The la chancla thing is fucking moronic, who the hell takes off their footwear to beat someone, why not just keep a beating stick nearby
It takes more effort to take off your sandal than grab literally any other nearby object
You have one less shoe on so if they run now you're chasing them at a disadvantage
It's like those dudes who rip off their shirt every time they think there's going to be a fight except with even less logic
Beating your kids with a belt I can understand, a belt is like a whip and is more painful, it's a specific tool that you're less likely to have just lying around the house, but a sandal is such an ineffective thing to hit someone with it's ridiculous
