I’m not sure I was disagreeing with you in the previous statement. I haven’t thrown my shoes I’ve only put hundreds of miles on yet.
My point is that it isn’t exactly easy to find good shoes unless you invest a lot of money into them, especially in North America since we’re specifying locales. Most stores, even specialty stores, don’t carry custom-made or handmade shoes that are re-soleable. You could blame that on car-dependency, but it’s more likely due to an overall lack of understanding why one would need shoes that last much longer. People spend their money on cheaper, shorter-life shoes because they don’t have that much money to begin with.
