I.G.S® (IMPACT GUIDANCE SYSTEM) TECHNOLOGY
ASICS design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.
FLYTEFOAM® PROPEL TECHNOLOGY
FLYTEFOAM® MIDSOLE TECHNOLOGY
Our FlyteFoam technology provides exceptional bounce back and responsiveness no matter the distance, utilizing organic super fibers to help reduce packing out that traditionally happens with softer, low density foams.
ASICS FluidRide® midsole provides the ultimate combination of bounce back and cushioning properties with reduced weight and exceptional durability.
REARFOOT AND FOREFOOT GEL® TECHNOLOGY CUSHIONING SYSTEM
Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle.
GUIDANCE LINE® MIDSOLE TECHNOLOGY
Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams.
Independently placed eyelets disperse lace tension, creating a customized fitting environment and enhanced upper comfort.
Acronym for ASICS High Abrasion Rubber. Placed in critical areas of the outsole for exceptional durability.
SPEVAFOAM™ 45 LASTING
