great socks
I'm a size 8.5 and the medium fit great. I wanted a lightweight sock that I could wear with runners, loafers, etc., but that wouldn't be seen. (It's sometimes nice to have the feel of the sock but not see it!) These are terrific as they are comfy (as with all of my smartwool socks), stay on, but don't show. Colours are basic but go with everything. Very happy!

Outstanding!
I am a big fan of SmartWool socks. I had purchased this style a few years ago but only bought one set. Since then, I have been searching for them - not to be confused with the Women's Hide and SLEEK sock (that is another excellent sock but better for ballet-type shoes). I like to wear these socks with just about everything - the days I don't feel like going barefoot around my house or the days I don't want to go sockless with shoes or boots. They fit great covering more of the top of my foot and they stay on even with boots ... they do not slip off at the heel like most in this style. I trust the SmartWool blend for durability and comfort - my feet tend to sweat, so this is a nice brand to keep my feet warm and dry.

Great Socks!
These socks are great! I wear them with moccasin type shoes and boat shoes and they don't show. They also don't fall down and get under your feet when you're wearing shoes like a lot of socks this cut do. They're smartwool so they don't get smelly either which is great. A great sock for in late fall/ winter when you want to wear cuter shoes and still have warm feet. Nice to just wear around the house too.

perfect
I always thought wool socks would be itchy- not so. My feet stay dry and cool all day. Socks hold up well through washing and drying. Highly recommend.

Great no-show sock
Thick enough to cushion, but thin enough to fit under lightweight shoes, and far more comfortable than cotton in hot weather.
