wear patterns

I trudged along Norris Dam for my weekend long run today. It was a mix of jogging and walking. The freezing cold wind off the lake made for a less inviting experience. I was planning on upwards of 20 miles, but got back to the car after 11 miles pretty relieved. I only met one biker out on the trail, I guess everyone else knew better than to brave the cold.Below is an image of the wear patterns from the soles of my shoes. With most shoes it can be hard to get a clear reading on the pattern, but these soles have tiny little nubs that make it easy. I was interested to see if there were any anomalies or imbalance issues. Some observations:

– most of the wear indicates I’m landing on the balls of my feet towards the outside. These are minimal shoes, so it makes sense I’m landing with more of the forefoot. The slight over pronation falls in line with my history.

– there is still some wear on the heel. I think my foot is striking down here secondarily, not sure. So I hit the ball of the foot first, then the ankle pivots down onto the heel before pivoting back onto the toes for the push off. If this is the case, I’m wasting some energy. Another possibility is I’m landing more on the heels on down hills. This would make sense, I tend to lean back and just let the gravity do its work, landing with the heels acts as a breaking maneuver to prevent going too fast.

– overall I don’t see any red flags, looks pretty benign. I’m not so sure how effective this test is. It’s sort of like reading tea leaves. I’m at least happy that the pattern is very evenly distributed, and also very similar on both feet. I may come back to this in a few months when I’ve put more miles on these soles.

  1. Landing forefoot, then the heel coming down and coming back up is natural movement. The the calf muscles and achilles tendon act like a rubber band, stretching to absorb the shock, then springing back returning some energy to your stride.

    1. Good point, agreed its the bodies natural absorption mechanism. Could one argue that having too slack of a tendon would make your foot pivot down too much? There are strong rubber bands, and there are loose ones. Just wondering, thanks.
