ASICS performance styles speak for themselves, Gel cushioning has been at the forefront of ASICS running styles for decades. In more recent times ASICS performance styles have begun to blur the lines between track and field like their predecessors of the 1980s. Collaborations with up and coming designers and healthy showings on both the front row and the catwalk have propelled the performance styles to the very forefront of what's current. ASICS continues in the same vein with the Gel-Nimbus 21 LS.
