Abstract
A sole structure includes a foam element extending from a forefoot region to a heel region. A lower surface of the foam element includes a recess formed in the forefoot region. The sole structure also includes a posterior cushioning arrangement extending along a peripheral region of the sole structure from a heel region to a mid-foot region, and an anterior cushioning arrangement disposed in the recess of the foam element. The anterior cushioning arrangement has a proximal end adjacent to the lower surface of the foam element and a distal end formed on an opposite side of the anterior cushioning arrangement than the proximal end. The anterior cushioning arrangement includes at least one medial bladder proximate to a medial side of the sole structure and at least one lateral bladder proximate to a lateral side of the sole structure.
