Get the flat backermug. Slip on shoes for men (not loafers, moccasins, or lace-less converse), generally patterned, lace-less, and are canvas or cotton topped. Man flats are commonly worn by scenesters and emos, and are a common accessory to skinny-pants. Although called man flats, man flats are also commonly found on the feet of girls and should still be referred to as man flats.
