Why Shoes Left Unworn for a Long Time Get Broken Easily When Finally Used?

I normally experience this with leather (or fake leather) shoes (men’s and women’s).

And is there any way to mitigate this problem without regularly using said shoes?

  • Do you mean the upper, the sole, or some other part?

    For the upper, leather needs to be taken care of. I’m not an expert on that as it’s never been worth it to me to deal with that. Fake leather has certain additives that eventually break down and then the material becomes less supple and resilient. That’s the same reason midsoles typically have a limited lifespan even without use as well.
