Isn't that just posture?

>>51184894
No, posture that fucky (in toeing/pigeon toeing) is caused by poor structural alignments in the hips and legs. It's typically corrected when spotted in children before they grow into it permanently like the other two posters have admitted to. No clue if it's somethin you can fix as an adult without surgery.

I think they are trying to do a "baseball pitching stance". It would be impossible to dance if they really had one foot at 90 degrees to the other.

That said idols do adopt a bit of the old bambi legs, as with everything its supposed to be kawaii.

seiza sitting since childhood fucks up their knees

Dunno about this, but it could explain it.
But then wouldn't men also have it?

>>51182353
>sort of beauty standard?
Yes it is too, not just idols but most japanese girls you see in everyday life.
Also I couldn't find for the image for the life of me, but I remember something about it being bad posture for incontinence, I guess it makes it easier for them to take that fat load from the back.

He means that's just how she's standing, not that she has bad posture. There is nothing wrong with her legs.

bad nutrition growing up, not enough green vegetables

orientals are dysgenic

Don't Japanese have some kind of fucky skeletal structure compared to gaijin where the women tend to have shorter, stumpy legs and long torsos? That has to affect their ambulation and sitting posture, which would cause such a deformity
But not all idols are like this, very few gravure models have fucked up stances like this.

height is mostly leg length, anyone who is short has stumpy legs

>>51182353
You can literally see in the pic you posted that they are turning their right leg inwards to make it look like that. Its on purpose to make themselves look more delicate, even most vtuber models do it as default pose.

It's called being knock-kneed and it's the opposite of being bowlegged

That was one of the first things I noticed in Yoruami Coai

I know their hips are angled differently as one of the skeletal features of east asians, which is why their asses look so flat half the time despite containing the same amount of fat as western women, but I've never really heard anything corelated with leg length.
