Over twenty years ago, Saucony introduced a technology called the G.R.I.D. System (Ground Reaction Inertia Device) that would evolve over the next two decades. The system was designed to simultaneously absorb shock and control mediolateral motion. Three years later, we created the G.R.I.D. 8000 CL. The update includes blended composite Hytrel filaments molded in an interlocking configuration. Designed to work with the midsole in reducing shock and enhancing stability.The three colorways each feature soft Wolverine Silkee Suede and synthetic mesh uppers. The silhouette features “marshmallowy” EVA sole unit that provides incredible underfoot cushioning with every step.
