Fortunately, I don't have the stereotypical female shoe obsession. I have three pairs of shoes for work -- all black & all from Clarks -- of which I regularly wear only one pair, what you'd call penny loafer style in the US (not sure what it's called here?). I have two pair of dressier shoes (both black - lol!) - one pair I bought at Clarks the heel is so high, I have only worn them once. The other pair I bought at Schuh & they rub the back of my heel so much just in putting them on - I have never worn them. (I should have taken those back.)
The best pair of shoes I have ever bought here are
Italian hiking boots (Trezetas). I think that's my favorite pair of shoes! Followed by the hiking boots I bought in France, and my Asics trainers bought in the US. (Oh and I have a pair of sandals from the US, as well as a pair of flip-flops -- but those have not seen the light of day this summer!

...like clothing manufacturers shoe manufacturers sizes are not uniform...
But that's the thing, I find British sizing to be the least uniform of all. I don't have these troubles with US and European sizing.
