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.
Honestly at this point fuschia’s continued existence feels less like “investing in a product that will yield dividends long-term” and more “middle manager desperately trying to justify their job”.
