IST FRA01/F Fathom Blue Full Foot Pocket Apnea Free Diving Spearfishing Fins are purpose-built apnea diving fins specially designed for free diving and spear fishing.  Time tested technology in a sleek and modern design to provide free divers and spear fishers the ultimate in comfort and reliability.

Comfortable foot pocket and powerful blade provide efficient thrust and unparalleled underwater maneuverability.  

Although more expensive, rubber is our chosen material for Fathom Blue's foot pocket.  It might seem a bit old fashioned but at the end of the day, it is all about performance.  Our custom designed rubber foot pocket offers an unmatched combination of flexibility and durability to produce a spring-like effect when finning, yet its base (sole) is rigid and efficient.  

The flexible fin slants downward from the toe at a 22° angle to maximize power and efficiency.

Fathom Blue comes to you in a sturdy, attractive black gear bag with handles and shoulder strap that’s perfect for travel or storage.
