I'm seconding (if thats a word) this question,
Although its not the best thing and it makes it even that much harder to deadlift I use heavy socks pulled all the way up and jogging pants also. I was thinking of doubling up on my socks but they will not fit into my Chuck taylor;s and I'm throwing off my balance and leverage. even with jogging pants and heavy socks pulled all the way up, I still go home with blood stains on my shins and scabs on my legs. Like someone above said, if your doing them right there will be some scraping.
But when you weigh it out, getting the PR Deadlift vs. scabbed up shins.....its up to the individual as to which one is more important.
