Nice somewhat thick socks - ankle boot socks Mainly cotton (90%) I think they were weatherproof vintage brand 2 pairs never worn but washed once - 2 pairs worn once (so washed twice) I really like these socks but after washing they shrunk and now fit a tad too snug for my liking. They did fit my size 9 wide foot I just like my socks a bit loose. 4 different colors: black, burgundy red, like an olive green and gray using marled yarn
