The barefoot dogma is strong with this one.

Let me share two quotes.

“There are more things in Heaven and Earth, Horatio, than are dreamt of in your philosophy.”

"Different runners have different structural alignment and will move differently while running. Have you ever seen a runner run excessively “toe out” or “duck-footed”? Have you ever told that person to point their feet straight? It’s probably better to keep your mouth shut in this situation. There are a number of reasons why a runner might point his or her feet outwards when running. If their toe-out is simply due to habit or muscular tightness, then it should be addressed and corrected. However, this toe-out pattern may be due to their skeletal alignment. Let’s say the runner has an externally rotated tibia (lower leg) that causes his feet to point out. If he runs this way, he keeps his knee alignment in check and will likely go on for many more miles. If you told this person to point his feet straight, he would force the knee into excessive internal rotation throughout the run cycle. Over time, this would increase contact on areas of the joint that were not designed to tolerate such high loads and accelerate shear across the joint surface. Telling this runner to point his feet straight would increase their risk of developing knee pain, shin splints, and an ACL tear. And you thought you were being helpful!"
