Rivera 4
Rivera 4 is a zero-drop road daily trainer shaped around Altra's slimmer FootShape fit. Versus the previous model, the heel collar and tongue were redesigned, with a thicker tongue and engineered-mesh upper updating lockdown and breathability. A 28 mm Altra EGO midsole pairs InnerFlex grooves with a FootPod outsole, giving the shoe a flexible platform for daily running, jogging, and speedwork.
