A symbiosis of Saucony icons. The Saucony SILO Grid X Ultra sees Grid upper technology fuse with the Xodus Ultra 4's elite-level trail tooling and the bespoke Xodus line Vibram® MegaGrip outsole. A full-grain leather lock-in strap closure sits atop a breathable spacer mesh and an engineered knit collar construction upper, durable scratch rubber overlays, and a compression molded PWRRUN rim and PWRRUN PB core performance midsole. A harmonious fusion of Saucony's iconic design codes.
