I love these socks! I have purchased other compression socks before, only to have them cut off the circulation right below my knee...could not wear them more than 3 hours without being uncomfortable. However, these socks by NurseMates are fabulous! I work 16 hour shifts twice a week and my legs feel great at the end of my shift! The construction of these socks provides superb comfort, they are soft and the wide band at the top is never too snug. I have told several people that I work with about the wonders of these socks. Definitely a must have.
