I am a podiatrist who works in a large hospital-clinic setting working on very high risk limb salvaging patients. I must run from clinic on the 2nd floor to the patients on the 5th floor constantly, and I use the stairs for exercise and because it is quicker. My feet are so comfortable in these shoes, that I am not aware of any of my foot deformities since I have psoriatic arthritis in my feet. This is my THIRD pair of these shoe over the last 3 years. Absolutely recommend these shoes. By the way I have no financial connection with this company at all. My patients regularly comment on how attractive they are as well.
