Apeks RK3 Diving Fin - Great For Drysuit Divers The Apeks RK3 Diving Fins are vented, "jet fin" styled fin with an oversized foot pocket that makes them ideal for drysuit diving. The RK3 fins also feature a stainless steel spring strap to make it easy to get them on and off. The Apeks RK3 is a rugged fin made with thermoplastic rubber and is available in four sizes: Small, Medium, Large and Super. The RK3 spring straps are easy to replace and are available here Apeks specifically avoided giving the RK3 fin a shoe size range as this can be very misleading! Rock boots and drysuit boots vary greatly in their physical size and also the amount of thermal socks a diver wears. 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.
