The approved foot pocket has been recruited with an innovative fin blade. Supported through the indicated Powerfins, the flexible middle part composes a water channel and maximizes the advance. The speed vents close by down beat of the fin and supports the Bernoulli-effect. By up beat the speed vents open up to decrease the water resistance - this results in intransigent power and effectiveness.
