Trainers With Lights In The Heel
Red LEDs that flashed with every step, until they did not.
Light-up trainers were the most desirable footwear in any primary school, for roughly six months each.
The batteries were sealed in and could not be replaced, so the lights died and the trainers became ordinary trainers with a small lump in the heel.
Stamping deliberately in a dark corridor to make them flash was universal behaviour.
