I have heard some fabulous things about Teva Mush Flip Flops on these boards and am planning on buying a pair. They do not come in half sizes and I was wondering how they run (on the small or big side). I usually wear a 9.5 in shoes and do not have wide feet. Do you think I should order up a size or go down to a 9? I do not want to be tripping over them (they seem to be kind of chunky/bulky) but I also do not want them to be snug so I get blisters. Any help would be appreciated. Thanks!!!
