This is a set of screw-on cleats for old school Adidas Eddy Merckx cycling shoes. There were several models of Eddys that take these cleats. Two cleats are needed per shoe, which allows you to customize the angle of the shoe vis-a-vis the pedal axle). If you are buying these for your vintage shoes, please check that the screw holes patterns match (Adidas Eddy Merckx modelS, 4 holes per shoe). These cleats are new, in the original, unopened, packaging.
