I am selling the hard-to-find Adidas Adizero Prime X 3 Strung. This is the "illegal" model from Adidas (it exceeds the 40mm stack height allowed for pros), loved by runners all over the world for its incredible energy return and total protection over long distances. Absolutely perfect condition, like new. They have been used for two 10 km runs. As can be seen from the detailed photos, the Continental sole is pristine, the Lightstrike Pro foam has no compression creases, and the innovative Strung upper is immaculate.
