Apeks RK3 Tech Diving Fins

Simply the BEST Tech Diving Fins

The Apeks RK3 Fin is designed in collaboration with the US military and is renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an oversized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing.

The RK3 is available in sizes: Small, Medium, Large and Super.

Apeks didn’t give the RK3 fins a shoe size range as this can be very misleading with the fin.

The environment in which an RK3 is used will tend to dictate the size of fin 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.
