New to Spring Summer 2021, the Altra River for men has been designed to remain responsive and light, yet not as minimal as the Escalante & Escalante Racer. It is a touch narrower than other Altra FootShape running shoes, which may appeal to those who felt Altra’s are somewhat too spacious. As with all Altra running shoes, the mens Rivera is Zero Drop from heel for forefoot to help improve your posture and form.
TRY A 1/2 SIZE LARGER THAN USUAL
