I bought two pair of these socks a few years ago, one gray heather and one dark khaki. They were so comfortable that I bought two backup pairs, in case they became unavailable later. The backups are still in the original packages, because the first two pairs refuse to wear out. They've been worn and washed countless times, and they still show almost no wear. These Wigwam socks don't pill, either. I use these hiking socks mostly as casual socks and for 2-4 mile outdoor walks; for hiking and serious outdoor activity that requires a hiking boot, I prefer a slightly thicker sock with a wicking liner. However, I've hiked in these socks, and they're fine. I wear the socks without shoes around the house, which is usually a death sentence for the sole, but not with these Ultimax socks. The socks wick well, and the inner loops provide a very comfortable cushion. These socks are a superior product and well worth the price.
