Every summer I make my way through countless pairs of flat sandals. What with the heat, and the amount of walking I do in the city, heels tend to fall by the wayside, especially during the work week, and even the more expensive sandals are pretty much wrecked by the time the season is over. This year, I have decided to buy several, less expensive pairs that go with everything so that I can change things up on a daily basis. These are some of my favorites from around the web (how awesome are those stripy soles?). In fact, Urban Outfitters has a whole bunch of awesome choice (I really love these, and these!). What are your go-to shoes for summer?
