First off a disclaimer, I am far from one who needs or wants to tell people how or what they should do, so this is my observation. The first time I read this I reflected on not only how this has been on my mind off and on, but also what I noticed while in downtown Seattle for my Dr. visit. I sat in my truck and just watched both women and men and how they walk. I did this for a good 20 min or so and I noticed very few women who seemed to have a 'distinct' feminine walk. I thought, well the next time I go down there I will repeat this and I pretty much came up with the same conclusion but with just a bit more refinement. The more noticeable walk came from the older women (50+ years) and the younger (25 to 35) only a very slight difference with just a few. The most noticeble were the teens who seemed to walk most like the boys. Now here is where my observations could quite possibly be faulty, I may still be looking through the lens of masculinity and may be skewed, also the subtle difference could be just the simple matter of physiology. The exaggerated masculine walk was mostly in the young guys.
So now why I put on the disclaimer, does accentuating any perception of how a woman walks increase the likelyhood of being 'clocked', who knows, this is like I said just an observation.
