1 pair of shoes, mine were $4 at Goodwill
Take a section of foil and fold it to be the same width at the toe of the shoes. Make sure the foil peice is about 3-4 inches long, depending on how much of a curving toe you want. Use masking tape to secure the foil to the bottom of the shoe right under the toe. Make sure you have a section of the foil at least 2 inches long on the front, then use it to mold the curled toe of the shoe.
Once the bend of the shoe is made, cover it with maksing tape. Continue the above steps with the other shoe.
Once both shoes have curled toes, cover each one with newspaper and mod podge. This will help the shoe look uniform, otherwise the toe will look different than the rest of the shoe when painted.
After the newspaper has dried, spray paint the shoe any color you want. You can cover it with glitter, add a buckle or jewel. The spiders on mine were rings I found at the party store. Since there wasn't an easy way to attach them with glue, I ended up using a ribbon to hold them on. Not my favoite since you can see them, but they will look great on halloween.
