Customer Rating: Summary: shin guards for an infant 2008-09-29 Comment: I ordered a medium. According to the size chart, that would be perfect for me. I'm 5'4" 115 lbs. They were by no means close to big enough. They are stiff, so I couldn't even wear them if I tried. I sent a complaint e-mial and never received an answer. Order an XXXXXXXXXXXL or not at all. Or you could always give them to your infant and start them out with soccer early
