As the title says Naruto cannot react to Sasuke's teleportation speed.
Why?
Naruto even with his sensing abilities didn't even know Sasuke teleported:
Notice the exclamation mark
Here we have Madara who has the same "floating" ability as Naruto, and is dashing at high speeds towards Sasuke but still got a sword through the chest meaning even he couldn't react:
Madara couldn't even react to Sasuke's foot speed:
There's a possibility Sasuke could have just used continuous teleportation but regardless of what he did Madara wasn't able to react.
Even in yesterdays chapter, Naruto was this time watching Sasuke as he was about to fall into lava. But notice the exclamation and question mark on the 3rd panel:
Though you could say Naruto wasn't able to stop flipping, but he still could have used chakra arms to grab Sasuke so Sasuke wouldn't have needed to grab his foot, but that's only if he had sensed Sasuke coming from behind.
To conclude, you cannot react to something that is instant.
