A New Fin Concept
easier to walk 
Foot pocket
Manufactured from material of differentiated thickness, this solution
allows developing less pressure on the foot in the areas that are not
critical for good transmission of the thrust to the blade, thus offering a
more comfortable foot pocket while reducing possible cramps.
Connection between blade and stringers
It consists of a fl exible joint of differentiated thickness obtained from
the combination of overlapped semi-rigid and fl exible materials to a
variable extent. This solution aims to obtain a bending strength of the
blade proportionally increasing with respect to its relative bending
angle, thus allowing an optimum bending both with lesser effort and
with more strength. Furthermore, since most of the blade bending has
been concentrated in the connection area, the negative and neutral
thrust areas have been drastically reduced or even almost completely
eliminated to the advantage of a better performance, the power applied being equal.
Blade positioning
The blade is positioned on a level different from the foot pocket to keep
it away from any turbulence caused by the foot and the leg, so that it can work in a less disturbed area and allow the best performance.
Furthermore, the raised position of the blade with respect to the foot
pocket allows a better thrust during swimming since it is located at a
lower level than the blade of traditional fi ns, while assuring an easier
walk on land.
Blade features
Due to the different thickness and combination of various materials, the
peculiar structure and composition of the blade has been designed so
that it can be perfectly adapted to the best hydrodynamic form it must
have to guarantee the best thrust according to the power applied. The
end part, very fl exible and with minimum thrust function, directs the
threads so as to create the least turbulence.
The stabilizing fl aps, situated on the lateral sides of the blade where
the blade provides more thrust, make it perfectly directional. Furthermore,
unlike most other fl aps, they are perfectly parallel and based on
a hydrodynamic design, so that they offer the least resistance during
stride, thus assuring excellent fl ow direction and improving the thrust
performance.
