I LOVE THESE SOCKS!  I bought my first pair about 10 years ago when I discovered thorlos.  I only wear these slouch style socks around the house (since it's not the 80's anymore) and it's like getting a foot massage when I put them on.  They're incredibly soft and thick with yarn with a little added stretch.  They feel like they're cushioned.  They're great for winter (I live in the south even)!  I wear them with slippers to protect them from wearing out, and because wearing socks on hard surfaces can be slippery!

I wear thorlos (the shorter, thinner variety) for all of my athletic activities (I teach tennis, play tennis, and power walk) not just for their comfort but because they absorb sweat and wick it away from my foot.  And because the court can get searingly hot, the extra thickness is protective.  Definitely helps prevent blisters, too.  Can't imagine life without these.  I hope they never discontinue them.
