[ Skin Conditions ] Open Question : what should i do to prevent foot blisters/scratches while skating?

I was recently transferred at my job so now one of my responsibilities is doing floor guard. I have to skate around the floor for hours on end and have been getting water blisters and bad scratches on my feet and ankles. So was wondering what there is I could wear so that those kinds of things don't happen. (It's wood floor skating, not ice) Oh, and don't say socks because I've worn 3 pairs and that stuff still happens.
