In contrast, Manchester had nearly a quarter of its men wearing the smallest size, 6 or 7.
London also had many men with smaller feet, with a quarter wearing a size on the lower end of the scale.
Women in England were found to have the largest feet in the UK, with cities in England taking all top 10 spots.
A spokesperson for Shoezone said: “In order to find where in the UK has the biggest and smallest feet, we analysed data of over half a million shoe sales, across 68 British cities.
“No matter how old you are, everyone should ensure their feet are measured accurately so that they’re wearing the correct size to support their feet.”
