Shoes can be daunting, but the best advice I can give (if you have the shoe) is to put the shoe on a piece of paper and trace along the bottom to make a footprint pattern. Then find (or take) a photo of the profile of the shoe. Use a computer or a copying machine to blow these 2 images up to your proportions, making sure that your 2 images are the same length. Use these 2 images as your cutting guides for your shoe cake! Good luck!!
