Calling aztimm & magiciansampras...
Also at some point you might want to have a foot doc (a sports one) check out your gait to see if any issues/alignment.
I had a tear in my Achilles years ago that took forever to recover from. I don't know that it impacted my gait as such, but I know I was much more careful on stretching/warming up post-that.
Cheers.
