Impact Guidance System (I.G.S.®) (RUNNING)
ASICS® Design Philosophy. Employs linked componentry that enhances the foot's natural gait from heel strike to toe-off.

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.
