I have a lot of shoes.  I have a lot of sneakers, but none of them feel the way these shoes do on my feet.  I have a coworker who runs marathons, and he recommended these shoes to me.  He said he had tried many different running shoes out there, and nothing compared to these shoes.  He is absolutely correct. They fit like no other shoe I have ever owned.  They form around my heel, and have excellent support.  Like other reviewers, I have plantar fasciitis, and my feet felt better as soon as I put on these shoes.  They are lightweight and attractive.  I bought the 7(medium), and I usually wear size 7 shoes.  They fit perfectly.  I am already looking into purchasing another pair in a different color.  Totally worth the price.
