I.G.S (Impact Guidance System) is an ASICS design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike through toe-off. Solyte midsole is lighter than standard EVA and SpEVA designed by ASICS. Its responsive nature delivers a supremely cushioned ride and makes it highly durable. Rearfoot forefoot Gel cushioning systems work together to better attenuate impacting shock and allow the foot to move fluidly throughout the gait cycle. Dual-density DuoMax midsole is specifically positioned for running to enhance support and stability. Space Trusstic System mid-foot stabilizer creates a pocket between the Trusstic System unit and the midsole, promoting more controlled midsole deformation, as well as more efficient foot function. Propulsion Trusstic mimics connective tissues in the foot by creating tension as the foot enters the propulsion phase. Guidance Line technology employs a vertical flex groove that decouples the tooling along the line of progression for maximum stride efficiency. DuraSponge forefoot outsole material is comprised of a blown AHAR rubber for superior cushioning and long-lasting wear. AHAR (ASICS High Abrasion Rubber) is known for its supreme durability and is strategically placed throughout high-wear areas of the outsole.
