Chloe's Leather flat v-thong sling back sandals are $470 at Barneys New York. A classic shape that won't go out of style, but a hefty pricetag for such a slight shoe!
This leather sandal from Land's End Canvas looks a lot like the Chloes, but it'll only cost you $69.50. Not cheap, but a much less expensive alternative that you can wear for many summers to come.
