AHAR+

ASICS High Abrasion Resistance Rubber (AHAR) is a tough compound used at the heavy contact area of the outsole, for example the heel. It helps to reduce excessive wear. AHAR+ is a lighter version of AHAR.

Biomorphic Fit

DuoMax

DuoMax is an ASICS proprietary system consisting of two or more different density midsole materials, designed to help correct the degree and velocity of pronation.

DuraSponge

DuraSponge is a blown AHAR compound for enhanced cushioning and durability in the forefoot. ASICS High Abrasion Resistance Rubber (AHAR) is a tough compound used at the heavy contact area of the outsole.

I.G.S.

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.

Solyte

Solyte is a proprietary cushioning material used for the midsole of the running shoe. Solyte is lightweight, durable and has excellent bounce-back qualities, providing a comfortable platform to run on. Solyte's impressive shock-absorbing properties help distribute the impact forces of running. As the foot passes through the gait cycle the material compresses to absorb shock and 'bounces back' during propulsion. When the shoe is not in use, it fully decompresses to ensure a full bounce-back feel every time you run. Solyte helps create a smooth, comfortable run, with less shock on the feet and legs, minimising fatigue and reducing the chance of injury.

Space Trusstic System

The Space Trusstic System provides the foot with the right levels of support and flexibility as it moves through the gait cycle. It achieves this through a strategically placed pocket of space between the Trusstic device and the layer of midsole under the foot arch. As the foot moves through the complex motions of running, it makes use of the principle of the windlass mechanism. With every propulsion, the foot acts as a rigid lever, tightening the plantar fascia and heightening the foot arch. The Space Trusstic System works with this natural movement of the foot. As the plantar fascia tightens and presses downward, it can press freely against the midsole which can bend into the space pocket. The hard plastic Trusstic device maintains support while allowing the foot to move efficiently. The result is greater comfort and a more efficient foot function during running.

3M Reflective

3M scotchlite (a registered trademark of the 3M Company) reflective material enhances visibility during low light hours.

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. Automatic Guidance Line thus helps runners to maintain a natural, efficient gait, especially over long distances.
