I don't know exactly what it is.

But there's just something about a flat from Urban Outfitters. They're not necessarily the most comfortable shoe (I mean, they get the job done, but they're no Naturalizers). They probably only last one season, two if you're lucky.

But just look them. The sleek shape that forms perfectly to your foot. The woven leather patterns, the V-neck toe, the sheer lace overlay. The fact that they often get marked down as low as $6.99 (see prices below).

They're a perfect finish to a pair of skinny jeans and T-shirt or to a summer dress for the Pitchfork Music Festival or Lollapalooza this summer. And although I wouldn't walk 10 miles in them, they give you hours of comfort and support and girly hipster fashion.

Here are a few of this summer's flats from Urban Outfitters -- I order a few every spring. And right now, get free shipping of purchases over $75 (through April 27).
