The TARTHEREDGE 2 running shoe is the complete racing and fast-paced training package. The shoe has been updated with a better fit, especially over the top of the foot. The new upper mesh is designed to improve airflow around the foot. This design saves energy by helping to keep the foot cool so the body doesn’t have to work as hard to regulate temperature. The midsole is constructed with FLYTEFOAM Propel technology to promote a high-energy return that increases the bounce effect with a responsive energy return. The DUOSOLE outsole construction offers lightweight flexibility and traction to help you go further. Featuring a molded AHARPLUS heel plug to reduce excessive wear, this shoe also implements a PROPULSION TRUSSTIC system for added stability and responsiveness as the foot moves from foot strike to toe-off. Whether you’re a competitive racer or simply like challenging yourself to beat your personal best, the TARTHEREDGE 2 model can assist your fast-paced training and racing to the next level.
