Grid SD

Launched originally in 91, the Grid SD marked a unique balance between shock absorption and stability for runners. Reworked in modern form this season, the shoe features a Wolverine Silkee Suede upper with perforations and a molded forefoot, quarter straps and reflective material at the heel. The midsole also includes Saucony’s cushioning system called G.R.I.D. (Ground Reaction Inertia Device) and the sole is fitted with an outer triangular lug system.
