Designed alongside Tomoa Narasaki, the UP-Duel has been developed specifically for the upcoming Olympics Speed Climbing category. This moccasin-style slipper has been built to be soft and supple, providing a sensitive feel while gliding up a competition wall at maximum speed. The premium RH rubber outsole ensures that every foot placement stays right where you want it to. This slip-on shoe also makes for an excellent gym-style trainer.
