Features:
- Polypropylene blade: This material, inherited from apnea fins, has as its
main characteristic the very fast transmission of applied energy and its
great structural rigidity. It is applied to the shovel and inner area of
the sole sandwich. He is very nervous and reactive and facilitates a very
agile and effective flutter. It has a stress-performance ratio clearly
superior to traditional materials (natural rubber or thermoplastic,
polyurethane, EVA). Likewise, it has a great resistance to breakage to the
point that Cressi guarantees it for life for sporting use.
- The inclination of the blade with respect to the foot pocket has
increased by 5% compared to traditional diving models. This angulation
provides greater efficiency and a more natural foot position during
fluttering.
- Polypropylene of the high module: Especially reactive, it is applied to
the nervaturas of the blade and is responsible for providing rigidity and
return to the blade. This material connects the critical point of
transmission of energy (the instep) with the nerves in one piece, avoiding
the usual loss of energy through excessively flexible components of the foot
pocket that produce a heavy, slow and fatigue fluttering the instep.
- The two lateral nozzles located in the zone where the flexion starts
release the associated negative forces and allow the use of two ribs of high
rigidity.
- Flexible elastomer: It is applied to the foot pocket and the areas that
require flexibility and elasticity, since they influence the comfort of the
diver: Footrest toe, interior of the sole and area of the instep in
contact with the ankle. It is also assigned to the areas that require
non-slip capacity: Inserts in the sole (area in contact with the ground) and
anti-shock, such as the lateral nerves of the blade. The fusion of both
materials is done at the molecular level and its strength is guaranteed for
life for sports use.
- Central area of the thermoplastic rubber blade of convex section
assembled in the polypropylene blade.
- Shoes with three different volumes, with the central area narrowed so
that the foot remains firmly fixed in its interior and the transmission of
the foot-foot-paddle effort is direct and precise.
- Foot pocket reinforced in the upper area by a supplementary thickness
and laterally by two extensions of polypropylene from the upper to avoid the
dispersion of energy in the process of transmission from the foot to the
blade.
- Rigid sole with non-slip inserts made of thermoplastic rubber.
Description:
The THOR fin has a peculiar and unprecedented structure that combines the two
central ribs in high modulus polypropylene, very reactive and a central area of
the thermoplastic rubber with a convex section, assembled in a polypropylene
blade. Two lateral nozzles located in the area where bending starts release the
associated negative forces and allow the use of two high response ribs. This
combination causes a channeling and acceleration of water flow, which stabilizes
and increases propulsion at equal effort.
The inclination of the blade with respect to the foot pocket has increased by 5%
compared to traditional diving models. This angulation provides greater
efficiency and a more natural foot position during flapping.
Thor enjoys an exclusive system of injection of 3 materials patented by Cressi,
which offers a combination of strength, power, comfort and aesthetics and the
optimization of the requirements of each area of the fin.
Main body of polypropylene: This material, inherited from apnea fins, has as
main characteristic the rapid transmission of the applied energy and its great
structural rigidity. It is applied to the shovel and inner area of the sole
sandwich. He is very nervous and reactive and facilitates a very agile and
effective flutter. It has a stress-performance ratio clearly superior to
traditional materials (natural rubber or thermoplastic, polyurethane, EVA).
Also, it has a great resistance to breakage to the point that Cressi guarantees
its life for sporting use:
Flexible elastomer: It is applied to the foot pocket and the areas that require
flexibility and elasticity, since they influence the comfort of the diver:
Footrest toe, interior of the sole and area of the instep in contact with the
ankle. It is also assigned to the areas that require non-slip capacity: Inserts
in the sole (area in contact with the ground) and anti-shock, such as the
lateral nerves of the blade. The fusion of both materials is performed at the
molecular level and its strength is guaranteed for life for sports use.
Polypropylene of the high module: Especially reactive, it is applied to the
nerves of the blade and is responsible for providing rigidity and return to the
blade. This material connects the critical point of transmission of energy (the
instep) with the nerves in one piece, avoiding the usual loss of energy through
excessively flexible components of the foot pocket that produce a heavy, slow
and fatigue fluttering the instep.
It also uses several technologies common to the rest of the Cressi models.
"Shoe design under the blade": Now increasing its angle by 5%, the blade comes
directly from the top of the foot pocket, solidly joining the fin to the foot
and transmitting all the effort generated by flapping without loss of energy
through soft areas. This format allows the water to be channeled from the same
ankle to the final edge of the blade, unlike traditional models, in which the
foot pocket has no contribution to the advance. Apart from improving the
directionality of the flutter, this design provides a performance between 10%
and 15% higher than what would correspond to the fin for its blade surface.
Thickness of the blade of decreasing profile "spina di pesce" to improve the
directionality of the flutter and achieve a greater inertia of the final part of
the fin.
Foot Pocket reinforced in the upper area by a supplementary thickness and
laterally by two prolongations of polypropylene from the upper to avoid the
dispersion of energy in the process of transmission from the foot to the blade.
FOOT POCKET with three differentiated volumes, with the central area narrowed so
that the foot remains firmly fixed inside and the transmission of the
foot-paddle effort is direct and precise.
