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.

• AHAR (ASICS High Abrasion Resistant rubber)

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

• Biomorphic Cut

  Biomorphic Cut is a cutting and seaming process for fabrics based on extensive research on how the body moves. It allows for maximum freedom of movement.

• ComforDry sockliner

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

• Soft Top DuoMax Support System

  Soft Top Duomax is a softer top layer of the Duomax midsole. Together with the Gender Specific Space Trusstic, Soft Top Duomax accommodates for fluctuations in women's hormonal levels which cause the foot arches to be lowered, creating more pressure on the plantar fascia. By using a lower-density material, Soft Top Duomax provides a more comfortable transition from heel strike to toe-off without sacrificing stability.

• 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.

• 3M Reflectivity

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

• 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.

• 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.
