I love teva mush flip flops! These are my second pair. I have worn them to the beach, to walk my dog, doing errands around town and just hanging out at home. There is no break-in time. They are comfortable from the first moment you put them on. Last year I had a pair of madalyns that were not mush. They were comfortable as well, but the mushes are even more comfortable. After my first pair earlier this spring I had to have them in a different color. I will say that they run a bit small. I usually wear a 6 1/2, but the size 7s I have fit with no extra length.
