I'm going to stop you right here. Patterns do prevent grass wear in this game.
It's most noticeable in winter. I have patterns everywhere in my town and I run everywhere (which is why I have patterns).
I had this long path of patterns in my town which I always ran on because it was just a straight path, but then I wanted to put a street lamp on it, but I had to move the path up a bit so the streetlamp wouldn't be too close to the cliff. When I lifted up the patterns, all that was there was dirt. I planted flowers and now the grass is revealing itself to be coming back.
