WHY PACERS CARRIES THESE SHOES:

The Altra Rivera 4 serves as a good introduction to Altra for runners and athletes interested in their balanced, zero-drop cushioning and foot-shaped lasts. The Rivera 4 is a true workhorse mid-cushioned running shoe with Altra’s responsive EGO midsole foam that will feel familiar to runners familiar with other brands.

The Altra Rivera 4 is also built on Altra’s slimmest-fitting foot shape, which offers a taste of Altra’s distinctive roomy toe box without feeling sloppy to runners not accustomed to Altra’s fit.

The Altra Rivera 4 is a great running shoe for runners looking to add a zero-drop or low-drop shoe to their rotation. As a lightweight and firmer-platformed shoe, the Altra Rivera 4 is also great as a versatile shoe for the gym or HIIT classes.

WHAT’S NEW:

The Altra Rivera 4 essentially refines what worked in the Rivera 3, which hit the mark as a true mid-cushioned, responsive, and zero-drop road running shoe. Overall, you’re getting the Rivera 3 with a sleeker look and more accommodating fit.

Thanks to an updated sock-like engineered mesh upper, the shoe fits a little better through the forefoot and offers additional midfoot width where many runners noticed some pinch in in the Rivera 3.

Lastly, the Altra Rivera 4 features an updated heel collar that provides more structure for a more secure fit around the heel and ankle.
