The cliche of womens need to own lots of shoes has some basis in practicality too. We need shoes that we can walk in, work in AND look good in. Which, as any woman can tell you, is often a contradiction. There's also the combining of trends and seasonality. We end up losing half our shoe wardrobe when we switch out boots and loafers for sandals and flip flops.
So when I find a pair of shoes that can serve a variety of functions, I feel as if I've just found an 80% off coupon at my favorite store. This shoe from Sperry combines the functionality of a flat with the summer/preppy style of an espadrille. It comes in a variety of colors shown here, and best of all is under $50!
