I am a female at 5’3” and 130lb and my boyfriend is 5’9” at 180lb. We both wear size small. The tops of the socks are not ribbed like in the picture and like the product once was and makes them slightly more tight, but we still love them. Maybe go medium if you have a wide calf though.
My favorite thing about these socks is that they don't squeeze my feet. Plenty of room to wiggle my toes. Also slip on and off easily.
These are the absolute best socks I've ever owned!!! Do yourself a favor and buy a pair.
The best socks ever! They glide on to your feet like a second skin - a fur coat for your feet. Unlike most wool socks, they are light weight and fit comfortably in to your regular sized shoes. They keep your feet warm without making them sweat. I'll have to wait a while to see how they hold up with frequent washing, but so far I love these socks.
