I recently started to run races and bought these shoes for that purpose.  Running outside used to cause all kinds of problems - shin splints, runner's knee, etc. - but I don't have issues with these shoes.  I did buy Dr. Scholl's athletic insoles for them, so that should be noted.  The one thing that I like about them is also the reason I can't give them 5 stars.  The toe area is nice and wide so non-restrictive, but this coupled with my narrow foot leads to some bunching around the tongue that if I'm not careful will bruise the top of my foot.
