I normally wear a size 7½, or occasionally an 8, but a size 7 in these sandals fits like a 7 ½ normally does. Even holds a charge. Very comfortable and not too tight on the head. They are holding up great, very easy to clean off and he can put his own shoes on which everybody loves! I like this design because I know from years of past experience that this design is excellent for all day, do anything, wear. Proved very useful on numerous occasions since I bought it. It is so nice to get out of the shower and wrap yourself in this towel. Need a replacement auxiliary cords for a pair of beats by Dre headphones havent used them yet but the price was right will find out on Christmas morning how well they work My only complaint is that I wish the charging box was smaller but seeing that the battery life is so long, I?m willing to sacrifice that part, which is why I?m still giving these a five star review. Update 2:For listening to music, they are okay not bad as I thought.
