Reaction Pro Fins

£47.00 RRP £54.00 In Stock

Brand: Cressi

Model: Reaction Pro Fins

SKU: 9651-2

The Cressi Reaction Pro Fins are a perfect all-round snorkeling / scuba / apnea fin that is lightweight and efficient in the water. The Tri-material design channels the water straight to the tip of the fin for an efficient fin kick.


Three materials are used create the fin:

  • A soft and comfortable material in the foot pocket and side reinforcement bars to prevent rubbing and also to help protect the fin from bumps and knocks against other objects.
  • A rigid polymer is used in the main sections of the blade to provide structure and strength to control the shape of the blade during kicking.
  • A flexible silicone based material to give flexibility between the rigid panels, allowing the blade to form the channel shape.

The blade has been designed to be thicker near the foot pocket to provide strength and thinner at the end of the blade for flexibility. This ensure the blade flexes at the just the right amount over the whole length of the blade. If the blade was too think near the foot pocket it would flex beyond an efficient angle and lower the performance of the blade.


The blade of the fin has been positioned at the top of the foot pocket. This instantly increases the working area of the blade, resulting in greater performance but also less stress on the ankle and foot as you kick.

These full foot fins can be worn with bare feet, for a more comfortable and warmer dive you can wear the Fourth Element Finsock which reduce the chance of blisters, allergic reactions, cutting feet entering/exiting the water and having cold feet when you're in the water.

Cressi Reaction Pro Fins - Features

FeatureProduct Specification
Blade Type
Advances in design, materials and manufacturing techniques has allowed the development of various differenet types of fin blades which control the movement of water in different ways.

More advanced blades, including split and hinged blades, can dramatically increase efficiency, helping to improve propulsion but also lower the amount of energy required to operate the fins. Close.
Fin Length (mm)
The overall fin length of a medium sized fin Close.
Fin Weight (Pair kg)
The overall weight of a pair of medium fins including buckles and straps Close.
Foot Type
Fins are available in two fitting types, open heel and full foot pocket.

Open Heel are typically used for scuba diving as they are able to provide better propulsion due to their increased strength and weight.

Full Foot Pocket fins are usually worn by snorkellers who produce significantly less drag when moving through the water compared to a scuba diver. As a result the fins are generally smaller and much lighter. Close.
Full Foot Pocket
Quick Release Buckle
Quick release buckles aid fitting and removal of the fins by allowing rapid fitting and release of the fin strap.

Rather than having to loosen the fin strap off before pulling it over your heel to remove the fin, the quick release buckle allows you to disconnect the strap and slide your foot straight out. Close.
Strap Type
A number of different fin strap styles can now by found on fins including the traditional adjustable rubber strap, metal spring straps and also bungee straps.

Rubber straps can be easily adjusted to suit each individual diver and are typically fitted with quick release buckles.

Spring and bungee straps are generally not adjustable and are sized to suit the fin size, however, they offer an extra level of comfort and flex better during the kick motion. Close.

Good fins

Relatively light so OK for taking on holiday. No problems after a week long live aboard using these with Waterproof branded neoprene socks and rubber on soles makes climbing the ladder at the back of the boat easy.

These were listed as snorkeling fins

These were listed as snorkeling fins. They are far from it. They are far too rigid to be considered good for snorkelling (especially in Irish Waters). They are more like entry level diving fins.
