yeah they need to be screwed in to the proper glue-on base that is made for them, not directly into board inserts
I have them on my surfboard, they work well and my foot doesn't get stuck. They swivel a bit for easier toeside riding and don't get soaked with water. 
no they are the togue from that beer ad where the togue lept out of the guys mouth when he was asleep and went clubbin.
It woke up the next day on the beach after a big night out and tried to have sex with a surfboard.That photo is the result
So that makes them some kind of devious board thingy
