I wear hiking boots almost everyday. [My boots eliminate my plantar fascitis and I live at national parks. Literally. :)] Therefore, I need socks that wick sweat, don't bunch up and cause calluses, are high enough to go above the boot top and can stand up to the torture of laundromat washers and dryers. These socks fill the bill. They work as well or better than the expensive hiking socks at rei and they keep their shape and do not shrink down to toddler size. I love them. My PC should be this good...
