A pigskin leather running shoe at 55.00 USD?! Yup. These were part of Nikes Concepts running shoes. They featured pigskin leather, phylon midsole, and combination of BRS 1000 carbon rubber and Phylon for the outsole. They were designed as a sprint training shoe with “a casual shoe appeal”. Ten years later this shoe received the retro treatment but if you want that real ish, the OG is where its at. Take a trip back below!
