Very disappointed. I wear a narrow shoe and was excited to find this style came in my size.  I wear flip-flops without a problem IF they are narrow enough, but my legs hurt after wearing these a while from scrunching my toes the whole time  trying to keep them on my feet! The foot beds fit fine but the uppers are really loose. I bought another style , same brand in a narrow and the foot beds are so narrow I feel like my feet are going to spill over the edge. (???) Wish there was a standard measurement  for narrow width, at least within a brand.
