On November 20, 1973, Cecil Slemp filed a patent for his invention — a footwear with heels and toe positions reversed — and he got the patent on July 16, 1976. The reversed soles of the shoes enable the wearer to leave inverted footprints.
Over the years, several designs of heels and soles aimed at helping the military to confuse their enemies appeared such as shoes that left footprints that resembled an animal’s footprint. However, shoes with inverted soles was a new thing at the time.
Slemp stated that this would help soldiers to fool their enemies by leaving false trails. This would be suitable in snowy, sandy, and muddy terrains. Standard military shoes and boots leave noticeable footprints on those terrains which the enemies could take advantage of. Using the “backward shoes”, the odds of the enemies tracking down the ground troops would be reduced.
This can be useful during secret missions, combat situations, and ground patrols. Even if the enemies find out the existence of the shoes, they would still be effective since the enemies would now have doubts about the authenticity of the footprints. The psychological implications of the mere existence of the “backward shoes” can be significant.
Now, a bloody footprint won’t lead a Sherlock Holmes wannabe to the evidence, it will lead him to the murder scene!
So, what do you think? Do you think that this is really useful?
