The Apeks RK3 HD is the latest model in the RK3 range, made from higher-density thermoplastic rubber than the standard RK3. This makes the fin stiffer and negatively buoyant, making it ideal for wetsuit diving.

Sizing Information
The Apeks RK3 HD does not have a specific shoe size range, as sizing depends on the type of footwear used and the diving environment.

For example, a diver wearing wetsuit boots may require a different fin size from someone wearing rigid drysuit boots, even if both wear the same shoe size.

We recommend choosing your fin size based on your diving boots and trying it on with the footwear you intend to use.
