The proper way to execute oi-zuki is to use the momentum of the body to shift the feet, keeping a low center of gravity while using the knife edge of the foot closest to your opponent to seek out the proper position (on a straight line, creating jigotai-daichi). The foot should be kept as close to the deck as possible without dragging it during this transition. Once the feet are rooted down, locking into place a solid jigotai stance, that triggers the release of the punch (explode the technique) straight into your target. Arigato, Kyoshi Robert Scaglione
