The City Marathon PT lay hidden for almost a third of a century in the attic of a former Technical Director of adidas, until last year when the prototype was uncovered while the 90-year-old was moving house. The classic shoe design utilizes adidas’ patented Dellinger Web technology, which disperses impact shock to cushion your stride when your foot hits the ground and, in turn, performs like a trampoline to add spring to every step you take.

For FW13 we’ve re-produced this vintage silhouette with a trio of classic colourways: Berlin, Chicago and New York. The shoes also give a subtle nod to marathon racing by incorporating the distance it takes to complete a marathon course, 42.195km, as part of the branding.

Look for the adidas Originals FW13 “City Marathon” Pack to release on September 1st, 2013, retailed for $110 to select adidas Originals accounts, including adidas.com/originals.
