The Asics Gel Cumulus 13 running shoe is designed to provide runners with the optimal blend of cushioning and stability.

• The Impact Guidance System (IGS) is an ASICS design philosophy. It aims to make shoe components from rear to midfoot and forefoot to work together effectively to allow the body to perform in a natural manner. ASICS designers strive to compliment, not correct, how the legs and feet move. This works in hand with the shoe's Guidance Line; a vertical flex groove that decouples the tooling along the line of progression for enhanced gait efficiency.
• The ComforDry Sockliner provides cushioning performance and anti-microbial properties for a cooler, drier and healthier environment.
• Solyte is a proprietary cushioning material that provides an exceptionally lightweight midsole with excellent bounce-back and durability.
• Rearfoot GEL provides cushioning in all directions absorbs impact forces and helps to stabilise the foot during heel contact. The GEL in the heel is left exposed in this case.
• A top layer of injected Solyte provides a cushioned platform feel in the forefoot that result in gender specific cushioning.
