I’ve been buying my alpaca socks from a men’s shop for $20 to $23 a pair under the brand name “Punto”. They aren’t super durable but I have so many they last two to three years. They are bad to pill and will lint up your dryer screen in a heartbeat. However, they are comfortable summer and winter and make great presents for my buddies. They are always glad to see me coming at Xmas. They are a hair sock rather than a wool sock and last longer if you wash them in baby shampoo.
