When I walk, every step, my ankles crack. Walking up/down stairs its lowder, If I turn my feet in a circular motion, they crack. I remember that I used to sprain my ankles a lot when I was younger...
WTF is it? What can I do about it?
"The highest reward for man's toil is not what he gets for it, but what he becomes by it." -John Ruskin 1819-1900
"He who fights monsters should see to it that in the process, he does not
become a monster. And when you look into the abyss, the abyss also looks into
you." - Nietzche
Just ligaments, most likely. Mine do the same thing, except only when on stairs. There's at least six ligaments in the ankle that I can think of, probably more.
