Upper: Optional speed laces are included for a quick transition from bike to run. Padded tongue and heel collar for maximum comfort. Glow-in-the-dark elements on the heel and toe for added style and visibility. Open mesh upper enhances ventilation helping tri-athlete’s feet dry quickly and stay dry. Soft liner materials and limited interior stitching allow the shoe to be worn barefoot.

Midsole: Solyte® midsole material is a lighter weight midsole compound than ASICS’ standard EVA and SpEVA®. Space Trusstic System® midfoot stabilizer creates a pocket between the Trusstic System® device and the midsole allowing for controlled midsole deformation and more efficient function. Guidance Line® vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. Impact Guidance System (I.G.S.®) design philosophy employs linked componentry that enhances the foot’s natural gait from heel strike to toe-off. Heel and forefoot GEL® cushioning systems attenuate shock during impact and toe-off phases and allow movement in multiple planes as the foot transitions through the gait cycle. DuoMax® support system dual density midsole is positioned to enhance support and stability. Removable, perforated sockliner helps drain moisture. Dual density Solyte® lasting.

21.5mm heel midsole height, 11.5mm forefoot midsole height.

Outsole: AHAR® ASICS High Abrasion Rubber is placed in critical areas of the outsole for exceptional durability. DuraSponge® outsole uses a blown AHAR® rubber compound for enhanced cushioning and durability in the forefoot.
