GRAIL Nike Air Foamposite 1 Prototypes with some crazy textured surface to the foam skin, Solid (not clear) rubber outsole, BIG mesh hole cutouts (which appear to have been a precursor to the oval mesh cutout windows that later came on the Flightposite), and some handwriting on medial side (See pic 5).
I've Never seen another pair in the world like these and they could very well be the only pair in existence.
