If you have ANY doubts about what shoe to buy for walking and/or running, please don't hesitate to buy this shoe!  I was walking/running on the treadmill in a pair of New Balance and my feet and back were killing me.  I tried these shoes and I promise you my feet don't hurt and my back is 99% better.  I don't want to wear dress shoes to work anymore!  I put these on as soon as I get home in the afternoon and everywhere on the weekend.  I LOVE THESE SHOES!  I want another pair just in case something happens to mine or they discontinue them.  By the way... I was told at the shoe store where I bought them to buy a bigger size.  I normally wear a 7 1/2 and I bought an 8.  They told me and I've also read that as a runner you need at least 1/2 size bigger than what you normally wear.  I also bought superfeet insoles to go in mine to help with my plantar fasciitis.  I wouldn't be without the insoles.  Wonderful product as well.
