I don't think you read my answer carefully
I will repeat it here and bold the parts you apparently missed....
Twisting motions cause a unique stress to the system.
Yes, I have seen this, and often these individuals have more than a problem in the achilles, including problems in the lower spine.
A full assessment by a structural medicine expert should be done.
In the UK, that is called a non invasive orthopedist.
A podiatrist should be consulted as well.
The fact is that twisting motions overly affect a vulnerable structural pattern.
You need an expert trained in looking at the WHOLE structural pattern.
There are a number of choices: a PM&R doctor is but one.
There are others as well.
Let me know you have further questions.
