My husband got tubes 2 years ago and LOVES them, he keeps getting the same pair so I decided to give them a try. They are very comfortable, I do like them a lot, I usually wear an 8 but these feel a little loose, I am keeping them because its not a problem and I have already gone for a fun runs in them without any problem. I used to have a pair of Addidas running shoes that fit the same way, I think they run a little big, I probably will try a half size smaller next time.
