These slippers are very warm and made well.  The fur at the top is only at the top - it does not line the entire slipper.  However, the material that does line the slippers is very soft and warm.  Other reviews stated the slippers run small in size so I ordered one full size larger than what I usually wear.  They fit perfectly.  The sole is thin enough to feel like a slipper but sturdy enough to handle a quick trip to our mailbox in damp weather.  Really nice product.
