I have gotten this style flip flop for several years. When I got these they looked different than my old very comfortable ones. I have worn both pairs and they are so uncomfortable and painful on my feet that I can't wear them. I have done some research and discovered that Teva has changed the design. I am on a limited income and am very upset I wasted my money on these flip flops. The old style ones were much more substantial and better quality than these. I have looked for the old style ones with no success. I am on my feet all day at work and never had any trouble with the old ones. Not sure what I will do now for shoes. This is my first complaint with an Amazon purchase ..but this is worth complaining about.
