The ASICS GEL-NIMBUS 21 is a good all-rounder shoe for daily training runs. If you want a comfortable running shoe, the GEL-NIMBUS 21 is the perfect choice for you. Its GEL cushioning means that you can wear this shoe even with sore feet. I wouldn't think twice about wearing this model for a marathon either. Jan Lau - Keller Sports Pro


The ASICS GEL-NIMBUS has been around for over twenty years. With this new version of the running shoe, ASICS has taken the model to a whole new level. The innovative midsole construction with FlyteFoam Propel offers superb cushioning to the forefoot and gives you extra forward drive. Combine this with the perfect fit and top comfort and your next personal best is just a matter of time.



The sole of the shoe sports impact-absorbing SpEVA 45 Lasting foam that cushions every move you make. Apart from this, ASICS has added two different layers of FlyteFoam cushioning to this model too - the upper layer is made of FlyteFoam Propel and the lower layer is FlyteFoam Lyte. Together, they deliver the ultimate comfort. The roomy toe box and moulded EVA insole add to this comfort while also ensuring your feet stay dry and enjoy full freedom of movement.


The newly developed mesh offers additional breathability and support. This model also boasts an external Clutch Counter system that delivers maximum support to the heel. The Ortholite foam in the collar of the shoe delivers efficient moisture management, while the AHAR outsole improves grip on wet surfaces and provides full lateral contact. The overlay is for instep support.
