This Memoi knee sock is really stylish. This sock runs a little narrow and definitely smaller in the foot than JRP. If a girl wears a size 30 shoe she will probably wear size 8 in this sock. It is 2 inches longer on the leg than a JRP knee sock but the foot part is about the same as a JRP sock, meaning a size 10 in this sock has the foot of a size 8-9 JRP and the leg length of a size 9-11 JRP sock. In case it's hard to see in the photo, the majority of the sock is a blueish white with pink accents. 70% Cotton, 27% Polyester, and 3% Spandex.
