Moccasins are shoes that do not use a lacing or fastening system and are slipped onto the foot instead. They are sometimes referred to as slip-ons for that reason as well. They usually have a low or no heel. For men, women, and children, they are a style that can be casual or dress shoes. Loafers are not usually overly fitted in the heel, making it easier to get on and off, possibly with the help of a shoe horn. Loafers don't need lacing or tying, which is a big advantage for people lacking flexibility or dexterity to tie their shoes, like seniors.
