Okay, okay, okay (sorry guys, lots of coffee today.):
Obvious this 'thickish' leg thing is genetic, duh, but is it possibly related to weak ankles?
Hypoth: weak ankles and feet burden the calf muscles with more work, and thusly more muscle/fluid/soreness/ugly.
weak ankles: when you feet are collapsing and rolling out of alignment with knee and tibia, can result in tibial torsion (permanent bent or twisted tibias that require one to use their feet incorrectly lest they walk duck-footed or pigeon-toed).
I'm noticing a strong correlation between folks with bad feet and ankles and bad legs, just like Sasha Luss and Elle Fanning.
^^kind of a confusing picture. the left pair of legs is correct because the knees and feet face the same direction, the right does not.
^^while Sasha's bones are definitely bigger, look at how her foot is angled and her ankle collapsed compared to the girl's on the left
