These shoes for a Monster High doll are a variation of the Barbie shoes I made earlier. The pattern for these can be found on my web site.
The main difference is that I finished the outer sole structure first. The first picture shows the untreated cardboard structure.
Then I painted the soles, except for the bottom, which does not need paint as it will be covered with leather.
Then I made insoles from two layers of cardboard, attached the straps to them, glued the outer sole and insole pieces together to form a finished shoe, and glued the leather outer soles in place.
