I think the issue here is an engineering problem, not necessarily a lack of demand. The sole of the shoes would need to be impracticaly/uncomfortably thick to protect the electronics and keep said electronics from digging into the feet.
No way, LEDs can be tiny. Just look at how many they cram into displays like your phone or TV. The biggest thing is likely to be the battery but those can be made in all kinds of form factors.

Those tiny LEDs also need to be protected. I du no, the forces involved in am adult walking ate much greater than that of a child.
