15. Nike Terra T/C

Year: 1981

This running flat brought us Phylon — the foam with superior shock absorbing properties that offered neither an excess of cushioning, nor too little, that allowed for some molding that was more anatomically accurate than ever before. Variable width lacing and a reinforced rear added bulk, but a 6.7 oz weight was pretty minimal. Later on, the Eagle would clock in even lighter and 1983's Nike Equator would implement the mysterious cobra pad, building up their shoes. All three models remain iconic, but the Terra T/C's black. white and red colorway is key to the shoe's appeal.
