Needed new running shoes for work and home, and have been running with New Balance for years. I saw these on Amazon on sale and thought I would give them a try.  I bought two pairs.  I was a little surprised when I saw the soles, they're a little different, but in a cool way.  Have had them for about a month, running at work and home about 6 days a week.  So far, so good...the fit is very good, they are light and comfortable.  A couple of people have noticed the soles and asked about it.  Verdicts out on whether the design of the sole makes them a better running shoe or not, but time will tell.  I have had a bit of ankle pain in one foot and knee pain in the other leg off and on a bit, and I haven't had it with these shoes (of course, that could just be because they are new).  All in all, with the sale price and free shipping, I think they were a good buy.  I would recommend them.  I couldn't decide whether to rate them 4 or 5 stairs, so I went with 4 stars but not because I don't like the shoes.
