I.G.S. (IMPACT GUIDANCE SYSTEM) - ASICS design philosophy in which the individual components of the shoe work together resulting in a more comfortable step and an improved gait.
REARFOOT AND FOREFOOT GEL CUSHIONING SYSTEMS - Silicone-based material placed in critical areas of the sole which dampens shock when the foot hits the ground allowing for a smooth movement through the step and reducing the risk of injury.
SOLYTE MIDSOLE MATERIAL - Spongy layer between the sole and upper designed to absorb shock and cushion the foot. Solyte is a lighter material than SpEVA and EVA and features enhanced durability.
HEEL CLUTCHING SYSTEM - Lightweight heel counter on the outside of the upper which provides improved support and fitting around the heel. Wet Grip Rubber - Sole material made from a special blend of organic and non-organic components designed to enhance traction even on wet surfaces.

COMFORDRY SOCKLINER - Insole placed inside the shoe which provides cushioning keeping the foot drier and cooler.
BIOMORPHIC FIT UPPER - Stretchy material strategically placed on the upper which reduces bunching when the shoe moves reducing the risk of blisters and irritation.
