When I went diving in august there was a diver who had these awesome fins. They were all black and they were almost shaped like bow ties. In the very middle where the toes are, they had what looked to be springs or coils. Then the actual fin was attached to this "spring". If anyone has any idea as to what I’m talking about, I would appreciate any help. Thanks in advance

My first guess from your description would be the Scubapro Seawing Nova fins.

My next guess would be the Aqua Lung Slingshot fins, but they look too much like a traditional fin to match your "bowtie" description that well.
