s-WiNG Footpockets Black
1) Foot on carbon: the new s-WING footpocket by CETMA COMPOSITES enable long blade portion under the foot, using CETMA COMPOSITES blades the foot is totally layed on carbon blades. Blade portion under the blade is 60% longer than conventional blades. This feature improve the load transfer and comfort.
2) Sky-boot like: the design of the new s-WiNG footpockets includes several high-stiffness bands which are studied to hold the foot completely signed and constrained (from tip to big toe). This feature can be used to transfer the two driving forces to rubber deformations.
3) High stiffness sun : The new s-WiNG footpocket has a stiffened sun, this avoid deformation of footpocket sun under blade load, enabling the use of all kind of blades. The blade pouch stiffness allows the blade to be perfectly constrained and to increase by 30%
4) Open flow system: the new s-WiNG footpocket is designed to channel the water flow into a channel beside the foot, this "without spars" system has been studied to optimize the hydrodynamic efficiency.
5) Twinzer system: The new s-WiNG footpocket is designed with two vertical stabilizers which avoid the sideslip motion.
6) Anti-twist System: the front structure of s-WiNG footpocket is designed with a higher stiffness U-shape reinforcement to stabilize the blade and avoiding rotations in longitudinal axis.
7) Comfort: the new s-WiNG footpocket has been designed to maximize comfort by wrapping and following the foot shape of the foot anatomically, this thanks to 7 size available from 35 to 48.
8) Hi-efficiency Water rail: CETMA COMPOSITES well-known Hi Efficiency water-rail minimizes the rubber content to increase the efficiency of the blade
9) No Weight material: material used for s-WiNG footpocket is an innovative rubber blend combining the high elasticity of natural rubber with durability of thermoplastic rubber. The results is a material density of 1.05 (grams / cubic centimeters) which means no weight in the water.
Why does the s-wing shoe dont have side rails, unlike all the other shoes?
Answer: The rubber shoe with the side rails belongs to an old concept of liner developed for plastic blades. The side rails served to give the blade a stiffness gradient. In carbon blades, where it is possible with a correct design to distribute the stiffness by working on the rolling sequence, the side rails are no longer needed. On the contrary, they have the extremely negative effect of acting as dampers, jeopardizing the correct operation of the blade for a good part of its length.
