These are great! I have just started to practice swimming competitively, and after wearing these the first time I thought they were to tight but because of it being made of lycra it just took some time to loosen up. Once they became looser they were just great. Even though these are suppose to be for racing I have been using them for mostly training. I have not seen any wear or tear yet to them however I have not owned them that long yet, only time will tell.
