How it Works:

The Altra Rivera 4 is engineered for a natural running experience. Its Balanced Cushioning™ platform keeps your heel and forefoot level, promoting better posture and a low-impact stride. The Altra EGO™ midsole responds to each step with energy return and comfort, while the mesh upper provides structure and airflow. The FootPod™ outsole flexes with your foot’s natural movements, giving traction and durability on road surfaces. Slip them on, and you get a ride that supports comfort, performance, and biomechanics.
