Cressi Rondinella vs Cressi Palau: Full Foot or Adjustable Open Heel for Snorkeling?

The short answer is that the Cressi Rondinella and the Cressi Palau are both snorkeling fins, but they solve different problems. I own the Rondinella. I have not owned the Palau. I have used the Rondinella for two summers, about 40 outings, all of them barefoot beach snorkels in 3 to 8 feet of water inside a marked swim area. For that job, the full foot pocket is simpler and I reach for it without thinking. For travel, for a boot, or for a foot that sits between sizes, the Palau's adjustable open heel is the better answer. That is the whole comparison in one paragraph, but the details below are the part that matters when you are standing at the water line.

I am 61 and I dive and snorkel out of Tavernier, Florida. My Rondinella pair is blue and lives in the back of the 4Runner from May through September. Every outing runs 45 minutes to an hour. After about an hour they rub the back of both heels, so I come in. They fit from the first afternoon, no break-in. The Palau I know from its published listing only: adjustable open heel, quick-release strap, built for travel. I have not handled it in a shop and neither has anyone I dive with, so I will not pretend to know how it feels on a foot. I will tell you what the listing says and where that leaves a recreational snorkeler.

Where Cressi Rondinella Wins

The Rondinella wins on simplicity. There is no strap to adjust, no buckle to fight and no hinge at the ankle. The foot pocket is coalesced with the blade, which is Cressi's way of saying the pocket and blade are molded as one piece. You pull it on with the heel tab and you are done. On a beach entry, that matters. I walk in, put the fins on in waist deep water and swim. Nothing needs a second look. When I come out, I pull the tab and step out of them. There is no strap to loosen first, and no buckle to rinse sand out of.

The blade is soft and flexible polypropylene, and the fin is light. I am not going to tell you it will push you through a running tide, because it will not. I met one tide in these and turned around at once. But for the long, easy surface swims I do, it gives enough thrust without burning my legs. The 2-year limited warranty and the made in Italy line are both on the listing, and both are worth more to me than a fancy graphic. The blade is also the reason the fin is easy on a tired leg. It is not a stiff scuba blade and it does not pretend to be.

The Rondinella also wins on the amount of information Cressi publishes. I know the weight, the material, the closure type and the warranty from the listing. I know the foot pocket is pull-on and the blade is polypropylene. That does not make it a better fin than the Palau. It makes it a fin I can describe without guessing. When a listing gives me that much, I trust the rest of it more. When a listing is thin, I wait until I can put my hands on the gear.

Where Cressi Palau Wins

The Palau wins on fit. The open heel has an adjustable quick-release strap, so the fit can be adjusted. If your shoe size lands between two sizes, or if one pair has to work for more than one person, that strap is the reason to pick it. The Rondinella cannot do that. It is sized by shoe and the pull-on pocket is the whole fit system. On the Rondinella, if the pocket is tight across the top of your foot, you do not have a strap to back off. On the Palau, that is exactly what the strap is for.

The Palau also wins on travel. Cressi lists it as built for travel, and the quick-release strap is the part that makes sense for packing and for getting fins on and off on a boat. I have not owned it, so I cannot tell you how the strap sits after a week of daily use. I can tell you that on my old open heel fins, a buckle strap was the part I fought with. A quick-release strap is a better answer to that problem than a buckle. If you fly to your diving and the fins go in a bag, the Palau is the one of these two that Cressi built for that job.

The open heel is also the reason the Palau can do more than one job. I wear 3mm Cressi boots with my open heel scuba fins, and an open heel snorkel fin can be worn the same way. The Rondinella cannot. It is barefoot only for me, and I have never worn socks with it. That is not a fault. It is the design. But if you want one fin for a boot and a bare foot, the Palau has the hardware for it and the Rondinella does not.

What the Full Foot Pocket Changes on a Beach Snorkel

A full foot pocket is a closed shoe. Your heel sits inside the pocket and the pull-tab gets you out. There is no strap across the back of your heel, so there is nothing to loosen, tighten or replace. That is the whole appeal. On a barefoot beach snorkel, in calm water, with a known shoe size, it is less gear to think about. I do not have to check a strap before I push off. I do not have to rinse a buckle. I pull them on, swim, and pull them off. For a 45 minute to an hour swim, that is the right amount of gear.

