I have given you the opinion of a "Shoe Professional" what more do you want?
My father also worked for Barretts ~ whenever anyone came in complaining that their new shoes pinched/hurt their feet he would say "leave them with me overnight, I'll 'ease' them for you". His method was to insert the handle of a broom into the toe of the shoe and pull on the back of the shoe with all his might, he would then sprinkle talc into the shoe. Each shoe would get this treatment. The next day he would fuss over the customer when they came to collect their footwear. "I'm sure that'll be more comfortable" he would oil as he slid the shoes onto their feet and they ALWAYS agreed. Whether it was his salesmanship, the broom handle or the talc I never knew. The Old Man always claimed it was "All in their minds me boy
". I suspect the overnight rest of their aching feet helped.
Get someone else to wear them in for you
I thought of that but then remembered the size of his feet
We are not talking twinkle toes here.
