Apeks RK4 Fins Are Back: Compact, Rugged and Ready to Dive
If the Apeks RK4 Fins have been sitting on your wish list, here's your cue: they're back in stock at Adreno in selected sizes and colours. Compact, rugged and built for controlled movement underwater, the RK4 brings a broad technical blade, stainless-steel spring straps and a practical open-heel design to your next dive. Black and white are back on the menu, with orange also part of the range.
What Makes Them Sick
Good fins do more than get you from A to B. The RK4 is about making each movement count, whether you're cruising along a reef or working on more precise finning techniques:
Add in durable rubber construction and integrated stainless-steel buckles designed to reduce snagging, and you've got a practical pair of fins for regular scuba sessions and technical diving setups. The appeal is simple: compact blades, dependable straps and control where it counts.
Your next pair should suit the way you dive. If compact blades, spring straps and precise finning are on your checklist, the RK4 deserves a spot in your gear bag.
Compact. Rugged. Ready For Your Next Dive.
Three Colours, Same RK4
Black, white or orange: the colour changes, the core RK4 design stays the same. Pick the look that suits your kit, then check your size and current availability on the product page.
Black
The classic choice. An understated finish that fits straight into an all-black setup or sits comfortably alongside the rest of your dive gear. Simple, practical and unmistakably Apeks.
White
A clean contrast to the usual black dive kit. The white finish gives this colourway a distinctive look without changing the features that make the RK4 worth a closer look.
Orange
For divers who like a bold splash of colour. Orange brings a bright finish to the same compact RK4 design. Currently unavailable online; head to the product page for restock notifications.
