I was wondering if you guys could tell me anything about these shin guards. I care most about the comfort or the guard itself and the straps. I used some old MacGregor shin guards last year and the straps irritated my legs. I know most people said don't spend a lot of money on shin guards, and I don't plan on it because I can get these for $30 used. I just wanted to know if any body has worn or is currently wearing these guards when working and how you feel about them. Thanks.
