Snoozies are made of soft cozy fleece that is washable and have non-skid soles.  You will love these.  Buy several styles-these make great gifts. Please note: These run a little small-if you wear a 6-6.5 you may want to purchase a medium, if you wear 8-8.5 you may want to purchase a large. 9-9.5 you may want to purchase xlarge. **The system will not let you order more than what is in stock, if you try to do so you will receive a "999.99" error in your shopping cart and you must clear your order and start over.**
