Adidas Energy Boost 2

Featuring a wholly new type of cushioning, the Energy Boost employs energy-returning Boost™ technology. To provide the most resilient midsole material ever manufactured, Adidas relies on a layer of 2,500 tiny thermoplastic polyurethane pebbles in just one shoe. Add to that a lightweight construction and you have a neutral shoe that will literally add spring to your step.; $160
