Mares Pure Instinct Instinct Pro Spearfishing Fins

The INSTINCT PRO is the result of a meticulous design created by computer and the use of new materials.

The new shape of the highly-pronounced "V" blade prevents any risk of slippage. The foot pocket retains all its qualities of comfort and hold for the foot, and at the same time brings even more power to the blade.


  • The tapered-section blade, paired with a new technopolymer, has made it possible to achieve optimum results in terms of both power and thrust modularity.
  • The micro-ribbing on the blade optimizes efficiency.
  • The elongated lateral stringers have a tapered section designed to make the blade’s deformation progressive and to create a channeling effect with the water, the fin’s true driving power. Length is approximately 32 inches long but varies a bit by the foot pocket.

Well, the best is the Carbon Razor, the rest are other styles of the same in my opinion.

I have been looking into good fins for freediving and spearfishing and I have heard the Instinct pros are good for both. Are they?
