Midwives did not understand germ theory, but still washed their hands and cleaned the delivery areas for delivery due to tradition.
Fun fact:
A Hungarian doctor tried to combine midwife tradition with his knowledge of modern medicine to get even better results. He required his nurses to clean on a regular basis, and required doctors to wash their hands with a chlorine solution before all medical procedures.
The result was a resounding success, with the complication rate as his facility being better than both the midwives and other doctors. However his methods violated social conventions at the time, so he was shunned from society and considered a disgrace. He died in an insane asylum.
Honestly if they got the cost down and figured out a better interaction mechanism than an app, I could see it being useful for older or disabled individuals.
For example, imagine someone is 55. They are still with it, and decently active for this age. However they have arthritis in their hands that makes tasks that require dexterity mildly uncomfortable. These kinds of shoes would be a pretty big boon for them in terms of staying active.
The issue is that they tried to make it some cool fashion accessory for Gen Z sneaker heads to buy.
