Oliver Pritchett writes in the DT:
“I was fascinated to learn that the Queen has someone to wear-in her new shoes, to avoid that uncomfortable blistery phase. Does this person have a job title, like Lady-in-Broad-Fitting or Mistress of the Instep?
And how does one get selected for the post? Foot size is obviously important; my guess is that the successful applicant would have to take a half-size bigger than the Queen’s, which would help when the salesman says: “It will stretch with wear, Your Majesty.” There would be rigorous tests of foot hygiene, of course, and evidence would be needed to prove that the person chosen had a clean record as far as scuffing is concerned.
The wearing-in process would involve standing for an extended period, as if taking a salute, walking at a measured pace, as if inspecting a guard of honour, and a number of dummy walkabouts.
There is one small worry. Actors often say they get into a part by starting at the feet and shoes. Is there a risk that the wearer-in will get into the part of reigning monarch so successfully that she will start to get above herself?”
And look who wears in the PoW’s suedes!

That would disqualify me, then. I scuff my shoes and have block feet.
Ah, Christopher, that’s what distinguishes us mere subjects from our rulers.
I just can’t see one of the socially degreed Brits doing this, perhaps another vital position filled by a Polish immigrant!
I have a few well worn in size 10’s lying about, do you think Prince Phillip would be interested?
How very…..
It reminds me of a cartoon I saw recently, but sadly cannot now find. David Cameron says to George Osborne, ‘George, please run off and warm the lavatory seat for me. There’s a good chap’.
