Same thing happening here.... hair keeps sprouting in new places on my back and slowly spreading out from my stomach region, but lower legs, the hair is almost all gone.
It's almost a sign of youth to see very hairy lower legs: it seems to be something that signals "I am 15 going on 16" and then as the hair falls out, it signals "I am 40 or over". We can diguise our age, guys over 40, by wearing very tall socks and just revealing our hairy knees and thighs.
