"Men's Altra® Experience Flow ST: The Experience Flow ST is a men's stability road running shoe from Altra built for daily miles and training runs - offering gentle guidance and a comfortable, efficient ride for runners who overpronate or want a little extra support without a heavy, structured feel.GuideRail™ technology works along the medial side to encourage natural foot placement, stepping in only when your stride needs it rather than forcing your foot into a fixed position. Underfoot, the Altra EGO™ P35 midsole foam keeps the ride lightweight and responsive, so the shoe doesn't feel like it's working against you on longer efforts. A rocker shape with a 4mm drop helps move you through each stride naturally and promotes an efficient toe-off without disrupting your gait. Altra's Standard FootShape™ fit gives your toes room to spread and move while keeping the midfoot secure - a combination that feels noticeably different from more tapered running shoes. The engineered mesh upper keeps airflow moving through the shoe, and the redesigned heel collar adds comfort right where you need it.Why Our Fit Experts Love This Shoe""I put these on a customer who was dealing with some overpronation but didn't want a bulky stability shoe. The GuideRail™ technology is subtle - you don't feel like you're being corrected, you just feel supported. The toe box is noticeably roomy, which makes a real difference on longer runs when your feet start to swell."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you overpronate and want a road running shoe that offers guidance without feeling rigid or heavy, the Experience Flow ST is worth a close look.
