Altra Rivera

Altra believe in three over riding principles that guide each shoe they make including the Rivera. The first is a Footshape Toe Box that allows the toes to spread, allowing your big toe to remain in position for maximum stability and power. Secondly Fit4Her technology has a completely different fit for men and women's shoes designed around the key physical characteristics of the foot. Thirdly they believe in balanced cushioning with a 0mm heel drop for optimal alignment and to cultivate better form. The Rivera uses an engineered mesh upper for a breathable feel, and Neutral Innerflex outsole that is targeted for maximum flexibility and minimum weight. The EGO midsole combines a springy and responsive feel with soft comfort, for a perfect blend of sensations.
