Great socks are one of those things you learn to value with experience.  Basically nothing I wear makes as big a difference in my comfort than having quality socks on my feet.  I walk a lot each day, up and down stairs, and it gets hot, and the last time I had a blister (more than ten years ago) I threw away every pair of cheap cotton socks.  Cheap socks get wet and slide around, while nice socks stay with your feet because they form to your feet, and nicer socks also provide a lot of cushion.  I've been swearing by "Thorlo" socks for 20 years.

You might think wool socks are too hot, but that's not how it works.  They are warm, but because they aren't rubbing against your feet, the friction of a cheap sock isn't there.  The blend of nylon and wool works very nicely with these socks for feeling comfortable for the 14 hours or so I've worn them at a time.  They are thick and heavy duty, and they definitely provide added cushion, which I found very comfortable.

Wool socks break in and shrink a bit to your feet.  In a dryer they can get distorted and shrink badly.  100% wool socks really shouldn't be dried at all, and I'm not drying these mostly wool ones (I hang them to dry).  After two washes, they were well broken in.  I'm not seeing any durability issues at all, but I've only had these a few weeks so far.

The color isn't really my cup of tea, but they look like the product photo exactly so you'll get what you're ordering.  I'm more impressed with the excellent quality of these socks.
