Ideally, you aren’t supposed to make a noise when you walk/run. If prehistoric man had made a noise moving, the prey would run away to leave man suffering in hunger.

If there were 2 machines doing the same task, one silent and the other unceasing “khr khr” unattached back-heel dragging on the ground and “flop flop” unattached back-heel hitting the bottom foot, wouldn’t you choose the silent machine?

Please have some social etiquette and not alert the ones whom you are walking/running around!
