Failing that let the local shoe repairer stretch them for you at a reasonable price. I hope they do a better job than my then boss did in 1962
I was in between 'horsey jobs' and worked in the local shoe shop. The first time I had a customer with their shoes pinching, he said"Not a problem Madam, I'll just put them on our electric shoe stretcher- (to me) come along Miss...... and I'll show you how it works"
We went into the back of the shop and he proceeded to 'stretch' alternately the toes and heels on a broomhandle!! After a short time we took the shoes back to the customer, who pronounced them fitting perfectly! This happened many times whilst I worked for him!
In those days you had to learn all the shoe types and style codes, I used to fall asleep at night reciting them. Being the junior I was only allowed to go 'Forward Miss.....' if the senior staff were serving. The hierachy was even worse when I did a few months at Bourne & Hollingsworth in Oxford Street.
