Exactly. May be have good documentation, engineering practices and don't oversell a new model claiming "works exactly like the earlier model"?

Lol, I actually want shoes that don't have a manual, tbh.

Ok, my comment was in the context of airplane control systems/sensors/UIs, but yeah, more generally, things should fail softly

actually I would like that for my running shoes, I live in fear that changing shoe model would re-trigger knee issues, and I almost would like to always buy the same shoes.

Same for my hiking shoes. When some shoes work well, I buy several pairs out of fear of a new model replacing it.

I do the same thing with tennis shoes. If I like a pair I'll go back and buy 4 more pairs before they change the shoe the next year.
