The material is very soft with a lovely feel. The packaging is well thought-out so nothing arrives snagged. The individual socks do not arrive with loose threads. The height is not to the knee, just high enough so when you sit down and cross your legs the socks will be seen and not your skin above. They are just thin enough so they will fit in your shoes and not fill your shoes so much they would make your feet too tight. The colors are all useful.
