I have about five pairs of shoes that look pretty much just like that. I have one pair that's about ten years old and they are so worn out on the heels that there's no tread left at all on them.
I still like my Dr. Scholl's. Comfy, minimal tread, and they've held up to all the form work now for quite a bit longer than any other tennis shoe I've tried.
It's getting close to time to by a new pair, though. The sides are starting to weaken on me.
