I just purchased these not too long ago. I would have actually purchased them before then, however they never had my size in stock when they went on sale before then. They come unlined and on a comfortable sole, they're a fabulous Summer shoe.
Typically there is a good reason why something of this nature is so popular. Besides boots or shoes that cost this much are hardly a dime a dozen. However if you have so many in DOAK already I can see why you would want a different color.
