Some might argue that shoes should live in the closet, but when I (finally) get a pair of Louboutins those babies will be displayed proudly. And since most women buy shoes because they look pretty, it makes sense to be able to admire them the other 300+ days when they aren't being worn. These moldings are the perfect way to do just that.
Living Etc. posted this out of the box idea as one of their solutions to shoe storage. They correctly point out that it will work best in an alcove as the ends of the molding can be flush with the wall. However, with some creative beveling this could easily work on any wall. The real challenge is finding a paint color that coordinates with all the lovely heels in your closet.
