GEL-Nimbus® 9 $120

What’s New?

Since its inception, each new version of the GEL-Nimbus® series has remained consistent with the original concept of providing superior platform cushioning and comfort.  Then along came the GEL-Nimbus® VI, and with this update a concentration on perfecting upper fit.  The result converted so many runners that the series has subsequently become the industry standard in the cushioning category.  For the GEL-Nimbus® 9, upper comfort will remain an important factor in the overall design. However, this shoe will represent a re-focus on platform comfort and overall ride.

Probably the most noteworthy addition to the platform of the GEL-Nimbus® 9 is the newly engineered heel unit, which features an interpretation of the discreet heel tooling of the GEL-Kinsei®.  This set-up allows each section of the rear-foot to move in a relatively independent manner, creating a greater level of shear deformation and thus, enhanced shock attenuation.  The silicon gel units themselves echo the GEL-Kinsei® as well, with a higher (harder) durometer on the lateral crash pad, which will provide enhanced stability for underpronators.* Also noteworthy is the support added to the waist of the midsole, with a Space TrussticTM unit that is more rigid than in past models, creating improved midfoot support and aiding the transition from foot-flat to propulsion. 

The changes to the upper are subtle but will noticeably enhance fit and comfort.  For instance, the collar length has been shortened slightly, and a new Personal Heel Fit® (PHF) set-up places two layers of memory foam on the medial collar where past versions had only one.  The result is an improved geometry that secures the shoe snugly and comfortably around the heel. In addition, a new one-piece tongue/vamp construction eliminates the need for excessive overlays at the bottom of the eye-stay. Working in concert with the Biomorphic Fit System, this new upper set-up ensures a roomy forefoot that nevertheless secures the foot comfortably on top of the midsole.

*Worth noting is the fact that the density of the silicon gel unit can be manufactured exactly to the durometer specified, unlike standard EVA and other midsole materials,  that have a ‘factor of +/- 4 degrees of hardness that is typically deemed acceptable for production. 

In A Nutshell

The GEL-Nimbus® 9 is ASICS’ top of the line cushioning shoe, featuring a new ‘discreet’ rear-foot design, enhanced midfoot support, and improved upper construction that provides exceptional fit.  The broad, supportive platform is suitable for a range of runners from under-pronators to moderate over-pronators.
