Esclapez is now owned by Immersion and they sell a few different models- different colors for different stiffness in blades. I happen to own a pair of the Black open heel fins for scuba diving- I can fit their XL size over a drysuit boot with my size 43 foot. They are decent fins for plastic, but you do loose some of the efficiency of a full foot pocket. Still, there are sometimes when an open heel pocket works better- like while scuba diving with a drysuit.

Other companies that make, or used to make, and open heel fins are Sporasub, Cressi sub and Zeagle- although he Zeagle ones were just re-branded Esclapez fins. You can find these on Ebay from time to time and I've owned all of them at one time or another- for scuba diving and not freediving.

I, believe, that you can order the Immersion open heel fins through Jimdoe2you- as he's the Immersion rep for the USA.
