This year's version of the popular PRO Endurance has been fine-tuned to provide even better speed characteristics and more ventilation. The result is a running shoe that provides high comfort and an efficient stride even during really long runs. The shoe has a Px Foam™ midsole that is optimised to provide an explosive push-off and soft landing. This updated version also features a new upper made of highly functional, breathable and elastic mesh that works seamlessly with the foot for more efficient running. The shoe also features a sleek, aerodynamic design that helps you pick up the pace and reach your goals faster. The Endurance 2 is the optimal choice for elite athletes and recreational runners looking for a premium, well-cushioned shoe for both mass training and hard interval sessions. Built for tarmac and light trail terrain.
