Altra Experience Flow ST - Guided Stability Meets Natural Movement

Experience a new reality in stability running. Featuring GuideRail™ technology for gentle medial guidance and the new lightweight Altra EGO™ P35 midsole foam, this shoe delivers an inherently stable yet euphoric ride. Engineered for daily miles and training runs where comfort meets natural movement.

Intelligent Stability

GuideRail™ technology provides medial guidance that kicks in when you need it, supporting natural foot motion without overcorrection. Unlike traditional stability shoes that force your foot into a prescribed path, the Experience Flow ST guides gently, allowing your stride to flow naturally whilst preventing excessive inward roll. Perfect for runners seeking subtle support without sacrificing the natural running experience.

Lightweight Responsiveness

The new Altra EGO™ P35 midsole foam delivers an efficient, responsive ride that doesn't weigh you down. This advanced foam formulation provides just-right cushioning for daily training whilst maintaining ground feel and energy return. Whether you're logging easy miles or tempo runs, the P35 foam keeps your legs fresh for the next session.

Natural Fit Philosophy

The signature Altra Fit gives your toes room to spread naturally whilst securing your midfoot for confident, stable movement. A low 4mm drop with rocker shape geometry promotes natural body alignment and an efficient toe-off, reducing strain on your Achilles and calves. The updated engineered mesh upper enhances breathability, and the redesigned heel collar provides improved comfort that eliminates hot spots during long runs.
