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 the 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." Features Real weight: 300 g (Us 9). Altra EGO Max midsole. FootPod outsole. Max cushion. Stack height: 30 mm. Breathable Engineered Mesh upper.
