The term "keri waza" is often used when referring to techniques against kicks in aikido. Actually this term means kicking techniques. In aikido this would mean kicks we do as techniques (atemi waza). When we talk about "keri waza" in relation to Aikido, we mean techniques that are used when uke is attacking with kicks. Any suggestions?
Not sure if I follow you, but I think you mean techniques like "Ashi Yonkyo"
Yonkyo applied to the ashi.
Hope that helps.
