Cheap and uncomfortable
"The shoe construction feels cheap- the soles are plastic and insubstantial, and the cut of the loafer means the back digs into your heel and the top rubs against your foot bone. These are expensive and they probably cost nothing to make, just feels like a rip-off. Wish I had spent the money on a nice pair of leather loafers instead."
