Adidas Consortium ZX 700, The ZX 700 was originally introduced in the mid 80's as a bio-mechanically correct, high mileage trail/road running shoe. Its multi-purpose rubber outsole studs gripped on soft ground, but retreated into treads on harder surfaces. This version is the winner of the A -ZX competition. It has a unique visual which was not covered by all other designs of the A -ZX Range. The Key highlight detail is how the black midsole blocking extends into the city skyline of Barcelona growing out of the midsole into the white leather upper. The shoe also featues reflective materials.
