Biomorphic Fit

Biomorphic Fit technology allows the upper of the shoe to move in harmony with the foot, giving more comfort while in motion. This fit means the shoe material does not bunch, reducing the risk of blisters or irritation.

3M Reflective

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

Soft Top DuoMax

Soft Top Duomax is a softer top layer of the Duomax midsole. Together with the Gender Specific Space Trusstic, Soft Top Duomax accommodates for fluctuations in women's hormonal levels which cause the foot arches to be lowered, creating more pressure on the plantar fascia. By using a lower-density material, Soft Top Duomax provides a more comfortable transition from heel strike to toe-off without sacrificing stability.

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.

Gender Specific Forefoot Cushioning

Gender Specific Forefoot Cushioning refers to the inclusion of specially formulated Solyte material in the forefoot. The material's density is reduced, allowing the female foot to compress it sufficiently and benefit fully from the bounce-back qualities of Solyte. Traditionally, women's running shoes contained cushioning material of the same density as men's. However, as women are usually lighter than men, the female foot would not fully compress the material, resulting in a less than optimal ride. Gender Specific Forefoot Cushioning addresses this issue and provides women with a more comfortable and responsive ride. The cushioning material, located under the ball of the foot and extending across the width of the shoe, also acts as an efficient shock absorber.

Plus3

Plus3 refers to a 3mm raise of the heel compared to the forefoot. The effect this has is to reduce strain on the Achilles tendon. As women's hormonal levels fluctuate during their monthly cycle, the Achilles tendon becomes lax or stretches, increasing the potential for injury. Plus3 reduces the load and tension on the Achilles tendon and reduces the risk of injuries.

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.
