I have spent 3 months replacing shoes and boots that now hurt. Amazon reviews kept me searching until I ended up with this brand. I now have the Mukluk, Byker and Crush boot. When I saw the sandals at Amazon's prices last week I read the reviews and most people said these were easier to wear than a standard thong. I decided to give them a try. The boots have been helpful but I needed an arch support so I was not sure I could wear these. Well it so happens that my broken big toe which now turns out is held perfectly straight by that sling design.  NO more crunching cartilage.  NO arch support needed. These may save me from a bunyan. I am starting to understand why people say they are addictive. There must be some narcotic in that wobbleboard because a lot of painful places on my feet do not hurt. This is the best yet for my feet. THANK YOU Amazon Reviewers and Amazon.
