IMPACT GUIDANCE SYSTEM (I.G.S.) - ASICS Design Philosophy. Employs linked componentry that enhances natural gait from heel strike to toe-off.
FULL LENGTH GUIDANCE LINE - Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
HEEL CLUTCHING SYSTEM - Exoskeletal heel counter provides improved support and creates improved heel fitting environment.
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.
PROPULSION TRUSSTIC - Mimics connective tissue in the foot by creating tension as the foot enters propulsion stage.
ASYMMETRIC LACING SYSTEM - An anatomically correct lacing environment that reduces potential for irritation and provides improved comfort and fit.
CUPROTHERMO - Metallic film in the upper that retains heat in cold weather and releases heat in warm weather.
