We were wondering when these wonderful shoes would grace the world of e-commerce--today, we discover, they have. The Yves Saint Laurent cage boot might have been the most eye-catching shoe on the Spring 09 catwalks (Kirkwood, we're talking to you). Perfectly suited for summer with a heel that you could actually walk in, we think if you happen to have a spare $1,400, you should go ahead and grab them. Talk about an investment piece.
