A dedicated running track is a good middle option between street running and a treadmill. Usually the surface is a little softer. If there's a public high school or community college in your area you can probably run on their track for free as long as it's not in use.

Tracks are great texture-wise, but they come with their own problems since you’re only turning left or right. Body movement will compensate for this and it can lead to injuries if you’re not careful. My PT told me he’s sees a lot of this at his practice.
