First off, these are WORK socks.  So several of the other reviews should be ignored by virtue of that fact.

As someone who works 12 hours a day, 5 days a week in a welding shop whether the ambient temperature is 115 degrees in the summer or 50 degrees in the winter (they didn't like to heat the shop, we were supposed to just work harder) I can tell you that these socks are as good as they are ever going to get.  They are the perfect dimensions; not too big, or long, or overly thick.  They fit well in my steel toes.  I didn't feel like the material was bunching up in the toes.  My feet never felt cold or hot and, best of all, my feet didn't sweat.  That means that when I'm done at the end of the day my feet aren't going to smell.

I bought between 10 and 15 pairs of these around 2 years ago and I haven't worn any out.  They still feel the same way they did when they were new.  For socks they may be expensive but I never thought that I would love socks, but I love these socks.  I love them so much I may even buy a few extra pairs and store them in case they're discontinued.  That should say something.
