Tipi Toe Women's 6 or 12 Pack Colorful Patterned Crew Socks

Can you put these socks in the dryer?

Where are these made?

Do these socks shed inside, leaving bits of fabric on feet, toes, and carpets??

Is 5-9 the shoe size for women? Trying to buy it for kid and her friends and they're all between 5 and 7.
