The Mares Pure Instinct Razor Pro Fin Blades are one of the best performing technopolymer fin blades available on the market for freediving and spearfishing. 

These fin blades are 63cm long and 22cm wide and will fit the Pure Instinct Razor Pro foot pockets. These blades are incredibly efficient due to the use of a modern polymer with the addition of elastomers, which combined, optimise elasticity and reactivity. The blade thins towards the tip, allowing for a parabolic flexion of the fin. 

The V tip prevents slipping of the fin in the water and the liner built for performance delivers a perfect power transfer from foot to blade.
