I did a lot of product research before purchasing these sneakers to help train for my first 1/2 marathon, including going to two different running stores and being fitted for a shoe specific to my foot and running style. This was one of the shoes that was recommended to me and I solely went forward on this shoe since it was cheaper. They seem to do really well on treadmill runs, but I find hamstring pain when I run on pavement. The padding or &#34;foam&#34; in the shoe doesn't offer as much for cushion during runs. Lastly, let me first say that these shoes do NOT claim to be waterproof what so ever, but I just have to say this is the MOST water absorbing and retaining sneakers I have ever bought. I have been caught in the rain twice with these and they seem to act like a sponge when it comes to moisture.  I have to add that I think this is not a good running shoe for distance runners. I have put on approximately 200 miles I these and they are falling apart.
