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. New up-and-over adjustable quick-release buckles allow ideal positioning of the strap on the heel. These new buckles locking system prevents the possibility of the buckle falling off, even if the fins are unbuckled. To all these excellent features, Reaction adds anew, longer, more flexible and lighter blade that provides excellent thrust withminimum muscle fatigue and the smallest expenditure of energy.

Comments about Cressi Cressi Reaction Open Heel Fins:
Very good fins. I used Mares Avantis and their Vol (something). I bought these because I need fins without heels to make beach entry. Ever since I haven't touched my old fins. These are GREAT fins for people in good shape. They are VERY stiff, but this allows for UNBELIEVABLE power, and if your in good shape you can become quite the scuba sprinter. The only possible down fall again is that they are stiff, so people that are out of shape or prone to leg cramps may find that these fins are hard to deal with.

Comments about Cressi Cressi Reaction Open Heel Fins:
These fins are sleek, lightweight and are uncomplicated. Be careful with regard to sizing--[...] I am a women's size 8-9 shoe and the size S fin is wayyy too big, even with a boot. I had to exchange them for an XS which is better. [...]

Comments about Cressi Cressi Reaction Open Heel Fins:
I have this in clear/yellow. This is a good fin and looks great.
Not really a complaint as opposed to something to consider, is the strap. These fins do not accept the universal spring straps. Cressi has a different clip system than most.
Also, Cressi does not offer spring straps.
Again, just something to consider.

Comments about Cressi Cressi Reaction Open Heel Fins:
I had been diving with Prolight Cressi fins with no problems at all until I bought these Reaction Cressi fins and I have no regrets.
I have now much more propulsion than before and
the layout is much nicer than the Prolight.
For divers that like more rigid fins , it is The option.

Comments about Cressi Cressi Reaction Open Heel Fins:
My wife and I bought these fins before going to Bonaire as an open-heeled fin is recommended due to wearing boots for rugged shore entries. The fins worked great, not too stiff, but not overly flexible either. Fins give good propulsion, and did not did not seem like "too much fin" for snorkeling as some other reviewers indicated. We have used primarily for snorkeling/free-diving but imagine they would work equally as well for SCUBA diving. Another criticism was the foot insert area being too big, we wear them with Seasoft boots and love them (read my review on them too if looking for a great warm water boot). Feet never cramp and I have spent multiple hours in the water at multiple points in the day (both in Bonaire and Roatan). Overall a great fin for a price that doesn't break the bank.

Very comfortable fins and they are a great price. Swimming is very natural. For a recreational diver I wouldn't see why you would want anything better.

Comments about Cressi Cressi Reaction Open Heel Fins:
Overall, these fins are great. My only complaint is they run too big. I wear a 6 1/2 womens shoe and the xs fin is still too big. I have to keep pulling on them to make sure they are staying on.

Comments about Cressi Cressi Reaction Open Heel Fins:
[...]s. I finally got around to buying a set of the reaction fins and I am very happy with these fins! They have great flex points and stuff points. I had these on my feet about 4 straight hours and no cramping or discomfort in any way! They are very quick to; the only problem I found can be good or bad. The foot pocket is very thick, tough but bulky and makes packing a bit more difficult but not bad. The good thing is they will resist flattening.

Comments about Cressi Cressi Reaction Open Heel Fins:
You will not confuse the foot pocket fit with that of a mares fin. The sole is arched upwards resulting in some odd sensations and loss of leverage on upstroke. Thin soled booties result in greater instability. Wear a thicker hard soled bootie.
Blade has nice progressive snap and works well with frog sculling. Clunky foot pocket design makes packing a bit more of a burden then other fins. Newfangled strap design (all plastic construction) will not accomodate stainless or save-a-dive straps.

Comments about Cressi Cressi Reaction Open Heel Fins:
Good fin. Not quite as fast or effortless as a good set of split fins, but I like them more than any other open-healed non-split I've tried. A little bulky for travel when the larger sizes are purchased.

Comments about Cressi Cressi Reaction Open Heel Fins:
I haven't had a chance to try these fins in true open water, however I've taken them to the lake and really liked them. They are a lot longer than my old DiveRite fins and will take some getting used to as I kicked up a lot of debris from the bottom. The speed I got out of the fins was incredible-they really allow for efficient use of kick cycles. One kick cycle and you're out of there!!

Comments about Cressi Cressi Reaction Open Heel Fins:
With approximately 200 dives logged and owning several pairs of fins, these are by far my favorite! They almost seemed too big at first since the botton of the fin sits at the heel of the foot instead of the middle of the foot. The fins feel like a natural extension of your foot! Like your not wearing fins at all yet you glide thru the water with ease! I don't feel the fatigue in my legs like I did with my other fins. I recommend them highly.

Comments about Cressi Cressi Reaction Open Heel Fins:
I didnt like these much, they were VERY stiff. After a few trial laps in the pool, my legs were beginning to hurt. For the leisurely snorkel week i was planning, they were not right.
