I have tried many other suppliers of knee socks and they all seem to fall down to the ankles except for the Trim brand. They are well washed and have not lost the ability to stay on their feet and function as expected "knee socks".
Pros
These knee socks are made from high quality flat knit fabric that will hold up through frequent wear and washing. This makes them a practical and economical choice for parents who want durable garments for their children.
