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. 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. Based on one of the first
vented rubber fins sold in North America and popular among military and
professional divers.
