Tali's Feet

So I've constructed the feet already and it went a little differently than planned, but they still look and feel great!

Supplies

Cheap, cloth based flats (in the Vans Skater shoe style). I got these for $5 at Walmart or maybe Payless.
3 mm Craft foam
Cotton Balls
Scotch Tape and masking tape
Marker

Construction

1. I put on the shoes and stepped onto the craft foam about half-way and traced both feet. 
2. Then I drew the shape of Tali's foot around the shoe shape. This became the bottom of the foot.
3. Cut out the foot and retrace it with some "seam allowance". 
4. Cut out the top and separate the toes from the top of the foot. 
5. With masking tape, tape down along the edge of one long toe. 
6. Curl the foam into a toe shape, trimming where necessary and taping it down. 
7. Stuff the toe with cotton balls so it's not so hollow and bendy. 
8. Wrap the toe in masking tape. 
9. Do the same for the other long toe. 
10. The small side toe is a little easier to do once the main body of the foot is put on. 
11. Put on the shoe and hold it in place on the sole of the foot. Measure some craft foam like a sandal.
12. Tape it down along the small toe, then wrap around the shoe with your foot still in it!
13. Continue to wrap with masking tape to reinforce the body of the foot. 

Attempt #1...I later changed the top part of the foot to be one piece.

Now the shoe can slide in and out of the foot cover. 

Tips: Use scotch tape instead of masking tape for smoother outer coat. I use scotch tape in some parts. 

If your toes don't look even, use cotton ball pieces wrapped in tape to extend the toe. 

You'll notice that my toes and the edge of the shoe are curved. This allows me to stand on the balls of my feet to give the tip-toe effect without it looking too unnatural. 

Walking: 

I have tiny feet so the extra length takes some getting used to when flat footed. It is easier to walk on the balls of my feet. 

Next step will be to cover the foot and shoe in black lycra.
