Stays in place!

I was worried about buying 2nds for performance socks because I didn't want them to bunch weirdly, but these didn't. They're perfect. They stay in place in my boots, and I even wore them running in a snowstorm, and my feet stayed warm and dry (of course, my sneakers were waterproof, so that helped). Also,even though they say "lightweight", they are still thick and warm.
