The pedal assembly:
The shoe attachment:
Attached to human foot (note high fashion style):
Attached to pedal without cyclist (not the intended mode of operation):

I did test tonight only briefly (it's raining, not optimal test conditions) but it was successful! I could pedal one-legged, pull up on the back side, and suffered no tombay falls at stoplights.
Think it will catch on?
