I received a pair of these socks as a Christmas gift and even though they are the largest size they have , 14-17 , they are too tight on my size 11 wide feet. They are too short and narrow so they crowd my toes when I wear them as slippers. The tops are also too narrow and unless your upper leg is 4 inches in diameter or less they are tight enough to cut off your circulation. I cannot possibly see how anyone could wear these in a pair of boots unless the boots were two sizes too big. I will say that they look nice and appear to be of good quality but the knit is too tight and they do not have enough stretch to be comfortable once you get them on your feet.
