As long as I remember I've been a huge fan of beautiful shoes.
... It's also a question of comfort and practicality. Bad shoes are always bad shoes. They're bad for your feet and they look bad. That's it. So investing in a good pair of shoes is not only wise but a favor for your feet. They don't have to be the most expensive ones but usually the more expensive the better the shoe. Just go to Italy and see how much they appreciate hand made, made-to-measure shoes. There you go.
My favorite pair so far... Black, classic with a twist. So comfy you don't have to throw them away or change halfway the evening.
