Collaboration is key. That's why Altra worked closely with Elite Athlete and two-time Olympian Kara Goucher on every detail of the Paradigm 6. The result features our luxurious and responsive Altra EGO™ MAX midsole foam, a slimmer aesthetic that will have you questioning whether it's really a support shoe, and support features that will remind you that it is. The new Paradigm 6 is"in a category of its own.â"
