down-at-the-heels

The phrase "down at the heels" is a vivid English idiom originating from a literal observation of poverty. It directly references the state of a person's footwear, specifically shoes where the back (the heel) has become worn down from extensive use, often causing the wearer to walk on the back of the shoe. This literal sign of neglect and lack of resources to repair or replace footwear became a metonym for general shabbiness and financial struggle. Over time, it solidified into a fixed adjectival phrase, capturing a state of dilapidation not just in dress but potentially in one's overall circumstances.

This is a fixed idiomatic phrase. It is not productively formed from separable morphemes for the purpose of this analysis. Its meaning is derived from the literal image of a shoe whose heel is worn down from long use.
