Classically loafers do not feature laces; at most, they contain
a decorative item such as a tassel. The picture below display's
the classic design of a loafer: as you can see, it features neither
a laces nor a tongue; instead, the vamp - as highlighted - extends
further up the foot, so as to ensure the shoe does not slip off.
There are a few example's of manufacturer's making loafers with
laces - such as Armani - but, it's debatable whether these shoes
can be described as a loafer, but rather as a cross between a loafer
and another style of shoe. As the image above shows, the loafer
is a distinctive slip-on shoe, a unique design which is hard to
mistake for anything but.
