MAKO Spearguns Competition Freediver Fins in excellent condition!! These are not your traditional plastic blade fins. These bent blades are made of a revolutionary new composition of 10% fiberglass + 90% borealis, thus offering many of the characteristics found in more expensive all fiberglass blades.  The MAKO Competition Freediver foot pockets are made with varying materials to give stiffness only where needed and softer compounds in other areas to make for a high performance foot pocket with all day comfort. NOTE:  Our foot pockets fit a wide variety of bent (angled) blades with varying glue on rail profiles, thus making an upgrade to all fiberglass blades such as the MAKO Spearguns Competition Freediver Fiberglass blades, even more affordable. A message from Dano: “ I guarantee these fins and foot pockets to be the finest fins/foot pockets available.  Before producing these fins, I met with several fin factories around the world.  The factory I chose is the same factory that also makes fins and foot pockets for 2 of the most highly respected freedive gear companies in the world.  It gives me great pleasure to offer such high quality fins.
