I have knee and back trouble. After reading the online reviews and a price that can't be beat, I decided to try them. They really are very comfortable walking shoes. They're a little too casual for me to wear all the time, but if I could I would wear them to work. As it is, I use them to walk my dog and my knee/back hurts just a tiny bit less. I enjoy them and may consider buying more in the future. I just wish that they made a dressier shoe with the same type of cushioning technology.
