I noticed a very unusual movement when watching a video of Yoko Okamoto Shihan during a morotedori attack (2 hands grabbing wrist). In my limited 3.5 years of (Aikikai) aikido experience, I have never seen anyone else place their feet like that. I tried it out in our dojo and it is surprisingly effective. Below is a link someone else posted of her teaching and demonstrating what I am talking about. Does anyone else do that? Is this "common"?
I can't say what is usual because that varies from place to place, but it looks very similar to the kind of footwork I'm taught. Just to be clear though, how would you describe the footwork you're speaking about?
