Definition of "shoehorn"

shoehorn

/ˈʃuːˌhɔː(ɹ)n/

noun
plural shoehorns
1. 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.
2. (derogatory) Anything by which a transaction is facilitated; a medium.
  Quotations
  I was about sixty feet ahead of this film in many spots, which speaks rather poorly for it. And I resented the heartthrobs which were planted in my bosom with a shoehorn via the "little child" process.
  1935, Don Herold, Going to the Movies, Life Magazine January 1935.
3. (obsolete) Anything which draws on or allures; an inducement.
  Quotations
  Now you cannot but observe, that most of our fine young Ladies readily fall in with the Direction of the Graver sort, to retain in their Service, by some small Encouragement, as great a Number as they can of supernumerary and insignificant Fellows, which they use like Whiflers, and commonly call Shoeing-Horns. These are never designed to know the length of the Foot, but only when a good Offer comes to whet and spur him up to the Point. Nay 'tis the Opinion of that grave Lady, Madam Matchwell, that it's absolutely convenient for every prudent Family to have several of these Implements about the House, to clap on as occasion serves, and that every Spark ought to produce a Certificate of his being a Shoeing-Horn, before he be admitted as a Shoe. A certain Lady, whom I could name, if it was necessary, has at present more Shoeing-Horns of all Sizes, Countries, and Colours, in her Service, than ever she had new Shoes in her Life.
  1652, Richard Burton, The Anatomy of Melancholy
