Do not buy this. Does NOT stay on your foot. I had to throw away. Very frustrating to wear. Kept falling down into my loafer. Bought much cheaper brand and those worked 100 times better. Very disappointed in this product. Save your money. Buy something else.Despite being somewhat large, I'm giving this a full five stars. I have used many other no-show socks, and this is the first one that is elasticized without including an elastic - so there is no hard cord cutting into the edges of my feet in order to stay on. At the end of the day it's just as comfortable as it was at the beginning, and I have never found another product that can compete with that. Stays on well with rubber grips on the heel, and fits snugly but cuts away and doesn't show in various loafers and lace-ups. Definitely going to stock up on these..These socks did not meet expectations. They do not stay on my feet when I wear my "Topsider" shoes (which they are specifically designed for), and instead come off the back of my heel, so I end up stepping on them. Even if, for some reason, that is a problem unique to me, a further issue is that I have had the socks for less than a month, and they have already developed holes.Fir an extra large sock they are greatFirst of all, I am female and purchased these men's socks for myself. They are definitely worth the expense, as has been my experience with Gold Toe. I had recently purchased 2 cute pairs of oxfords to wear with dresses and cropped pants, and I can't stand to wear shoes without socks. I wasn't finding this style for females, but as I wear a female size 10 in shoes, I assumed these would not be too large. They are perfect. They are incredibly comfortable, let my feet breathe, and are hidden from view.The only no show socks I'd buy from now on. I've tried several varieties because you wouldn't think something as simple as a sock would vary much. You would be wrong! Other socks I've tried all slip off and annoyingly get bunched up in my shoe. Still others that don't slip, are so restrictive that they cut painful lines into my ankles. These are the only ones that remain comfortably in place all day. Get them!The reviews were spot on. They stay on and don't slip off, and they are comfortableFits great !Good quality socks. Fits good. Can't see them in my sneakers.It's advertised as 95% cotton while it is 55%. ReturningThin and had a hole in them first time wornLove this socks, they really don't show and they even have some kind of support
