A minimalist recovery masterpiece, the OOmy Zen distills years of expertise into a simple, simply revolutionary active recovery shoe. No unnecessary bells or whistles. Just pure, peaceful relief with every step. Featuring a seamless circular knit upper with Zen bands that hug heel and instep, and the advanced OOmy footbed with our proprietary OOfoamâ„Ē technology that absorbs impact like no other.  Zen is balance: mobility, pliability, lightness, power, integrated into a shoe made to move the way your body moves.

It’s easy to make a complicated shoe. But simplicityâ€Ķthat’s hard. For the Zen, less is more. Less constriction, more freedom. Less weight, more mobility. Less pressure, more relief. Think of it as a shoe that lets your body take a deep, restorative breath. A harmonious blend of precise engineering and cushion that transcends comfort, the Zen is the foundation of your new mantra, your secret to active recovery. Say it with usâ€Ķ”fooooooammmmm”
