Is not part of that due to the kind of foot attire? I'll grant you a bit of female differentiation, but there can be some quite identical walks across gender, especially when carrying a load or athletic builds come in. Again, where ther are genrealizations, there are arguments against them.
It's no great secret that we have sixual dimorphism in our species. My anthropology classes in college taught me many of the ways we differ, and the pelvis is the big one.

Thirty four healthy volunteers familiar with treadmill running agreed to participate in this study (Table 1). All subjects were either experienced runners or regularly participated in aerobic conditioning. Subjects were excluded if they reported prior surgery to lower extremity or back, and/or had current pain during normal walking and/or running.
Females displayed signi?cantly greater non-sagittal hip and pelvis motion during walking and running across a range of speeds and inclines, whereas sagittal motion at the hip was consistent between genders. In addition, gluteus maximus activity was consistently greater in females during walking and running, while gluteus medius activity during the terminal swing–initial loading of running differed in response to speed between genders...
Speci?cally, gluteus maximus activity in females was approximately twice that of males...
I'm not supporting or defending anybody who wants different animations just so women are portrayed as "sixy". These ideas are quite grotesque. But I am defending the original point of the OP, because technically males and females
should have different walk/run animations. People who say otherwise have no basis other than "Bethesda has more important things to do". With Havok Behavior it could take them 5 minutes to modify the animation for females. You import the male animation, adjust the hip swagger a bit, that's it. They have to differentiate the females after all to load a different body mesh. At the same point they probably also point the mesh to which Behavior file it should use. Wouldn't take that much work.
Edit: And specifically, as I said in my first post, I'd like to see animation differences between species. Cat and lizard folk should move a bit differently. For that matter their body meshes should differ significantly.
