Fathom Blue is a purpose-built apnea diving fin blade (free diving / spear fishing). The  powerful blade provide efficient thrust and unparalleled underwater maneuverability.  Might seem a bit old fashioned but at the end of the day, it is all about performance. We were able to strategically build a rubber foot pocket with multiple flexibility / hardness while fins made from various plastic compounds do not share the same advantage. This means Fathom Blue's foot pocket is able to produce a spring-like effect when finning, yet its base (sole) is rigid and efficient.
