Cho-Pat Shin Splint Compression Brace?

misssuperstitious

I'm training for my first marathon, and while doing local races I've noticed a TON of people wearing these! Have seen them??? I wonder if they really work??? (FYI, I don't really have this problem, but I just think they're a neat idea and wondered if anyone had tried them)

I see a lot of people at races wearing compression socks...however, they could be these too. I've always wanted to try them. I don't have shin splints, but I hear great things about the socks in general.
