IST FRA01/F Fathom Blue Full Foot Fins

Fathom Blue is a purpose-built apnea diving fin (free diving / spear fishing).

The comfortable foot pocket and powerful blade provide efficient thrust and unparalleled underwater maneuverability. Furthermore, there are two blades with different flexibility available to suit different divers' preferences and requirements. Although more expensive, rubber is our chosen material to make Fathom Blue’s foot pocket . It 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.


  • Blade dimension - effective (H × W): 22cm × 60cm (8.5” × 24”)
  • Overall length: 92cm / 36” (size XL)
  • Weight (pair, land): 1.9kg / 4.2 lb (size XL)
  • The gray blade is more flexible and less demanding, thus enabling the diver to flip through water quickly.
