I'm a straight middle-aged man who regularly wears pink shirts and sometimes pink pants. I honestly don't think anyone has ever given me any kind of look and I'm not the least bit self-conscious about pink clothing.
11 years ago, I was dropping my daughter off at kindergarten and a kid walked up and said, "Hey! boys can't wear pink!" I smiled and said, "Whoever told you that was wrong." That's the only time I've ever seen anything.
Is there something specific about sneakers?
