Multi-purpose athletic shoe Run, train, lift, play . . . Prio does it all with lightweight performance, efficiency, and speed. Low-to-the-ground for balance and agility, the Prio has an anatomically wide toe box for power-producing movement. At just 8.6 ounces (M9) with a breathable mesh upper, you’ll barely know it’s there. Plus, the dual-direction chevron tread and huarache-inspired tensioning system provide stability and ground-gripping confidence.
