Running, is this something I should be concerned about? Has it happened to any of you?

So I've recently started to get into running and I noticed I hit my right ankle quite often with my left heel, you can see the wear it has already caused to my shoe, is this a problem? I play football so I'm not exactly new to running and sprinting and I've done this on the field as well but I never thought much of it, but now that I'm getting some miles in I noticed I do it a lot. Anyway is this really that big of an issue? Has it happened to any of you? If it is an issue, how can I fix it? Thanks for reading :).

TL;DR I hit my ankle with my heel, am I going to trip and fall off a cliff? Look at this too.
