Unfortunately I have found leather a good material for some uses. About 10 years ago (before I was vegetarian) I was given a leather belt and leather wallet which I use daily. So far the wear on them indicates they'll have another couple of decades of use.
Since the core reason for my vegetarianism (and aspirational veganism) is sustainability, durability, repairability etc. is key. For boots/shoes specifically, in the pre-plastic days I guess I would have bought leather boots which, when cared for properly, would have lasted for years, and been re-soled several times. At the end of their life they would have rotted away with no ill-effects.
In our saturated-with-plastic-days I'm wondering what the best alternative is to leather for footwear? Most shoes are made of plastic, non-repairable, and not designed to last for very long.
If there was a case for making leather from wild animals which died of natural causes (and without a toxic tanning/dying process) then maybe that would answer my question. But that's not practically achievable in today's world, so I can't buy those boots in reality.
So are there any vegan/vegetarian boots/shoes designed to last and be hard-wearing, which aren't made of plastic?
