Here's a good way to make people uncomfortable when you run into them in public: wear a pair of these supremely-creepy barefoot shoes. Looking much too realistic for my level of comfort, they'll give you all the protection that normal shoes do with all the toenails that going barefoot provides.
And yeah, sure, there's probably a 70% chance that this is just a gross photoshop, but I'm pretty sure the technology and motivation exists for these things to be a reality, so I'm gonna let it slide. The weirdest part about these (apart from the obvious) is how awkwardly large your "feet" would look inside a pair of feet shoes. Oh man.
