## Overview

The Apeks RK3 Military Rubber Fin is a compact, ultra-rugged diving fin engineered in collaboration with the US military.

Its oversized foot pocket accommodates various boot types, making it the trusted choice for military, special ops, and professional divers worldwide.

## Description

Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate dry suit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes of medium, large and super. Apeks didn't give the RK3 fin a shoe size range as this can be very misleading. 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 dry suit 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. Therefore, Apeks recommend that you visit your local dive store and try the fins on with your own footwear, just to ensure that you're getting the right fit for your style of diving.Based on one of the first vented rubber fins sold in North America and popular among military and professional divers. Compact, and ultra-rugged for use in harsh environments. Improved foot pocket with spring straps for ease of use with cold hands or thick gloves. The design has been the standard gear issue fin for military, special ops, coast guard and public safety divers for decades. Short wide blade provides maximum forward thrust while maintaining great maneuverability. Vented blade design reduces resistance on the upstroke and en

Review: Strong good fins - These fins are awesome, they're a little bit on the stiffer side and on the shorter side. This makes them great for traveling as you can just barely fit them into a backpack that can still pass as a personal item on a plane. The heel is very fast and easy to get on because of the spring clip. That being said these are definitely better to wear with booties as opposed to Barefoot. Propulsion and maneuverability are quite good with them as well, I really enjoyed them this far
Review: They would be better if they had Bluetooth - I got these fins to replace my Cressi spits that I had for years and finally started cracking. The Apeks are very nice, Just a tad shorter but wider so I can fit them on my roll on bag. Performance is great. Better than the Cressis and I was just down in mexico with them for a week and was kicking like a madman doing some large wildlife photography. Not only could I keep up with the big fish (well as much as a human can) but they were very comfortable and no sore spots, blisters or anything. I also really like the spring straps and it's easy peasy. And there are little holes where you can take them off and clip them to your BC which is huge when you are exiting the water with a large camera in rough seas.

### ⭐⭐⭐⭐⭐ Great fin. Great fit, easy to Fon and Doff.
*by K***O on April 22, 2025*

Great fin. Great fit, easy to Fon and Doff. I was a previous owner of split-fin. I can feel each kick is a maximized thrust. I get more travel from a kick than the split-fins
