Sizing: The Ultraboost Parley style is very form fitting. The best way to describe it is that the shoes feels like you are wearing socks. They run a half a size large, so we suggest you go down a half size when purchasing. ie., if you are a men 's 12 try a men's 11.5
These running shoes combine comfort and high-performance technology for a best-ever-run feeling. They have a stretchy knit upper that adapts to the changing shape of your foot as you run. Responsive midsole cushioning and a flexible outsole deliver a smooth and energized ride.
