I love the comfort of these sandals but after wearing them for the entire summer, the straps have stretched out so much that foot doesnt even stay on the footbed. They are way too huge now and I can't even wear them. I'm considering buying another pair a whole size down if I can find them on sale. I wore these on a hike once which was a big mistake. I got so many rocks under my feet and there was absolutely no support since my feet kept sliding all around. It was better to walk barefoot.  However I still have hope that if I order a smaller size they might work out great. I usually have really good luck with merrell products.
