Being extremely mobile, avoiding and blending with the oncoming energy of an attack is a fundamental skill of Aikido. It is imperative that the Aikidoka move his or her feet aggressively, in order to maintain proper balance, distance and position. The feet are moved with tsukii-ashi, or sliding steps. The feet always remain in contact with the floor, so as to retain good solid balance.
The foot movements make up the first portion of what is commonly referred to as the walking kata. There are 3 sets of foot movements: front-to-back, side-to-side, and the four corners. Each set of eight movements is repeated twice.
Set 1: Shomen Ashi - forward step
Set 2: Waki Ashi - side to side step
Set 3: Tenkan Ashi - step feet
Unsoku allows us to develop understanding of and use these principles. Be where you are, not in front of the count, not behind the count but anticipating the count. As soon as you hear the count, you move; then you stop. When you hear the next count, you move; then you stop, etc,. Simple but very difficult. Each count is an isolated event; you are not bouncing through a set of eight moves times in three directions; you are practising 24 separate moves, put together for the sake of learning and preparation for Randori.
