Fourth Element Tech Scuba Diving Fins
- Natural rubber heel strap
- Stainless steel spring strap
- Soft foot pocket. Hydro-flow vents
- Turbulence disruptors
- Strengthening ribs. Stiffening lateral rails
A classic vented fin, redesigned to maximise performance. Utilising natural rubber in a unique density gradient, this fin delivers a comfortable foot pocket combined with optimised stiffness for finning performance. The vented design allows water to flow along the blade reducing drag and fatigue, whilst the stiffening rails and ribs ensure that the blade of the fin is driven through the water to maximise the return on effort.
