The Snoozie's are essentially a slipper shapped sock.  If you are looking for a supportive slipper, this product is not for you.  However, something to slip on that is light and to just take the chill off your toes, these are perfect.  I ordered a small and a medium to see which would fit better.  I wear a 6.5 shoe size, and the medium was just a bit too big, but for me the small was perfect.  I also like the variety of colors.
