Le S-990 Firestone are fins 100% carbon of the brand new line 200 by C4. The blades are made with a progressive lamination of 4 different types of carbon, combined on seven layers of fabric for optimized responsiveness and strength. They have a dovetailed end. I water rails have been glued and overmolded at high pressure and temperature, this allowed the polymer they are made of to fuse with the composite of the blade, so as to avoid unwanted detachments during freediving. Their variable geometry has been thoroughly studied to guarantee the protection of the blade in the area near the foot and to avoid load losses along the whole length. They mount 200 footpockets With black upper and red sole. Blades dimensions: 770 x 192 mm. Available in the following stiffnesses: 25 Soft - 30 Medium - 40 Hard.
