Foot Calculator

What you need

This is what you need:

1. A well lit open area with hardwood/tile floors
2. 6 circle stickers (link to order)
3. A tripod (link to order)
4. Safety pin or paper clip
5. An arm chair
6. A tape measure
7. Tape or another safe way to mark a distance to walk
8. A helper willing to take photos and videos of you and is able to get up and down from the floor

You will do this a practice run now. Maybe you don't have all the supplies, that is totally fine. You can always have a second, third, forth run through. Just email the HNF coordinator at registrycoordinator@hnf-cure.org and ask to have the Foot Calculator assigned again. (please allow 24 hours for response).

You will complete a set of photo captures. Feet without socks or pants covering your skin. We are trying to see your arch so please be sure to stand on a hard floor, no carpeting. Please make sure the background is not busy or the same color as your feet.

You'll want to wear shorts, t-shirt and walking shoes (you'll also do barefoot). Please tie hair back if it touches your shoulders.

You will need 6 green stickers. One on either side above the ankle bone and one on the back of your calf a little higher than the side stickers. You will stand like a flamingo - with each foot to be photographed, showing the internal and external arches each alone. Then you will stand with your feet straight ahead and slightly apart for a photo of your heels.

Continue this at each spot: below the knee cap, mid-shin, either side of ankle bone, and inch down the foot to the big toe - acknowledging "yes" or "no" for the camera each time.
