Rubber gets brittle if it isn’t kept supple through flexing. The rest of the shoe last longer if given time to ‘rest’ from over-stretching or dry from sweat.
So if you have multiple pairs of shoes, cycle through wearing them. All your pairs will last quite a bit longer: you’ll keep the rubber supple, and you’ll rest the sock/upper.

Might want to cycle through them, but treat the unworn pairs really gently for the first few wears. Msybe they’ll still be ok.
