I work for a neurologist that specializes in pain management and have had several patients tell me how amazing these shoes are. However I did not decide to buy the shoes until my best friend told me that she had bought two pairs and then I must absolutely run out to buy these shoes immediately because they were that comfortable! I decided that after having over 20 patients tell me that these shoes have improved their back pain significantly and had my best friend vouche for these shoes. I wear the shoes for the first time today and they were surprisingly comfortable. I have rheumatoid arthritis and suffer from chronic back pain. However today I was able to stand on my feet the entire day and I had much less back pain by the time work was over. I would highly recommend the shoes to anyone who is looking for a comfortable shoe and stands up all day long. I actually have ordered a second pair the shoes in a different color because they were that comfortable!
