Blister Block is the poor woman's BodyGlide.
It's a J&J product that's sold in the drug stores next to the bandages (so it's a lot easier to find than BodyGlide, which I've never actually tried). It's a stick lubricant, mainly crisco but a few other ingredients that I'm not sure if they're functional or not (maybe I should just try plain crisco - wouldn't buy the stuff otherwise!
). Seriously, it doesn't turn liquid on skin contact the way I remember crisco doing, so I guess the other ingredients are some kind of stabilizers, or the oil is more hydrogenated, or something.
I resisted trying lubes for the longest time, always had this idea that they'd just soak into my socks and not work. I'd protect my feet with Spenco Adhesive Knit which was hard to find and not 100% effective. But the Blister Block is working great.
And, I can't say enough about wool socks. Not enough to prevent my blisters by themselves, but any more I don't wear anything else, year round. Just about 24/7! 
EDIT: I mean, I don't wear any other socks. Yes, I do wear something besides my wool socks.
