I have an old pair of Dansko's that I've had for four years. I'm a nurse and I work 16 hour shifts. With my old ones, I worked 80 hour weeks for six months straight in them. I was going through other shoes every other month. I have narrow feet and was used to tying my sneakers tight for support. A co-worker talked me into buying these, and I've never gone back. I was worried I would walk out of them, and that they'd fall off, or that while running to an emergency they would fall off. They never fell off once. It does take a while (about three days for me) to get used to walking in them. They are a rocker shoe, so they work almost like flip-flops; the heel of the shoe is supposed to stay on the floor as you start to lift your heel to take a step. I went to the store and had my feet mapped out when I bought my first pair, I saw that I stand with my weight on my heels. Well, towards the end of an 80 hour work week, my heels would burn like crazy. It didn't seem to matter if I was standing or laying down with my bare feet up. It got so bad that I had to take time off work. It seemed to help for a while, then the burning came back. After working only 40 hours in these, I had no pain at all...anywhere. My hips stopped aching, no knee pain, no back aches, and my heels felt like they used to feel. Normal. I was so excited to get this new pair and wear something besides black! I've submitted a picture, hope it shows up. In the pic, I put this new, red Dansko next to my old black one. You can see how well the old pair has held their shape! Next month I'm going to order another pair in blue, don't know why I waited so long to get another pair! These are also great to wear if you're working around the house or have a lot of errands to run and will be on your feet. I've read other reviews and I DON'T CARE if the finish will start to crack or peel away, it's what's on the inside that I bought them for. They were just delivered about an hour ago, so we'll see.
