Overview
A denser thermoplastic elastomer blade is the working part of this fin, stiffer and slightly heavier than the standard RK3. A stainless steel spring strap makes it quick to put on and take off, and the foot pocket is large for drysuits.
Stiffness and negative buoyancy suit divers who want a fin that resists floating, with a pocket roomy enough for drysuit boots. The listing leaves out blade length and weight, and sizing relies on the maker's chart.
Who it's for
Wetsuit and drysuit divers who want extra stiffness and a roomy pocket get a durable fin with a spring strap. Divers who prefer a soft, light travel fin, or who need exact sizing by shoe size, should check Apeks sizing first.
Pros and cons
- Denser TPE adds stiffness
- Large pocket for drysuit boots
- Spring strap eases on and off
- Multiple color options
- No shoe sizes given
- Blade length is not listed
- Heavier than the standard version
Performance notes
A denser material makes the blade stiffer, which transfers more of each kick to the water, and it also adds weight so the fin trims lower. The pocket size depends on the footwear you use, which is why Apeks leaves out standard shoe sizes.

What size should I choose for the Apeks RK3 HD?
Sizes run from S to XL. Apeks leaves out regular shoe sizes because the footwear, such as neoprene boots or drysuit rock boots, decides how much room you need.

It uses a higher density material, which makes it stiffer and slightly heavier.
Does it have a spring strap?
Yes. The description lists an easy-on, easy-off stainless steel spring strap.
