How can I preserve the inside-heel part of my shoes?

I usually wear sneakers/skate shoes. Naturally, there is wear-and-tear that comes over time with plain use: this is unavoidable and I know this.

But a common, frequent problem area is the “inside-heel” part of the shoe (I don’t know the technical term, if there is one). It always tears and is exposed long usually before the rest of the shoe is even close to wearing out to such severity. How can I reduce this?

I already use a shoe-horn, which is one of the best “simple” inventions I have ever discovered for myself. I am asking: is there some sort of tactic you use when taking off your shoes or something else that minimizes stress on the inside back heel? Maybe some of you guys not only untie your laces when taking off your shoes but also loosen them up entirely? Let me know! Thank you all.
