I ordered the 3 pack of pink/black stripes, solid black, and white and black...snowflake style I guess you could call it?  Anyway, the snowflake socks barely fit. I had to really stretch them to get them to fit over my calf. I do not have fat calves either. The other two pairs fit perfectly. They are all supposed to be size 9-11 and I wear size 9. Maybe the snowflake socks were a fluke... I AM happy with the other two though. They are very comfortable although they do feel a bit thin. I'll have to wait and see if they will hold up to regular use. If they do I would likely order more.
