Product Overview . Stability has never been more comfortable than with Aura 2. Our Y-Frame Guidance System combats overpronation by cradling the foot and works with the max-cushioned platform to deliver a smooth and plush ride.

The ZipFoam™ midsole pairs with our OrthoLite® Performance Insole for a soft step-in feel with optimal response.
