The 'spoon effect' refers to the significant flow convection created by the unique arched profile and central ribs of the fins. This effect stabilizes and amplifies propulsion, making your dive smoother and more efficient.
The Cressi Thor EBS Fins are crafted from high-quality plastic and rubber. The blades are molded from two different materials to enhance reactivity and performance while underwater.
The Elastic Bungee System (EBS) ensures a perfect fit for all foot sizes. The EBS strap is coated with anti-corrosive rubber and features a large heel grab loop, making it easy to put on and take off the fins, even with thick diving gloves. The bungee design also adapts to your foot depth, counteracting the neoprene compression of your boots.
The under-blade foot pocket design ensures rapid transmission of applied energy and superior structural rigidity. This feature enhances the performance of the fins, making your diving experience more efficient.

I have size 9 Cressi Isla boots 5mm, and the fin's size chart states that I would need a Large. Regrettably, this is incorrect. I had to replace the fins for Small/Medium size, as the strap was barely putting any pressure on my heel and would have almost certainly fallen off.

Thor Fins

Best fins ever!

Brand new design for this extremely effective and yet very easy to use fin. The special arched profile of the fins combined with the two central ribs promote a significiant low convection effect, known as “spoon effect”, which stabilizes and boosts propulsion. Two lateral holes discharge the negative forces typically associated with this area and at the same time make for enhanced stability. The blades are moulded from two different materials for improved reactivity. These fins are perfect for scuba diving, whether you are an experienced diver or a novice.
TECHNICAL FEATURES
-The new Thor fin has a peculiar and unprecedented structure
that combines the two central ribs in high modulus
polypropylene, very reactive and a central area of the
thermoplastic rubber with a convex section, assembled in a
polypropylene blade.
-Two lateral nozzles, located in the area where the exion starts,
release the associated negative forces and allow the use of two
high-response ribs.
- Made using the exclusive 3-material injection system patented
by Cressi.
- Foot pocket increased by 5%.
- Under blade foot pocket.


It provides an excellent combinationof strength, power,
comfort and aesthetics and the optimization of the
requirements of each area of the fin.

Cressi has developed this special strap to meet the
needs of the most demanding divers, who need a
comfortable fastening for their foot but one that is still
practical and manageable.

The blade comes directly from the top of the foot pocket,
solidly joining The fin to the foot and transmittingall the
effort generated by flapping Without loss of energy through
soft areas.
