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.
Guidance Line™
Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
Discrete Heel Unit
Takes the Impact Guidance System (I.G.S.®) to a new level by creating our highest degree of shock attenuation and stability.
Gender Specific Forefoot Cushioning
A top layer of injected Solyte® provides a cushioned platform feel in the forefoot. Women's models feature a lower density for improved cushioning and forefoot comfort.
Gender Specific Space Trusstic System®
Recognizes the normal periodic changes in the shape of the woman's arch and provides for the controlled deformation of the arch into the space within the system.
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.
