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 comfortable mesh upper provides a breathable, secure fit, while our signature roomy toe box offers even more comfort where it counts. The ZipFoamā¢ midsole pairs with our OrthoLiteĀ® Performance Insole for a soft step-in feel with optimal response. As the miles stack up, high-abrasion rubber on the outsole delivers ideal traction.
