Slimmer. Sleeker. Snugger. This new, open-road-ready shoe is Altra’s first trim-fitting FootShape shoe. The 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. Transform your road-running with the tried-and-true Altra EGO midsole, a light and breathable engineered mesh upper, and a Neutral Innerflex outsole for flexibility and performance. The Balanced Cushioning platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment and better form. The INNERFLEX grid-like grooves in the midsole are designed to provide flexibility and movement. Go with the flow for all your road-running needs with the all-new Rivera.
