100% correct. The only people who might need orthotics are those with SIGNIFICANT leg length discrepancies.
I would submit that those who feel they need orthotics might not be natural distance runners, but sprinters or should specialize in distances under 1500m. Not everyone needs to, or should, run over 3K in competition. You may be genetically predisposed to another event, or should explore another realm of T&F altogether!
I don't think most people race long distances because they're naturally suited for them. Do you? I think they race them because they like them.
I'm definitely not suited for distance. I'm much better at 800 meters than I am at the marathon, no matter how many miles I train. And the reason I don't train for 800 meters is not because there is a lack of competition. There are plenty of open/all-comers meets in my area
I just find it a lot more satisfying to do well in a long-distance race race than in two laps on an outdoor track.
Fortunately I've never needed orthotics, but if they meant the difference between my being able to compete at long distances and not, then I would definitely wear them. And in that case, yes I would "need" them.
