For the girls with difficult sized feet:
If you (or even friends) go on holidays to Asia, see about getting some shoes made! I got shoes made in Vietnam (pretty cheaply, okay quality but you could pay more for really good quality and it's still about the cost of shoes at home or less) and they were great!
They measure the widest part of your foot, the longest part of your foot, and then trace around an outline on a bit of paper so they have your foot shape/size exactly..
You could buy a bunch of pairs!
And its a good excuse to go on holidays
Just make sure you have suitcase room!
