Asics Gel is the brand's proprietary silicone-based shock-absorbing cushioning technology, introduced in 1986. Gel consists of liquid silicone encapsulated within dedicated midsole chambers — visible through exposed windows on many Asics silhouettes. The technology absorbs impact energy and reduces foot fatigue during extended running sessions.
The Gel innovation
Before Gel, running shoe cushioning relied entirely on EVA foam — which compressed over time and lost responsiveness. Asics's Gel formulation maintained its cushioning properties over thousands of miles and across temperature extremes. The visible Gel windows (heel and forefoot) have become as iconic as the brand itself.
