Impact Guidance System (I.G.S®): ASICS® design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off. FluidRide®: FluidRide® provides the ultimate combination of bounce back and cushioning properties with reduced weight and exceptional durability. Rearfoot and Forefoot GEL® Cushioning Systems: Attenuates shock during impact and toe-off phases and allows movement in multiple planes as the foot transitions through the gait cycle. Guidance Trusstic System®: This Trusstic System® integrates Guidance Line® construction for enhanced gait efficiency while providing midfoot structural integrity. Guidance Line®: Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. Seamless Construction: The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams. Discrete Eyelets: Independently placed eyelets disburse lace tension creating a customized fitting environment and enhanced upper comfort. ComforDry™ Sockliner: Provides cushioning performance and anti-odor properties for a cooler drier healthier environment. Gender-Specific Cushioning: Women's models feature a lower-density top layer in the midsole allowing female athletes to better enjoy the benefits of midsole compression.
