I recently got these Nike Free Run+ Shoes as a birthday present from Clayton. Let me tell you, they have changed my whole outlook on running. I feel as light as a feather when I run, no joke! I suffer from flat feet, so it's been a lifelong struggle to find any shoe that fits comfortably. The Nike Free design is based on the whole barefoot running theory (I'm a believer!), and they seem to mold perfectly to the shape of my foot. Awesome! I can't wait to run long distances in these bad boys.