The trade is that the fit is fixed. I wear mine barefoot and I have never worn socks with them. If the pocket does not match your foot, you feel it at the heel or across the top of the foot. Mine fit from the first afternoon, but that is one pair of feet. Check the pocket against your own foot before you commit, the same way you would check a mask skirt. A full foot fin that is too tight will not get better with use. It will rub. A full foot fin that is too loose will not give you the thrust the blade was made for.

After about an hour in the Rondinella, the back of both heels rubs. That is the fin's honest limit for me, and it is why I stop at an hour.

What the Open Heel Changes

An open heel fin has a strap across the back. That lets the foot pocket be more open, and it lets the same fin close over a neoprene boot. The Palau's strap is a quick-release type, so you are not working a buckle with cold hands. For a travel fin, that is the right set of choices. It is listed as a travel fin, with a strap you pull to release it. The Rondinella is simpler, but the Palau is more adaptable. That is the trade in plain terms.

The trade is more parts. A strap can loosen, rub or fail, and it is one more thing to check before you step off. I am not saying the Palau's strap will fail. I have not used it. I am saying that any open heel fin has a strap, and a strap is a wear item. On my old open heel fins, the buckle strap was the part that gave me trouble. That is the kind of maintenance an open heel fin asks for. A full foot fin does not ask for it because it does not have a strap.

Fit and Care Notes

The Rondinella is pull-on, so the fit is the shoe size. Cressi lists a 2-year limited warranty. I rinse mine at the carport rinse tub after the drive home and lay them flat in the 4Runner. They have not cracked or gone soft in two summers. I do not leave them in direct sun if I can help it. The heel tab is the part that gets the most use, and it has held up. The blade has a few scratches from sand and limestone, but nothing that changes how it swims.

The Palau's quick-release strap is the part I would rinse and check. I cannot tell you how it wears because I have not owned it. I can tell you that on any open heel fin, the strap and the buckle point are where salt and sand collect. Rinse them, look at the strap, and replace it when it starts to look tired. That is not a knock on Cressi. It is how open heel fins work. A quick-release strap is easier to use than a buckle, but it is still a strap, and it still needs a look now and then.

What Neither Listing Settles

Neither listing settles the fit on your own foot. I can tell you the Rondinella fit me from the first afternoon, but that is one pair of feet. I cannot tell you the Palau will fit you, because I have not worn it. The Rondinella is sized by shoe and has no adjustment. The Palau has a strap, but a strap only changes the tension across the back of the heel. It does not change the length of the pocket. If the pocket is wrong, the strap will not fix it.

Neither listing settles how the fin swims for you. I know the Rondinella is soft and flexible and light, and I know it is enough for my surface swims in calm water. I do not know how the Palau blade feels, because I have not used it. I will not rate it from a photograph. If you are choosing between the two, use the design to narrow it down, then use the fit to make the final call. The design tells you whether you need a full foot or an open heel. The fit tells you whether that specific fin will work on your foot.

Who Should Buy Which

Buy the Cressi Rondinella if your snorkeling is barefoot, from a beach, in calm water, and you know your shoe size. It is the simpler fin, and the one I use for 45 minute to an hour surface swims in 3 to 8 feet. I would not buy it for scuba. I use open heel fins with boots for scuba, and the Rondinella is not part of that kit. I also would not buy it if you plan to swim against a current. It does not have the blade for that, and I turn around when I meet one.

Buy the Cressi Palau if you travel with fins, wear a boot, want an adjustable strap, or have a foot that sits between sizes. It is the fin I would look at first for a trip where one pair has to do more than one job. I have not owned it, so I am judging it from the listing, the same way I judge any gear I cannot put my hands on. The listing says adjustable open heel, quick-release strap and built for travel. Those are the right features for that job. If you want the full foot simplicity and the Rondinella pocket fits you, I would still take the Rondinella for a barefoot beach day.
