Revealed in October 2019, the ASICS Gel Nimbus 21 from the 'Midnight Blue' pack evokes the look of the night sky. The sneaker is kitted out in engineered mesh featuring no-sew TPU overlays, an external heel cup and fused logo stripes. Signature branding remains on the tongue and counter. While the white FlyteFoam midsole helps improve propulsion, the high-abrasion rubber outsole enhances traction.
