Celebrate 15 years of Ronnie Fieg’s legacy with the Kith x ASICS GEL-Kayano 12.1 "Quartz." Released in January 2026, this "tier-exclusive" masterpiece serves as a reward for the Quartz tier of Kith’s Loyalty Program. This hybrid silhouette features a premium, open-cell mesh upper in a soft, dusty pink hue, reinforced by transparent TPU overlays that provide a structural, futuristic edge. With "Just Us" and Loyalty-specific branding on the insoles, this pair is a powerful blend of ASICS performance heritage and Kith’s unparalleled eye for lifestyle luxury.
