This listing is for a used black REGUARD Calf & Ankle Sleeve compression sock and a new white Long Support Sock, size L. The REGUARD socks have peeling logo prints, but the functionality is not degraded and they are still usable. My calf circumference is 25cm, and they feel quite tight, so I think they are about size M. The long compression socks provide moderate support. As a bonus, I will also include a new DUNLOP half-length sock (25cm-27cm).
