In the '80s when they were very 'in', it was best to get them from a proper shoe manufacturer like Bally (can't believe the prices on their website now
) because they were more foot shaped in a subtle way around the soles, heels and instep. They have to fit really well. Also, you need to be very 'ladylike' in them 
Unfortunately, a lot of shoe manufacturers have located to the far east, dumped their lasts and traditional techniques, and most shoes are manufactured in a way that is cheap and easy to mass produce, so that they fit the largest number of people - the population they are serving is bigger and more global, but they are more one-size-fits-all.
Cheaper ones have stiffer, flatter soles, don't fit well and are often too shallow round the toes to stay on.
I wear lace-ups now - court shoes were never good for my bunion
and I tend to wear boots or sandals with skirts, when I wear them. Shoes that fit firmly round the instep and do not put any pressure on my toe joints are much better and if they stay on properly, life is so much better
