I hesitated to buy them because I have wide feet (DD) and diabetic neuropathy which can be very painful. But to my complete surprise and delight, they just fit perfectly. They're tight, but not tight. These are the best non slip socks I have ever worn. I have fallen several times and these socks are a godsend, they make me feel safe and balanced. I'm going to buy another pack of these because I want a lot of them. Absolutely the best product on the market for people at risk of slipping and falling.
