which means fewer hot spots during long days on your feet.
Underfoot, a cushioned midsole absorbs impact and returns a little bounce, which is exactly what you want from a daily lifestyle sneaker.
