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.
