adidas Originals revived the classic Flashback runner from the 1970s with this new and improved version updated with Primeknit construction. Released in 2017, the retro-modern silhouette features a lightweight and breathable one-piece upper in bright yellow with tonal Three-Stripes branding. Underfoot, a classic white EVA midsole is topped off with a sawtooth-style outsole in gum rubber.
