I saw this article and thought, "Hallelujah! I'm saved." And then I thought back to how and when my achilles pain started. I had had my shoes for a good 9 months. Not super broken in cause I did not run a lot last year but long enough that it probably wasn't the drop. I did buy new shoes thinking I needed new ones and went with a different company, so....I suppose it could be a cause of the continued problem.
I might try an insert in both shoes. I'll let you know how it goes.
