Find and print reference photos in the size you need. Then cut out a piece of transfer paper the same size as the photo. Place the photo over the transfer paper, making sure the darker side of the transfer paper is against the shoe. Tape it down on the shoe where you want the image to be and then trace over the image with a pencil. Press on the inside of the shoe while you work to firm up the surface for a better transfer. Remove the photo and then paint the image. Spray the shoes with clear coat to protect the image and then lace them up.
