I have always tended to buy the cheapest things that I can, whereas my Sis, being more fashion conscious, tends to go for the better but more expensive brands. I have to admit though, it is great to put on a high quality pair of shoes, and feel the comfort. I suspect that they might last longer, as well, especially if I have a good wardrobe full of them.
I checked out some Dansko womens shoes the other day, and was delighted. The prices seem good too, not super-cheap, but I don't think I can match the quality for the money I will be spending on them.
