I bought a couple pair of wool blend socks to use in cool and cold weather. However, my wife got a pair of all synthetic warm socks to wear around the house, and I've been eyeing them. They were less expensive, warmer, and are machine washable. I've been babying mine, since they cost about $10 a pair, and washing them by hand in the sink, but that gets really old. I really don't wear them much. Part of that is it's usually not that cold here, but the other part is not wanting to mess with the hand washing. I think next time, I'll get a pair like my wife's. After mine wear out. In 50 years.
