Would this work for Weever fish? My father in law was stung while walking the beach last year in Portugal, and I've been looking for some sort of sea shoes to bring with us since
This is my first time hearing about weever fish! Reading about them online, my best guess is that yes, our booties probably would work for them! The mechanism is very similar to stingrays, and they are a similar size to the ones we test with (round rays, about dinner plate size). To be clear, we haven’t explicitly tested with weever fish, so it is just my best guess.
Portuguese here, I know people that wear Crocs for that reason.
I have been lucky and haven't been stung in 30yrs of going to the beach here. As far as I know it's a bigger danger when the water is warm, but this might be just a myth.
