Since 2003, Jet fins. Scubapro, not clones or copies. XL, with spring straps (separate purchase). I'm now on my second set as the first set finally broke at the strap attachment point. I also now have a spare set, "just in case".
When I owned a suit with rock boots, I had to buy a pair of Turtles because nothing else had a fin pocket that would fit those boots, but I sold that suit and don't use the turtles now.
I also still have my very first set of fins I bought in 2000 - a set of blue Mares fins that I still use in the pool when teaching. Funny thing is they fit the rock boots very well, so I did use them for a time with that suit in the ocean.
