They fit great, I would say they run a little large but that is how my feet like it. These were recommended on a blog I follow, and based on the reviews I read here, and given how sturdy they looked, I figured Id give them a try. They are the most comfortable walking sandal I own. Una gran experiencia. I could see this being a serious problem of i wore them all day. Audio sounds like youre listening to someone play music down the other end of a tunnel, its muddy and simply terrible. Installing my galaxy S8 (with or without the case), I felt like I was going to snap the silicone pieces. ====Edit: Anker support reached out after reading this review and sent me a replacement unit immediately, without even a need to ask. I only partially dry my work clothes to help save on wear and tear. They fit me like a glove - literally!
