I found a two pairs of shoes that look exactly like these but all black at the thrift store. I bought one pair and took it home and sprayed them blue and added a yellow pompom. Remember? Now I desperately wish I bought the second pair because I'd LOVE to do this with the ribbon as lacings. I've gone back almost every week and haven't found another pair like them. What a miss.
It also looks like you could add black and white twine to the rims. ACK! I'm so mad.
