Received from my mother. I have tried them on. I usually wear a size M, but the size is too small for my 25cm feet. The size feels like S to M. The fit feels firm compression. Please refrain from purchasing if you are concerned as it is not a recent item. The embroidery inside is green. The box is my own and is not included as a reference. Compression socks that support blood circulation, comfortable fit. - Color: Black - Size: M - Features: Compression socks - Brand: Rhythm Thank you for viewing.
