But it's only ever been done once. That's right, there has only ever been one wearable working shoe-phone made. And it was made by a guy named Dr Paul Gardner-Stephen in Adelaide (in the world's sexiest country), who hasn't yet fully documented how he did it here. He also made a shoe bluetooth-headset, and thankfully he provided plenty of details. If you're ever looking to make a shoe-phone that's a little more technical than mine, he's the guy to talk to.
Anyway, due to the detail he provides, this instructable is largely based on Paul's shoe-headset, except... with a phone.
Things you'll need:
1. A nice-looking pair of shoes with wooden heels. The heels need to be big enough to fit a box 77x43x17 mm. If they cant, you'll have bits sticking out.
2. A Panasonic GD55. I.e. a SERIOUSLY tiny phone.
3. Big feet (to put in the big shoes)
This is where I got it all:
1. Shoes from a local op shop. I had to go to a few to find something that was good, but I found them eventually - $10
2. Phone from Ebay. And it came with a free headset - $46
3. Feet... well, I've had them for a while...
2. Kitchen knife and fork
3. Strong glue (Liquid Nails)
4. A tiny little Hex screwdriver
5. A drill
6. A jigsaw
To make sure your shoe has wooden heels, look at the side of the shoe. You should be able to see a small line between the base of the heel and the wooden bit.
Or, if you're lazy, you can just buy this one on eBay.
