Forefoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the  needs of both amateurs and professional athletes. Forefoot GEL reduces the  force of the load during push, increasing performance and drastically  reducing the risk of injury.
Guidance Line
Guidance Line places a visible groove in the mid and outsole that  follows the foot's center of pressure from heel to toe. The result is a  more adaptive running platform, creating a smoother transition from heel  strike to toe-off with each stride. The Guidance Line thus helps  runners to maintain a natural, efficient gait, especially over long  distances.
I.G.S.
The Impact Guidance System (I.G.S.) is an Asics design philosophy. It  aims to make shoe components from rear to midfoot and forefoot to work  together effectively to allow the body to perform in a natural manner.  Asics designers strive to compliment, not correct, how the legs and feet  move.
Rearfoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the  needs of amateurs and professional athletes alike. Rearfoot GEL offers  omni-directional shock absorption, it not only absorbs harmful shock, but helps to stabilize impact forces on the heel.
AHAR+
Highly abrasion-resistant rubber, strategically placed in areas of greatest impact, such as the heel, to increase the durability and protection of the sole.
FlyteFoam
FlyteFoam is a very lightweight and durable new generation cushioning. The innovative formula of the foam is characterized by a combination of materials that increase foot release with a delicate push.
FlyteFoam Propel
FlyteFoam Propel is the lightest foam on the market today, patented to guarantee, increased comfort in the rest phase, to a new generation of shoes. Placed in the midsole allowing extraordinary durability thanks to nanofibers that make up the entire shoe structure.
LITETRUSS
 LITETRUSS is an Asics pronation correction system, born from the fusion of DUO Max and the Trusstic System, which supports every step thanks to a progressive density compound.
