I am fond of wearing sneakers. I never realized they would give me thick callouses on certain areas on the bottom of my feet. They feel uncomfortable, not to mention gross. The more you trim them, the thicker they grow back.
Watching tv earlier today, I saw an archive clip on lasers and how it can be used to peel a potato if calibrated properly. This gave birth to an idea in my head that maybe there is a similar procedure for callouses. I imagined it would be something that could measure the average softness and thickness of the skin hence removing anything thicker or harder on the rest of the foot.
If such a thing does exist, please let me know. I would be forever grateful.
