*** edited to add: sorry, I looked at the title and not the whole question. Below is my response for conditions above -5C. For cold conditions, I'm using Smartwool or a polypro/polyester blend, each of them thick and cushy.
Without getting into the question of whether the "Ray Way" is a religion and/or one that holds water, I did pick up several tips from reading Ray Jardine's book. One of which was:
Buy a 3-pack of cheap, nylon socks at Walmart, etc and use them on the trail.
I gave it a try. They give me enough rub-protection from the inside of my shoes, wash&dry really quick, weigh very little and last a long time.
Like many UL techniques, I also use it on business and vacation trips because I like to travel light. I have 6 pairs in tan for my hiking and to match many tan khakis. Now, I've picked up some black pairs to match my black loafers and charcoal-colored wool slacks.
Back when I was using cushy socks, SmartWool worked well for me. Wool needs to be washed far less often than cotton or synthetics.
