IMPACT GUIDANCE SYSTEM (I.G.S.) - ASICS Design Philosophy. Employs linked componentry that enhances the foots natural gait from heel strike to toe-off.
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.
COMFORDRY SOCKLINER - Provides cushioning performance and anti-microbial properties for a cooler drier healthier environment.
Gender Specific Forefoot Cushioning - A top layer of injected solyte provides a cushioned platform fell 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.
