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 ZipFoam(TM) midsole pairs with our OrthoLiteA(R) 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. Specifications: Best For: Daily Running, walking Stack Height: 38mm(heel) x 33mm(forefoot) Weight: 8.7 Oz
