I specifically came to mention the hydrolysis issue. Most plastics/rubbers will have similar issues, and will break down faster if not used/flexed. Overall I agree with the other person that said you don’t need good hiking boots. The traction you’d gain isn’t huge, and you can easily do better adding Yaktrax/MicroSpikes/a cheap knockoff to regular waterproof boots. Hiking boots would be overkill for little benefit.
Sounds great, but completely unrealistic. People have almost universally embraced social media because we’re social animals. How would it disappear, short of an outright global ban?
