A break is the length of the pants to wear the cuffs meet the shoe. Most menswear die-hards currently prefer to minimize that distance as much as possible, resulting in a cleaner silhouette because there's almost no bunched up fabric stacking at the bottom. This can also be achieved by cuffing your pants, but most dudes will still try to call you out for rocking perceived high-waters. Joke's on them though—they're the ones dressed like fools.
