Originally launched in 1999, the Asics Gel-Kayano 5 OG made a triumphant return in 2018 with this ‘Stone Grey’ colorway. Like the original, it features a bulky build with heavy overlays and tiger stripe branding in grey and black with multicolor accents. Underfoot, it retains the same robust tooling and GEL technology highlighted in red through a window at the heel.
