I have never used expensive hiking socks. I use plain old cotton-blend sports tube socks and have not had a blister in probably 20 years.
For me it's all about the shoes or boots on my feet. If those are proper, the socks just seem to fall in line.
The only thing I do wear that is different is heavy wool socks in the winter (with heavily lined winter boots), but like I say, with proper fitting, good quality boots, I don't really have a problem.
As others have said though, I pack lots of socks and change them often.
