These would be much cooler if they weren’t made by Nike but they’re still pretty damn cool. And weird. Actually, they are in the concept stage, so they are not yet made by Nike, or indeed anyone else.
They’re basically different types of plastic you can stick on your feet to protect them from harm while still supposedly feeling like you’re barefoot. They have different ones for yoga, dance and cardio / combat training.
They could be a handy alternative for those suede-bottomed things I’ve seen dancers wear for types of dance that call for bare feet. I’m just not sure how they would stick on and whether they’d stay and whether it would be comfortable. Those suede-bottomed things just slip on, rather than stick.
