Concept for an indoor walking routine

Here is my first post and the initial scenario I’m putting forward. Please be gentle with any errors on my part! Someday plan… I won’t go out to a place where it’s suitable; instead, I want to be compelled to take a long walk! Naturally, dressed up nicely in high heels. Dressing up isn’t hard, but walking indoors gets dull, so I need a way to log my planned kilometers without laziness taking over. Technology is here to help. I’ll definitely wear stiletto boots or pumps that are locked shut. The key point is I can’t remove them until the distance is covered. How do we ensure this? With locked pumps, it’s simple—the keys stay away. For boots, locking my corset and hands behind my back handles both scenarios. The “easy” part now: how to verify I actually cover the required distance? The solution is straightforward: two buttons placed at either end of the available space. Once you press them in the right order for the preset number of rounds… the key releases. I don’t have to walk non-stop, but I must traverse the entire distance. Heels are notorious for causing pain whether you’re moving or standing still… so it’s better to keep going! Imagine resting too long and then having to finish the remaining miles anyway… Disclaimer: * “Don’t try this at home unless you know exactly what you’re doing!”, “Ensure there are at least two other fail-safe ways out in case: 1. The main mechanism fails, or 2. You face an emergency!” * Alright, having said that, I’ll likely add a gag and a collar attached to an overhead steel line to keep me on the designated route. Back and forth until it’s done. Just wanted to share my plans. If anyone needs more details about the mechanisms, I’m happy to send them via PM, but even if you do, don’t attempt this unless you’re 200% sure! Comments are welcome of course
