I have been wearing Teva Mush Sandals for many years now. I think I am on my 4th or 5th pair. I find them very comfortable. The sandals mold to your feet after a few weeks wearing them. They get more comfortable the longer you use them. I usually get 1-2 years of use out of a pair before the bottoms wear out. I usually wear them 4-5 days a week year round when I am not at work. These are my only choice for flip flops.
