I bought these shoes looking for a shoe that was going to be comfortable for walking and that would also give my leg muscles a workout and help with lower back pain. I found these on sale on Amazon so decided to give them a try after reading up on them a bit. I bought them in a 1/2 size larger than I would normally wear, but I am pregnant in my 3rd trimester for figured a bigger size was wise. The shoes arrived and they fit perfectly, they are very comfortable. I've been wearing them whenever I go out and so far my back pain is less and my legs and feet are not getting as tired as they used to. The shoes don't just feel good but they are beautiful, I may just order another pair, I like them that much!
