Just remember the "ST" is for "stable"—easy! Formerly known as the Experience Form, the Altra Experience Flow ST is their go-to stability running shoe. Like its Experience Flow 3 sibling, the ST offers a gentle 4 mm drop from heel to toe. This gentle drop helps the Flow ST feel welcoming for every runner, while improving efficiency and relaxing your calves.

With this update, Altra redesigned the heel collar for extra comfort and enhanced the softer mesh's breathability. A refined tongue offers better in-motion flexibility, so all your group meetups, routine weekly miles, and daily errands feel more easygoing and enjoyable.

Matching the Flow 3, the same enjoyable EGO P35 foam takes care of your feet and joints. It's tuned to be just slightly plusher than before, easing your landings as the miles add up while keeping its lightweight balance of subtle bounce. However, the ST features a broader footprint than the Flow 3, especially through the midfoot, for improved stability and controlled pronation. This broader bast, combined with a medial GuideRail and structural overlays, mean your steps will feel well-supported through the last mile.

With generous rubber coverage on the outsole, the Altra Experience Flow ST stability running shoe gives you durability to last for all your daily training. Step in, find the confident guidance you want, and settle into your flow for mile after mile.
