i have worn these types of socks for years and have them in many colors. they wash nice, stay soft and are cozy and warm. they work very well in boots. a little thick for sport shoes but do ok. great to wear in bed on winter nights. they do pill after 2-3 years and many many washings - but they don't get thin and wear out. even the elastic stays good. what other socks stay this good for this long?
