A racing flat designed to meet the needs of triathletes. Designed to be worn barefoot, with an open-mesh upper and perforated sockliner to keep feet cool. Speed laces save time in transition, and come in either standard or elastic form.

• Impact Guidance System (I.G.S.®)
  ASICS® design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.
• Elastic Laces
  A classic triathlon feature allowing a runner to put the shoe on quickly, easily, and securely.
• Propulsion Trusstic®
  Mimics connective tissue in the foot by creating tension as foot enters propulsion stage.
• Space Trusstic System®
  This midfoot stabilizer creates a pocket between the Trusstic System® device and the midsole, allowing for controlled midsole deformation and more efficient foot function.
• Dual Density Solyte® Lasting
  Employs different densities of Solyte® lasting material in heel and forefoot for improved comfort.
• Guidance Line™
  Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
