Whether you are traveling to a new city or working hard to reach your running goal, the Altra Rivera 4 can keep up with your active lifestyle. The Rivera 4 has all of Altra’s signature characteristics—a wider toe box lets your toes splay and a zero heel-to-toe drop promotes natural, balanced running. It also features Altra’s slim FootShape™ Fit which gives it a sleeker appearance and tighter fit compared to other Altra shoes.
