The Royal Blue Nike Air Foamposite One is by far the most popular, starting with its original release back in 1997. Some images have surfaced of a sample pair being dubbed Blue Carbon.
The Nike Air Foamposite One Blue Carbon Fiber sample features blue stitching around the Nike logos and most importantly a blue and black checkered carbon fiber plate.
We do wonder why Nike decided to scrap this pair, maybe we will see a future release? Which pair do you like better, original or sample?
