Let’s make boots either from a substance whose surface friction property changes based on an electrical charge, or from two substances, one has very low friction and the other very high friction.
The high friction one can be disabled remotely to allow the low friction surface to come in to contact with the ground.
Why?
Because kids wear boots with little wheels in them that act like roller skates.
So how about a pair of “ice skates” on their feet instead.
These ice skates would work on almost any flat surface.
It would be like sliding around in your socks on a highly polished floor.
You could also create a set of gloves out of this.
It could well turn in to the new extreme sport.
