A perfect blend of retro aesthetic and modern technology, the 1906R takes its design cues from running styles of the 2000s. Open-holed mesh covers the base, while silver and grey leather and synthetic overlays cross along the uppers for a vintage sports appeal. Below, the ABZORB midsole offers impact absorption, changing underfoot cushioning for the better, while the N-ergy outsole and Stability Web technology provide a secure, responsive ride. - M1906RRD, Textile & Synthetic Upper/Synthetic Sole.
