Inspired by the heritage of the original GEL-KAYANO TRAINER, the GEL-KAYANO TRAINER 21 blends archived aesthetics with performance capabilities that have been perfected by ASICS over the years. The hybrid silhouette retains the MONO-SOCK design from the OG ‘90s runner and replaces the standard upper materials with premium fabrics that include pigskin and nubuck to deliver a more luxe overall look. Tooling from the 2014 GEL-KAYANO 21 is implemented throughout on the new trainer, as GEL technology cushioning in the heel and forefoot notably enhances the pair’s performance functionality.
