Men's Experience Flow ST

Experience a smooth, efficient road run with gentle guidance built in. The Experience Flow ST is designed for runners and walkers who want light stability without feeling restricted. GuideRail™ technology provides subtle medial guidance only when needed, helping promote a naturally stable stride while staying out of the way when you’re moving well.

Underfoot, a low 4mm drop and rocker geometry encourage efficient transitions and an easy toe-off, making the Flow ST a strong choice for daily miles, training runs, and long walks alike. An updated engineered mesh upper improves breathability, while the redesigned heel collar adds step-in comfort and security. Finished with Altra’s Standard FootShape™ fit, the Experience Flow ST gives your toes room to move naturally while keeping the midfoot locked in for confidence on the road.

How This Shoe Compares

Compared to Brooks Adrenaline GTS

How it compares: The Adrenaline GTS is more traditional and structured, with a higher drop and a firmer, more controlling feel.

Key difference: Stability is always present and more noticeable, while the Experience Flow ST delivers lighter, on-demand guidance with a smoother, more modern ride.

Why choose Flow ST instead: Lower drop, lighter feel, and a less corrective experience for runners who want stability without stiffness.

Compared to Asics GT-2000

How it compares: The GT-2000 offers more structured stability and a slightly heavier, more planted feel.

Key difference: ASICS targets moderate overpronators and longer mileage with a firmer, more controlled platform, whereas the Flow ST prioritizes efficiency and light guidance.

Why choose Flow ST instead: Lighter, more flexible, and better suited for runners who only need stability as fatigue sets in rather than all the time.
