The men's record for the 100m hurdles wearing swim fins is held by Jamaican athlete Orlando Vaughn with a time of 14.82 seconds. He set this record in 2017 during a fun competition organized by Olympian and world champion hurdler Derval O'Rourke.
Generally speaking, you need to use open heel fins if you are intending to wear either wet suit booties, or a dry suit. Closed heel fins can only be used on bare skin (or maybe wearing socks), so cannot be used when you need to wear exposure protection on your feet in colder water. But not all divers prefer open heel fins - when I dive in tropical waters, I much prefer closed heel fins, as they are lighter and I don't have to carry booties.
Free diving has several divisions for competition, each with its own record. The records can be found by using the link to our friends at Wikipedia and scrolling down.
This is called free diving and there are different classes. Jumping in with only your swimming suit and swimming down as far as you can and back to the surface is the most difficult and the record is about 100M. There are various others like wearing fins, going down a line with a weight, coming back up with a float. The one with the deepest records uses a weight to drag you down. The record for this is 275M (Goran Colac 2011). As this is a competitive sport this record will probably also be broken in time. There may have been deeper dives but they may not have been accredited and probably a lot of much deeper ones where the diver didn't return to the surface...
There are a wide range of different fins available for scuba diving. Other than dive fins, these include fins such as snorkel fins, paddle fins and split fins.
