I was indoctrinated by my first boss, a store owner, to only buy and wear nice shoes. Flats and flip flops included (although I cheated on the latter this past week).
On that note, I typically only buy Lanvin flats- they have a built-in heel support, they are 100% leather and when you buy them a size too big, they feel like house slippers.
However, Gap has introduced a line of comfy little ballet flats for just $39!
