An update of a silhouette first seen in the 80s, the adidas ZX 5000 RSPN 80/90/00 Run Thru Time features a super-lightweight upper in red, reinforced with synthetic suede overlays. The shoe sports a sleek, black rendition of the adidas Three-Stripes. An embossed rubber heel cage adds stability in the back, while a Torsion cushioning system allows the forefoot to move independently for a more natural range of motion.
