Concept for keeping someone walking while wearing high heels

I’ve come to understand that walking in heels doesn’t strictly count as bondage, but it’s a concept I wanted to use for keeping someone moving while they wear them.

The plan was to attach a button or switch to the heel of each high-heeled shoe. I’m fairly confident that when we walk normally, one heel is usually on the ground at any given time, alternating back and forth as one lifts while the other descends.

So, I should be able to wire these buttons into switches so that walking provides a reward, or stopping results in punishment.

The goal was to connect everything to a vibrator. When either heel touches the floor, the vibrator stays on; if both heels are down simultaneously (or neither), it turns off—essentially an electronic XOR gate, assuming my physics knowledge holds up.

There would need to be some clever mechanism to prevent just standing still on one foot, but this is a concept I’ve been mulling over for about a year. If someone has the technical know-how to build it, I’d love to see how it turns out:)
