Nylon/suede upper. EVA midsole. Rubber outsole. True sizing. Originally designed for track and field hijinks back in the 70s, the hallowed adidas TRX Vintage is back, souped-up for 21st century sojourns. They’ve still got that el classico runner design, but proceedings are a bit more comfortable thanks to those grippy rubber outsoles and dangerously comfortable EVA midsole numbers.
