The above photo shows the bottoms of my Brooks Defyance 2 running shoes (pair "A", which is nearing retirement, at 480+ miles. Click on the photo for a closer view). I've been noticing the uneven wear patterns between the left and right shoes (switched in the photo). There are several areas that aren't the same, but I've circled the spot with the most obvious wear pattern differences. I had no idea this was happening. Furthermore, I don't really know what this means, technically speaking. It looks like my right foot rolls straight forward, while my left either lifts up early, or pronates more to the outside. If it's the latter, it certainly doesn't show more wear to the outside of the left shoe than the right one does. I really need to get videotaped while running on a treadmill and watch a slow-motion video to see just what I'm doing. Fortunately, I haven't suffered serious injuries because of this. It could be a leg-length issue, a hip alignment issue...who knows? If anyone reading this has similar wear pattern discrepancies, please let me know - especially if you know what is causing it. Like I said, I'm not really alarmed. Just curious.

I think you are right that it pronates more to the outside. The left shoe has slightly more wear on the outer edge of the shoe than the right one does. It's interesting to see wear patterns though...mine are completely different on each shoe.
