I bought these socks for my husband who is on his feet all day long. He would come home with sore and swollen feet. His calves would also be swollen, you could actually see the mark around his calves where the top of his boots hit. I told him I was getting these, and he balked saying it wouldn’t work. Well, guess what, he is now eating his words and grudgingly admits that these compression socks are wonderful. He’s a size 12 shoe and his calves measure 16” around and these socks fit him great. From the first day, the swelling was noticeably less and he said his feet feel better. These socks come at a great price for 2 pairs and has fast delivery. I would definitely recommend these over the inflated priced other brands in the store.
