I have been completely satisfied with the three pairs of wool over the calf dress socks, purchased about six months ago. They are showing no signs of wear, and now that I have learned that they are best washed inside out in cold water and air dried, I anticipate that I will be surprised at how long they last. They are noticeably better made than socks I have been buying in the past. I more recently purchased the Pima cotton over the calf dress socks, and intend to continue purchasing from Boardroom Socks regularly. I am, personally a big fan of small private business, and the quality and value of your products illustrate why.
