Intermediate hardness fin suitable for all fishing styles. The thermo rubber shoe was made with two different hardnesses, the green parts, those in contact with the instep and toes, have a hardness of only 40 sh, the black ones have a hardness of 90 sh in order to transmit without dispersion all the power impressed on the blades. An anti-slip tessellation has been created under the heel. The removable blade is made of low modulus polypropylene and is equipped with 2 "water rails" which eliminate the derapage effect.
