My son has been playing ice, however this off season he wants to join a roller league. I have no experience with roller at all, so asking here, what will he need that is different from ice? Obviously skates, he currently is wearing Bauer Vapor X60s (4EE, so kind of wide), is there a reasonable analog for inline hockey? He has a crummy stick I imagine he can use. I imagine he will need a girdle and pants, would he need lighter weight shins? Anything else I'm missing, maybe gloves that he won't mind grinding up? Thanks!
