About Loafers:
Loafers or penny loafers are low, leather step-in shoes with tops that resemble moccasins, but have broad flat heels. Loafers have no shoelaces or buckles. Penny loafers are made of leather and are often worn for formal occasions.
About Nubuck:
This is a grain leather that has been slightly brushed on the surface to create a very fine velvet-like appearance. The texture of nubuck is finer than suede.
