This simple move has a variety of applications:
- Nami-ashi is the ultimate defense against leg sweeps and stomp kicks to the instep or shin. A quick nami-ashi denies the opponent from having a target, reducing their attack into a shadow-boxing drill.
- Nami-ashi can be used as a transition to quickly change your direction.
- The up-stroke of a nami-ashi uses the ball of your foot to swat attacks away, to the inside, much like a sweeping block does with attacks to the midsection.
- The down-stroke of a nami-ashi uses using your instep as a hook to swat attacks away, to the outside.
- Nami-ashi allows you to use your lower leg as a defensive cover (i.e., a “meat-shield”), to protect your groin at the expense of your shin.
- Nami-ashi can be used to off-balance opponents in the clinch. If you and your opponent are pushing against each other, a nami-ashi can momentarily release the pressure without compromising your balance. Since the opponent continues to push, which effectively becomes a burst of forward momentum which can be used to augment blows or to setup takedowns.
