Highlighting neutral tones on a classic running shoe from Nike's early '80s archives is the Nike Air Pegasus 83 'Grey Fog.' A traditional blend of nylon and suede is utilized on the upper in varying shades of grey with a white leather Swoosh. The leather heel tab and woven tongue tag are decorated with Nike Air branding, while underneath is a white foam midsole with encapsulated Nike Air cushioning in the heel and a black waffle-tread rubber outsole.
