adidas Mens Ultraboost 22 Running Shoe

Foam upon foam creates a thick midsole built with adidas's special Boost technology: thermoplastic polyurethane (TPU) particles formed into cells around tiny air pockets. These pellets work with the plastic midsole shank to create noticeable rebound with every step rather than marshmallowy-soft cushioning. The slight rocker gently guides even the worst of heel strikers toward the forefoot, creating a perfect blend of easy, forward motion that feels great on tired legs. Great preowned condition in size 7
