Who says you can't improve on a classic?

For 20 years, the GEL-CUMULUS™ shoe model has been a favourite among its loyal fans from performance runners to beginners. But in running there is always room for improvement, which is why the ASICS Institute of Sport Science (ISS) has improved the cushioning and doubled the performance of the fit in areas of the new GEL-CUMULUS™ 21, making running further feel more comfortable.

Designed to cushion the feet over long distances, the GEL-CUMULUS™ 21 shoe combines FLYTEFOAM ™ Propel technology and rear and forefoot GEL™ technology for extra bounce and premium shock absorption to run further. Extra foam in the ankle wrap provides a softer, more cushioned feel.

The development of every ASICS shoe, including its legend models, sees them go through an intensive testing and development cycle in which the new shoe will only be released if the data proves it outperforms the predecessor. For the GEL-CUMULUS™ 21 model the improvement goal was focused on improving the fit and cushioning. They did this by introducing two new features to the GEL-CUMULUS™ 21 shoe model:

  1. The improved discrete eyelet construction for an even better fit with significant improvement on the lateral side and increased performance on the medial side.

2. The combination of FLYTEFOAM™ midsole, softer FLYTEFOAM™ Propel, and Rearfoot GEL™ technology has improved the ride comfort giving runners increased cushioning.

The GEL-CUMULUS™ 21 model will now available from ASICS retail and online stores as well as specialist running outlets.
