The unisex Asics x Kiko Kostadinov UB9-S Gel-Kayano 20 low top sneakers in crystal pink and classic red updates a retro design with modern materials and components, designed by someone other than Toshikazu Kayano for the first time. This reinvigorates the brand's signature values and improves performance, preserving the original midsole and GEL® technology cushioning, while enhancing the fit of the leather and mesh upper from 2008.
