UPDATE 10/06/2020: They have REDUCED the quality of the socks. I bought these 3 times. The first two socks orders were the same. NOW as of October 2020 they have downgraded the socks to a much finer weave - extremely disappointed. NOT like before. -------------------------------------------------------- ------- ---------------------------------------- ----- -- ------------------These are the best quarter socks I've ever had. Please if anyone knows of better quality socks please let me know. My biggest concern is the socks will "roll" all over me and/or the sock will ride up and down on my heel causing blisters. You are perfect!
