Flat feet vs hyperpronated feet: Do they cause iliotibial band issues?

There are a lot of "quotation" marks here, demonstrating my scorn at not only these terms, but how they are misused, misunderstood, and incorrectly attributed as the cause of injury.

Rarely have I read an article more shot full of holes than the one you may read here.

The answer to this question, is of course, no flat feet do not affect the ITB, but before we delve into this, let's have a chat about this paper and the author's obvious lack of understanding about "a flat foot".

He is no orphan here because there is a common misconception that a flat foot is a "hyperpronated' foot (the author's term, not mine). Just key the words "flat foot" and "hyperpronation" into Dr. Google and be prepared for the onslaught of shocking visuals and words!

Well, without even delving into what a 'hyperpronated' foot is (a nonsense term is what it really is), let's look at the term flat foot.

The author states: 

"In the case of a hyperpronated foot during gait, there is excess stress placed on the kinetic chain of the lower limbs due to the collapse of the medial arch."

I am trying to not to hyperventilate here, let alone hyperpronate, but, the medial arch does NOT "collapse" in a foot that pronates more than conventional wisdom says it should. Of course, the arch is less obvious than in a "normal" foot, because it is lower to the ground. For the most part, the majority motion is in the frontal plane, and so by nature, the arch will be closer to the ground.
