So kitschy-cool are these FACEBOOK SLIPPERS! Slip-on padded sole; the upper seems to be made of a foam type of material with a fuzzy black inner lining - the same fuzzy black material you see on the sole and the trim of the slipper. 
Size - exact shoe size unknown, but the entire sole bottom from tip to bottom measures 12 1/2" in length. The widest part of the slipper measures roughly 4 1/2" across.
