Nike unisex special edition standard fit black and grey pig leather mesh and suede low top retro running sneaker. First released in 2003, the Nike Air Zoom Spiridon Cage 2 designed by sportswear industry craftsman Steven Smith, was originally intended for the Japanese market. Dan Jones, the head of the running category at Nike that Smith worked in at the time, later suggested he make a slight design change by adding a piece of rubber to the front of the shoe in order to make the silhouette more palatable to a worldwide audience. Smith kept the forefoot of the shoe relatively open allowing additional flexibility by using open-screen mesh on its upper for ventilation and a combination of Phyllite and rubber on the outsole. Features a full length foam midsole and a caged Zoom Air unit providing efficient energy response and a modern look.
