And that is why many people don't see boots as buy it for life. But the difference is the repairs the boot will need to keep them functioning. A boot might require a heel in 7 years. You understand it would be very strange to have a boot where every single component has been replaced. That is just a new pair of boots made over a longer period of time. The only benefit to doing something like that is if you get way longer out of the product, or save money/the environment. In the case of boots I can wear them for 7 years, do a resole, and wear them for another 7. And depending on how much you use them you can have boots decades later you are still use. For example I have a pair of boots made in 1984 but not a computer that is even close to that old. There is no way to keep that kind of old tech running for that long in a useable way.
