Cetma - S-Wing - Black

The innovative S-WiNG foot pocket is designed with a rubber compound that combines the high elasticity of natural rubber with the hardness of thermoplastic. The result is a material with a density of 1.05 (grams/cubic centimeter), which means that the foot pocket is almost 100% neutral in water.

The combination of S-WiNG foot pockets and Cetma's carbon blades means that the sole of the foot pockets is practically completely supported, as the fin blade reaches all the way to the heel in the foot pocket. The part of the fin blade under the foot is approximately 60% longer than on conventional foot pockets. This significantly improves both the power transfer to the fin blade and comfort.

Like a ski boot, the S-WING foot pockets have stiffening bands located along the entire length of the foot (from the big toe to the heel). These ribs allow for optimal transfer of the force applied by the swimmer, without any loss due to rubber deformation.

The S-WiNG has a rigid sole that prevents it from deforming under the load of the fin blade. The rigidity of the foot pocket allows the fin blade to be perfectly held under the foot, improving efficiency by approximately 30%.

The foot pocket is designed with two vertical stabilizers, which in addition to stabilizing also help channel water away from the fin blade in the most efficient way.

The front structure of the S-WiNG foot pocket is designed with a reinforced U-shaped structure that stabilizes the blade and prevents it from rolling during fin production.

The Cetma S-WiNG fits almost all feet, from size 35 up to size 48.
