Upper: Padded air mesh tongue maximizes ventilation and comfort. Discrete eyelets are independently placed to disburse lace tension, creating a customized fitting environment and enhanced upper comfort. Biomorphic fit provides superior fit and function while decreasing the potential for irritation by strategically placing stretch material on the upper. Asymmetrical lacing enhances Biomorphic Fit™ by conforming to the bony architecture of the foot for an enhanced fit with less irritation. P.H.F.® heel collar molds to athletes heel, creating a personalized fit. All stitching has been removed from the heel collar for a better fit with less irritation. 3M Reflective Material enhances visibility during low light hours increasing safety.

Midsole: Guidance Line™ vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. Forefoot and rearfoot GEL cushioning systems are strategically placed to absorb shock. Impact Guidance System (I.G.S.®) links components to enhance the foot's natural gait from heel strike to toe off. Solyte™ midsole is a lighter material than both ASICS' standard EVA and SpEVA® with improved cushioning and durability. A top layer of injected Solyte® provides a cushioned platform feel in the forefoot. Women's models feature gender specific cushioning with a lower density for improved cushioning and forefoot comfort. Solyte™ 45 Last Construction enhances try-on comfort and long-lasting feel by employing ASICS' new proprietary Soltye™ Midsole Material. Gender specific Space Trusstic System® recognizes the normal periodic changes in the shape of the woman's arch and provides for the controlled deformation of the arch into the space within the system. ComforDry™ insole provides the optimum cushioning performance system that creates a cooler, drier, healthier shoe environment.

24mm heel height, 14mm forefoot height.

Outsole: AHAR® heel plug, ASICS High Abrasion Resistant rubber, provides increased durability in critical areas of the heel. DuraSponge® is a blown AHAR® rubber compound that enhances cushioning and durability in the forefoot.
