About Cressi Reaction Pro Full Foot Fins

Reaction Pro is the most recent Cressi Full Foot Non-Vented Fin which has been developed after the Rondine. The Reaction Pro is an innovative fin in look and performance. The Reaction is molded using the exclusive and patented Cressi system with 3 materials. The three materials consist of a comfortable thermo-rubber (elastomer) anatomic, computer-designed foot pocket. The foot pocket encompasses the foot assuring transmission of the leg-to-fin thrust without loss of energy, adding efficiency to the fining action.

The second material is the revolutionary new dual density (techno polymer) polypropylene which forms the blade, and in conjunction with the third silicone based material creates a channeling effect. The channeling effect is the characteristic of the fin that enables a high level of energy to be transferred in both up and down strokes of the kick pattern. The blade originates from the upper part of the foot pocket, with a 20% increase in useful surface area compared to a traditional fin of the same length. The blade also has a differentiated thickness and gets thinner towards the edge to guarantee greater and more uniform bending.

The side stringers are made from two different materials that alternate with each other and overlap in different zones to obtain a structure with controlled flexibility in the different areas of the blade. To all these excellent features, Reaction Pro adds a new, longer, more flexible and lighter blade that provides excellent thrust with minimum muscle fatigue and the smallest expenditure of energy. Fin is available sizes US 3.5-4, 5.5-5, 7-8, 8-9, 10-11 and 12-13 (EUR 36/37, 38/39, 40/41, 42/43, 44/45 and 46/47) and comes in Blue or Black colors. The Cressi Reaction Pro Fins are covered by a 12 month limited warranty.

The Cressi Reaction Pro Full Foot Fins is commonly used for Recreation, SCUBA, Snorkeling, Travel and more. The Cressi Reaction Pro Full Foot Fins is most used by customers who consider themselves to be a Advanced, Casual/ Recreational among others. The Cressi Reaction Pro Full Foot Fins is popular because customers like the following qualities of the Cressi Reaction Pro Full Foot Fins: Comfortable, Efficient, Lightweight.

Best for Free diving or scuba diving

I bought these in the hope I could use them to either snorkel, free-dive, or scuba. They are excellent for diving and free diving, but are too much for snorkeling. Although you'll see these listed here when searching for a snorkeling fin, I would NOT recommend them for that. Cressi does not list them as a snorkeling blade. A softer, smaller blade requiring less effort and a higher kick cadence is better for snorkeling. I have a pair of Cressi Rondine Palau(closed foot) that I find are abou...

Way too small

My foot size is 13. The largest size should fit, but they don't even come close. Also, there are two ridges on the top of the foot and those make the foot pocket even more uncomfortable. Never made it to the water with them. If your foot is large, these are not for you.

great fins


from Brooklyn, NY, US

These are excellent fins. They're stiff and take a little work to walk in (if you're doing a giant stride) but for back rolls off a boat off a boat they're fine. As for diving - well these are fantastic. They have nice thrust and can definitely stand up to swimming in current. Makes doing a modified frog kick a lot less work. Even if you want to do regular fin kicks, they're great. Just fold down the heel and slide them on like a slipper.


Cressida Fins


from Briarcliff Manor, NY, US

Underwater rocket boosters! Great Fins for the advanced diver. Long, but not too long for any type of water sport.


Great Full foot fins


Purchased last year after previous fins foot pocket tore during dive trip. These are the fins that the resort used for rental gear, so I knew what I was getting. Not as easy to kick some of the split or hinged designs, but I know they are quicker and more powerful when you need it.


Very Nice!


Got These for traveling. Worked Perfect


These Fins are a Work of Art


My daughter has to have everything color coordinated to have maximum impact as a fashion statement, even underwater. I, on the hand, am strictly interested in functionality, performance and design. We both couldn't be more satisfied with the Cressi lineup. Her new mask, snorkel and fins fit perfectly and perform beyond expectations and the bright yellow color match on all 3 items is perfect. I would also agree with those who say they run large. My daughter wears 8.5-9 woman's shoe. She ended up with the 3.5-4. Her foot is more on the thin side.

Shopper  Why Did You Choose This?
Timothy A  It isn't just how it is researched and how it is made, it is where and by whom. Visit a factory of your favorite gear company. It is about quality of life for everyone. Cressi is number on in this business.
ANDRES M  good trust with minimun effort
deneb k  I wear a US women's size 9 but read a review saying they run large, and another buyer who bought a US women's size 9 ended with a 3.5/4. I'd say I'm a regular 9, what do you suggest?
KEVIN F  They do run a little big. But also, the sizes listed are men's sizes. You can see the equivalent women's sizes on the size chart on the product page. You should be either a 5.5/6.5 or the 7/8 depending on width.

Mike T  Hi Tom, I would recommend size 8/9
SGT TRACY W  I wear a size 10 shoes and my fins are size 5-5 1/2
