The FootShape™ you love with a slightly snugger fit. The Rivera is ready for all your road-running needs, from training blocks to that weekly long run and everything in between. The soft responsiveness of an Altra EGO™ midsole pairs with the light and breathable engineered mesh upper, and the Neutral InnerFlex™ is creased to help provide flexibility, so you can be one with the road.
Weight: 6.9 oz / 197 gOur signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.
BALANCED CUSHIONING™Our Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment, better form, and a low impact landing.
ALTRA EGO™Our original Altra EGO™ foam is designed to provide added energy return and a responsive, yet soft, comfortable feel.
INNERFLEX™These grid-like grooves in the midsole are designed to provide flexibility and movement.
FOOTPOD™ TECHNOLOGYThis outsole technology actually maps the bones and tendons of your foot to encourage natural movement underfoot.
