question off the top of my head: does anybody know if women in general have a different femur/tibia length ratio than men?

Just curious, because the leg warmers I just got (with a clear articulated knee) do not cover my ankle bone, which is a bit irritating, but go all the way (!) up to the top of my thigh. Otherwise they're well made, but maybe I just have long tibias. Or short femurs. Or something.
