They fit well on wide feet. I would buy another pair if my size was available. I bought a second speaker. Highly recommended as does exactly what you would expect and good value. Says they are washable so whats the deal? Super bummed The sound is the best i have ever experienced, like in a concert hall where i am the only audience. 100% ordering a second pair to have as a back up! My foot is pretty normal width and these fit just slightly more snug than my other flip flops. Beautiful shoes, unfortunately cannot wear them as I am a UK 5 and these are a U. The stores I shop at are no longer carrying slippers, or at least they now have very few, with none in my size.
