What is a trouser “break”?
The “break” in one’s trousers is the amount of fabric that rests over the instep of one’s shoes. Traditionally, trouser breaks may be a quarter, half or full inch although a full break can often create an impression of droopiness. The shoes you wear with a certain pair of trousers will sometimes determine the type of break required. For example, heavy-soled, chunky or bulbous toe shoes require a longer break than narrow, streamlined loafers.
