Dr. Scholl's MediQtto Super Cool for Sleeping New, Unopened Probably full leg. It extends almost to the crotch. I measured it, so please use it as a reference. Size → Since there is no box, I estimate it to be size L, not M, based on my body type. Total length from toe to thigh: approximately 77 cm Thigh width: 12 cm Toe width: 8 cm These are the measurements of a used sock, not the new one. Since I don't know the exact size because there is no box, please understand this point before purchasing! A few years ago? Probably about 4 or 5 years ago. I bought a pack of 2 at Costco, and this is one of them. It was too long and difficult to put on and take off, so I only used one. Please purchase if you don't mind the details, as it is a home-stored item. Yu-Packet Post Mini
