Asics technologies include:

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.
FULL LENGTH GUIDANCE LINE - Vertical flex groove in the sole running from heel to toe which encourages a more efficient running style.
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.
HEEL CLUTCHING SYSTEM - Lightweight heel counter on the outside of the upper which provides improved support and fitting around the heel.
DISCRETE HEEL UNIT - Dual density GEL Cushioning in the heel which provides an improved level of shock dampening and stability within the shoe.
PROPULSION TRUSSTIC SYSTEM - Plastic bridge under the arch which mimics the connective tissue in the foot by creating tension as the foot moves through each step.
ASYMMETRICAL LACING DESIGN - Lacing which follows the natural curve of the foot giving a better fit and reducing the potential for irritation.
CUPROTHERMO - Metallic film in the upper which retains heat in cold weather and releases heat in warm weather.
BIOMORPHIC FIT UPPER - Stretchy material strategically placed on the upper which reduces bunching when the shoe moves reducing the risk of blisters and irritation.
