RK3 Fin

Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes: Medium, Large and Super.


We didn't give the RK3 fin a shoe size range as this can be very misleading.


The environment that an RK3 is used in will tend to dictate the size of fin that you need, for example do you dive in a warm environment wearing wetsuit boots, or are you walking across pebbled beaches and wearing a drysuit and rigid dry boots? Both forms of footwear may be a size 9, but will take up different amounts of space in the fin foot pocket.


Therefore, we recommend that you visit your local dive store and try the fins on with your own footwear, just to ensure that you're getting the right fit for your style of diving.


The vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex.

The blade material designed to hold up in the toughest environments, temperatures and abuse.

Two large grommet holes designed to fit most karabiners for easy storage of the fins while accessing the dive site.

Spring straps as standard.

Custom designed buckle holds spring straps in optimum position.

Simple push pin design allows simple replacement of springs if necessary.
