The really great thing is all three straps are adjustable - toe, instep, and heel. I gave two stars only because of the design. It would probably be perfect for anyone Who has a typical instep and medium width. " I agree with other reviews that these sandals last a long time, mine usually last a year, but in Arizona, Im afforded more time to wear them without getting cold, and although the old ones look bad, theyre still comfortable. Not a bad product if you are, as I say, ok with Crocs type sandals, all foam, but I was looking for something different. Even then it takes minutes to acquire the signal. Im lucky that I wear a size 8 womens shoe and so I could get the equivalent of a mans size 6 - the smallest that they make. The case is really great, but not right for the JBL E50BT as they said. It was very difficult for me to put the money forth for these, but I needed good arch support as I have plantar fasciitis. It fills the room with such nice bass, you do not need to be sitting near it like most bluetooth speakers where the bass fades as you take a few steps away from it.
