Yes, lighted shoes. The Pleaser name is in there. The girl says they are rechargable. Wonder how it works. Connector? Metal plates and magnetic contacts? Remove batteries to charge? Put shoes in inductive couple docking station? www.youtube.com/watch?v=-ZYH4loedps&app=desktop
The ones I saw being worn were at Viet Coffee. Led flashing did depend on girl moving, suggesting the use of pressure transducers. Actually quite impossible not to look at her as she walks.
Could make shoes so that couple of screws removes all electronics in one module. But don't want to compromise strength of shoes.
