Japanese wave inspired custom painted chucks. These are really simple all you need is a black sharpie and white watered down acrylic or fabric paint (and a small paint brush would possibly help). Find an image you like and one that matches the colour of the shoe, do not, under any circumstance use images from Twilight. You will have to paint the same image four times, so choose something relatively simple.
Draw the outline with the black marker, no point using a pencil, it won't show up.
I painted several layers, building up the white. Repeat on all sides until you see waves when you close your eyes and slowly go mad.
