I was a bit skeptical at first.  I've tried lots of other shoes that cost LOTS more.  After running in traditional shoes, my feet would go numb after about 20 minutes of running-compressed nerve.  I don't have any issues with these.  It's like your feet were designed to run in these.  Sole is thick enough to provide good padding on rough/uneven surfaces.  One thing:  You have to wear toe socks and you'll have to learn how to put them on so your toes line up.  Once you get it thought, they're great.  I'll never go back to traditional running shoes.
