"The Altra Experience Flow St was a great shoe. I went from having almost numb toes at the end of my runs to no problems at all. The wide toe box and low heel-to-toe drop that Altra is known for are a perfect fit for my feet. Altra has done a great job making a more stabilized feel while running"
Altra was founded in 2009 by runners Golden Harper and Brian Beckstead, who set out to challenge the conventional running shoe by isolating heel-to-toe drop as a critical, overlooked design flaw.
The brand pioneered Zero Drop™ platforms and its signature FootShape™ toe box, giving runners' toes room to spread naturally instead of being squeezed into a tapered front, all built around Balanced Cushioning™ for a more natural foot position.
While Altra remains committed to its zero-drop roots, it has since expanded into select low-drop models, offering a gentler entry point for runners curious about a more natural stride.
