Forefoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the needs of both amateurs and professional athletes. Forefoot GEL reduces the force of the load during push, increasing performance and drastically reducing the risk of injury.

Guidance Line
Guidance Line places a visible groove in the mid and outsole that follows the foot's center of pressure from heel to toe. The result is a more adaptive running platform, creating a smoother transition from heel strike to toe-off with each stride. The Guidance Line thus helps runners to maintain a natural, efficient gait, especially over long distances.

Rearfoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the needs of amateurs and professional athletes alike. Rearfoot GEL offers omni-directional shock absorption, it not only absorbs harmful shock, but helps to stabilize impact forces on the heel.
