It's amazing how many of ASICS' elite Impact Guidance System (I.G.S.®) components we've packed into a 10 oz. shoe. This go-fast addition to the Speed Collection fits and rides like a racer, but with a substantial feel and support.

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.
Guidance Line™
Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
Discrete Eyelets
Independently placed eyelets disburse lace tension, creating a customized fitting environment and enhanced upper comfort.
Propulsion Trusstic®
Mimics connective tissue in the foot by creating tension as foot enters propulsion stage.
Space Trusstic System®
This midfoot stabilizer creates a pocket between the Trusstic System® device and the midsole, allowing for controlled midsole deformation and more efficient foot function.
Biomorphic Fit ® Upper
Stretch material strategically placed on the upper helps to reduce buckling and the potential for irritation.
Asymmetrical Lacing Design
An anatomically correct lacing environment that reduces potential for irritation and provides improved comfort and fit.
Slip Lasting
For lightweight and flexibility. Upper is wrapped and stitched before it is glued to the midsole.
