Halflings are a people without a home. They wander through the kingdoms of taller races, never staying to long in one location, always searching for a place to make their own.
In ancient China, women bind their feet for cosmetic reasons, resulting in them not able to walk without help and walking in a shuffling gait.
Possibly this can be modified such that people do it for less stupid reasons.
