Because even if vegan shoes are made of synthetic materials, leather is still arguably worse. Anyway, having more plant-based materials to work with hypothetically means anything made of those materials should be more biodegradable. But you have a point, biodegradability almost kind of by definition means the product in question is one that’s not designed to last. There’s probably a middle ground that can be found, like shoes that break down into soil-enriching materials after 50-100 years.
