Why does the Queen...?

You can get knobbly feet from arthritis however careful you are with your choice of footwear.
At her age she is lucky not to be creaking more with arthritis. She clearly has the right genes.
Sensible shoes yes but she could wear colours in the same design.

Quite right to wear shoes she can be confident in. Not many women of her age will be walking and standing around as she still does. Comfy feet are crucial.

Oh I can't believe that!

It says that in my link, too!

Apparently HM has shoes properly made and has a member of staff same shoe fit to wear them in.

Gleaned from t'internet and stuck in my brain.

I can't imagine Her Maj having nobbly feet - she must have had hand made shoes all her life and, unlike some of us, has never shoved her feet into shoes that are fashionable but excruciating!

Maybe her feet are getting a bit old and knobbly and she doesn't want the bother of wearing new shoes that will be uncomfortable - even the elves and fairies can't always make new shoes that fit perfectly.

I've never really noticed before, but you're right!
