I worked in retail for a number of years and had heel pain, sore feet and lower back pain daily. I started wearing crocs and my feet felt better. I'm almost 55.
I give these only four stars because the top straps are tight on me. My feet are wide and fat because I struggle to get these on. These are much better looking than crocs, a better price and my back hurts less when I wear them. I'm looking for my second pair, a nice operator told me that Marina, Maui and Wave are wider.
If the top strap ever breaks, I will put these inside my snow boots to use as a comfortable insole.
