Sole

Solyte™ midsole is a lighter material than both ASICS' standard EVA or SpEVA^® with improved cushioning and durability. Solyte™ 45 Last Construction enhances try-on comfort and long-lasting feel by employing ASICS' new proprietary Soltye™ Midsole Material. Impact Guidance System (I.G.S.^®) links components to enhance the foot's natural gait from heel strike to toe off. Space Trusstic System™ is an advanced system that creates a pocket between the Trusstic System™ device and midsole, allowing for greater midsole deformation and more efficient foot function. ComforDry™ insole provides the optimum cushioning performance system that creates a cooler, drier, healthier shoe environment. The "Twist" GEL^® Cushioning System enhances shock attenuation and allows for improved toe-off position. The 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.
