The loveliest socks for anyone who works outside are Corrymoor mohair. The Companion style is my personal favourite; I buy two pairs a year and with reasonable care (no boil wash), they go on for years but they do get a little thinner, which makes them fine all year round except very hot summers. No, they don't itch. They also never smell even if you wear them for a week. Trust me on this.
I second mohair ( goats’ wool) socks . I buy mine from a local breeder but she is very low on stock at the moment . Named by my Son in Law “ The Best Socks in The World ™️“ I have heard that Corrymoor are equally good .
