shoehorn

Definitions

• A smooth tool that assists in putting the foot into a shoe, by sliding the heel in after the toe is in place. This reduces discomfort and damage to the back of the shoe. By slipping it into the back of the shoe behind the heel, the user prevents the heel from squashing down the back of the shoe and causing difficulty; instead the heel slides down the smooth shoehorn, which then comes out easily once the foot is in place.
• (derogatory) Anything by which a transaction is facilitated; a medium.
• (obsolete) Anything which draws on or allures; an inducement.
