<p>As far as I remember, nothing has ever mention about how can Sanji and CP9 do this technique, but it's not haki. None of CP9 members are haki user.</p>

<p>One possible way to do this is they running so fast until they reaching considerable speed that they can put a step mid air, it first happen to Sanji when he was trying to run away from okama every day while training in Kamabakka Kingdom that he reach at a speed when he can do the "Sky Walk".</p>

<p>One other theory is it has the same principal with "Soru". This is one of the six techniques of "Rokushiki" that allows the users to move at extremely high speeds so people can't see with normal eye. It was revealed that the principle of this move was to kick off the ground at least ten times in the blink of an eye.</p>

<p>They are using one of the <strong>Rokushiki</strong> techniques.</p>

<p>The Geppo allows the users to actually jump off the air itself,

<p>How can CP9 members and Sanji(post-timeskip) run and stand in the air? Do they use something like Haki? If not, what kind of techniques do they use? If it is Haki, can Luffy and Zoro run and stand like they do?</p>
