Like I wrote previously, the 180 degree turn Tai-Sabaki in Korindo Aikido is taught on the hills for beginners, as one becomes more proficient, the turn becomes full feet and one may even turn on balls of one feet if necessary. Amir
Well.. I haven't looked at footwork as much as I should have, and I always thought that turning on the balls of the feet was the way to go - you can see a good example of this by watching Osawa Hayato Sensei (the son of the former dojo cho of the Aikikai Hombu Dojo).
Having said this though, I happened to watch the DVD by Ikeda Hiroshi Sensei and he did mention practicing turning on the heels as well. So, I guess it's an alternative.
Whatever works best for you
