Under the hood

• 3M Reflective

  3M scotchlite (a registered trademark of the 3M Company) reflective material enhances visibility during low light hours.

• I.G.S.

  The Impact Guidance System (IGS) 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.

• Solyte

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

• Soft Top DuoMax

  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.

• 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.

• Biomorphic Fit

  Biomorphic Fit technology allows the upper of the shoe to move in harmony with the foot, giving more comfort while in motion. This fit means the shoe material does not bunch, reducing the risk of blisters or irritation.

• AHAR+

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

• ComforDry sockliner

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