I don't know what men wear, but I do know this: If you like them and feel comfortable in them, wear them. No matter what you wear, someone somewhere is going to give you a funny look. So what? Yours is the only opinion that matters. Wear what feels right to YOU.
They might I would not but knowing other people they would.
It all depends on how they look on you.I wear them and love the way they feel and help my leg muscles.You might even get some nice looks from chicks but not all of them. The most important thing to have is confidence and lifes to short to worry about peoples opinions.Wear them dude!!
I think if you are feeling self-conscious you will not have an effective workout. There's no reason to be flashy at the gym if you are going there for serious purposes.
