Under the hood

• 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.

• 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. Automatic Guidance Line thus helps runners to maintain a natural, efficient gait, especially over long distances.

• AHAR

  ASICS High Abrasion Resistance Rubber (AHAR) is a tough compund used at the heavy contact area of the outsole, for example the heel. It helps to reduce excessive wear.

• Gender Specific Forefoot Cushioning

  Gender Specific Forefoot Cushioning refers to the inclusion of specially formulated Solyte material in the forefoot of the female shoe. Since this material is less dense than the traditional material it offers greater impact absorption and more bounce for female runners.

• Space Trusstic

  The Space Trusstic System is an advanced system that creates a pocket between the Trusstic System device and the midsole, allowing for greater midsole deformation and more efficient foot function.

• DuraSponge

  DuraSponge is a blown AHAR compound for enhanced cushioning and durability in the forefoot. ASICS High Abrasion Resistance Rubber (AHAR) is a tough compound used at the heavy contact area of the outsole.

• ComforDry Sockliner

  The ComforDry Sockliner provides the optimum cushioning performance that creates a cooler, drier and healthier shoe environment.

• Solyte

  Solyte is a proprietary cushioning material that provides an exceptionally lightweight midsole with excellent bounce-back and durability.
