I wear a size 10 - 10.5 shoe, got the 11-13 size socks and these are still tighter than I am comfortable with. It takes me a minute to get used to the feel of the sock stretched over my toes. The material is also quite thin compared to the ankle socks I’m used to wearing. The positives: The socks don’t slip and the patterns look cool, but I will not be buying again.
