These fixed blade fins are characterized by their thermo rubber foot-pocket and for the angle between foot-pocket and blade being 22 degrees (compared to traditional 15/17 degree).
The use of thermo rubber of two different stiffness compounds increases comfort over normal foot-pockets.
The 22 degree angle is the result of trying to optimize the power of the push through the water relative to effort.
The blades are produced in a low modular polypropylene in medium stiffness.
Available in Euro size 39/40, 41/42 and 43/44
