JeasonaSlipper Socks with Grippers for Women Non-slip Gifts for Wife Daughter Granddaughter Girlfriend on Christmas

Do these fit a size 9

How are they lamb fleece if they are 95% polyester. I have ordered them but just spotted this. It's not lamb fleece ?

Do you just get one pair of socks for £10.99?

Why is there no size guide / size options available? Do people just get random sizes sent? Some here say 4-7, others 2.5-5. Weird.
