There must be a sodding chart somewhere online that says what shoe size vs what your foot width actually measures in cm to say what width you need???
It's been so long since I've had them properly measured (usually just try on 7 zillion pairs and choose the ones that fit best) I have no idea
but have spotted a bargain pair on Facebook that are an E so I want to check before I buy.
Everything I can find on google either just has comprehensive instructions to get the size or tries to flog me a measuring gauge.
Any ideas??
