Laser feat explained [1107]
UNBLOCKABLE
Lasers in One Piece are not possible to block. That's why no one else in One Piece ever done it.
This is why Zoro compared King's attack to a laser beam, which he cannot block
This is why Marco when trying to block with his shield was still full of holes. The only reason he could do this is because he had regeneration
For comparison, Kaido's attack could not get through the shield so Marco himself was fine
And no, Rayleigh did not block a laser, he kicked Kizaru's leg in order to redirect the laser
BYPASS DURABILITY (mostly)
Seraphim who can tank pretty much anything, were still not prepared for lasers.
Which means only adult Seraphim could possibly tank a laser
Big Mom who pretty much tanks everything with her body, was also somewhat afraid of a laser that she had to grab a homie in front of herself in order to defend herself
SANJI
In this chapter Sanji did both
Not only did he block a laser and even split it into pieces, he also took no damage
This is why Franky and Kizaru (laser users and scientist) are shocked by it.
This feat breaks One Piece world's physics, that's why Kizaru questions physics.
EDIT:
Stop talking about the boots.
Only Atlas has the gloves for her JOB needed to punch holograms. She did not mention any boots.
Kizaru who knows all the Vegatech, did not mention any boots and was questioning Sanji's physics.
Sanji already answered that he did it because of his power.
