Under the hood

• Biomorphic Fit Upper

  Stretchy material strategically placed on the upper which reduces bunching when the shoe moves reducing the risk of blisters and irritation.

• I.G.S. (Impact Guidance System)

  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.

• 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.

• 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.

• ComforDry sockliner

  Insole placed inside the shoe which provides cushioning keeping the foot drier and cooler.

• Solyte Midsole Material

  Spongy layer between the sole and upper designed to absorb shock and cushion the foot. Solyte is a lighter material than SpEVA and EVA and features enhanced durability.

• Plus3

  Additional 3mm of cushioning under the heel on women’s models which increases comfort and relieves tension on the Achilles tendon.

• 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.

• 3M Reflectivity

  Special reflective material which enhances visibility in poor light. 3m Scotchlite is a registered trademark of the 3M Company.

• Space Trusstic System

  Plastic bridge under the arch creating a pocket between it and the midsole which improves flexibility and gives the shoe strength and stability.

• AHAR (ASICS High Abrasion Resistant rubber)

  Tough material placed in critical areas of heavy contact on the shoe for exceptional durability.
