He's guessing she wasn't supposed to know how to do that already.

"Awwww, how'd you do that so easy Chihiro?"

"Gather chakra in the feet, then walk up the tree."

"People who aren't naturally gifted at chakra control might need a little more help than that," Kakashi says. "Why don't you hop back down and give your teammates a few pointers?"

"...Understood." She jumps down and lands lightly on her feet.

"So! What're you doing different?"

"In order to assess that, I first need to know what you are doing."

"I'm putting chakra in my feet. Only a small bit, though."

"Show me."

He channels chakra and lifts up his foot. There's not really a glow, but there's definitely distortion and shimmer around his foot.

"...Show me as little as you can make."

"Uhhhhhhhhh..."

He can do very little extremely unreliably; his chakra inevitably flares back up.

"Try practicing with your hands first."

"Like, walking up on my hands?"

"Focusing the chakra in your hands. That is generally easier than the feet."

"Okay!"

He seems to have a bit less trouble with this, but his chakra's still not really behaving.

"...Try making some shadow clones to decrease the amount of chakra you are managing."

"Alright."

He makes about a dozen, and does, in fact, seem to be having much more success.

Kakashi, hidden behind his book, raises an eyebrow.

Sugira's by now gotten to a low branch. He sits to watch them, and says, "Try grouping your clones and having them work on different things."

"Uh, like what?"

He shrugs. "It's your brain. Suggestions, Kakashi?"

"Think about what individual pieces make up each action. If you can't do them all at once, work on one at a time."

He hums, sets one clone to thinking, and has the others start splitting up. These can just keep doing what he's been doing with running at the tree, these can (on Sasuke's advice) start trying to stick objects to their feet, those take off the shoes and also do the running thing (also on Sasuke's advice), those ones can split into more and more clones until they have little enough it's easier...

He should have picked a bigger training field. Eh.

If Chihiro and Sasuke have the basic idea down, they can practice it while he chucks kunai and shuriken at them.
