Exhibiting a bespoke design approach, the HS1-S TARTHER™ BLAST sneaker features a hybrid formation that connects components from our current and heritage running catalogs. A racing aesthetic worn by marathon runners in the 80s is synergized with a retro look that's reworked with recycled materials throughout the upper. The "Retro Futurism" concept continues onto the midsole, which features the FLYTEFOAM® Blast tooling from our performance running line—supplying advanced cushioning and a modern shape.
