Once the boots are finished, mix some Plaster of Paris or Quik-rete. Pour the concrete into the boots and slowly drop in the mannequin legs. Take special care that the legs are straight and level because once the concrete hardens, you will not be able to correct any mistakes.

Adding concrete to the boots will add weight to the prop and you won't have to worry about it being easily knocked over.

The clamps shown in the picture are there to give the boot a more rounded shape. The boots had a tendency to flex inward, making an unnatural shape.

Note: Be sure your boots are waterproof!! Otherwise, the concrete mixture could soak through the boot and ruin your wraps!! If they are not waterproof, insert a plastic bag into the boot before you pour the concrete.
