Footwork differences between styles
I am curious as to the reasoning of the slightly different foot work between styles of Aikido.
I am learning a style based on Iwama, my Sensie spent many years training at Iwama. Our foot work remains very square. By this I mean that the front foot is "always" placed at a 90 degree angle to the back foot with the toes pointing forward. Having seen other styles at seminars and in videos the front font is often placed in approximately the same location but the front foot is placed with the toes pointed out and the heel in.
I was wondering if there was a rationalization behind the difference in foot placement.
