I was excited about this shoe after reading the shoe information and the reviews. I'm so glad I got them. It's true what some say on previous reviews, the shoe size runs small and you should buy a half size larger. I did and they're perfect. They are so soft and comfortable and very light weight. At first I was a little skeptical about the advertised benefits of wearing these shoes. After my first long walk with them I noticed my posture automatically changed. It was so subtle. I didn't have the shoulder strain from slouching forward and my calves and hamstrings got a real workout. I love these shoes!
