back brace?

Does anyone in here where a back brace for a back problems? I have to get one and I was just wondering how long you guys have had it and why. :)

I don't have one, but one the best runners at my school does. She doesn't seem to care, and I don't know about a single person who does.

This girl has been running since back in elimentary, so I'm guessing hers is do to some thing atheltic.
