I recently came up with the pattern and I think it's quite like being barefoot!
Step 1: Measuring
Rip another piece of duct tape the same length an place it on top of the first one.
Then measure how wide your foot is from where your toes are and add an inch and a half.
Keep adding strips for how long your foot is and when you have enough strips to create the width.
Do the step again so you have it for both feet.
