Frequently Asked Questions
Why do military and public safety divers use Apeks RK3 fins?
The RK3 has been standard issue for military, special ops, coast guard, and public safety teams for decades: a rugged thermoplastic rubber fin with a short, wide vented blade that delivers power in tight spaces and holds up to abuse that destroys composite fins. Stainless spring straps are standard, with grommet holes for clipping the fins off when climbing a ladder.
Apeks RK3 vs RK3 HD: what is the difference?
The HD is molded from a higher-density compound, which makes it stiffer and negatively buoyant — Apeks positions it as ideal for wetsuit diving, where sinking fins help keep your legs in trim. The standard RK3 is the softer-flexing original that most drysuit and all-around divers choose. Same blade shape, same spring straps, same near-indestructible build.
What size Apeks RK3 fins should I get?
Apeks deliberately publishes no shoe-size chart for the RK3 — they consider it misleading, because the right size depends on your footwear. The oversized foot pocket comes in Small, Medium, Large, and Super, and is designed to swallow anything from wetsuit boots to rigid drysuit boots. Tell us your shoe size and exactly what boots you dive, and we will put you in the right pocket.
