## Overview

The Apeks RK3 Military Rubber Fin combines a time-tested all-rubber design with stainless steel spring straps and a vented blade to deliver unmatched durability, comfort, and propulsion. Favored by elite military and public safety divers, this fin excels in tough conditions while offering a compact size perfect for travel.

## Description

The RK3 fin design has been the standard for Military, Special Ops, Coast Guard, and Public Safety Divers for decades. It is a traditional all rubber design. The RK3 blade material is formulated to hold up in the toughest environments, temperatures, and abuse. The short wide blade provides maximum forward thrust while maintaining great maneuverability. The vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke. The fins come standard with stainless steel spring straps.

Review: Aún no las uso pero el material me parece de muy buena calidad.
Review: 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.

*by K***M on 5 August 2024*

Extremely robust, kick up minimal debris, comfortable, slip on and off easy and stay put nicely while diving. Foot well seems wide at first but that's what makes them go on and off easy and you don't notice it while diving. Part of the design. I'm a size 10 with standard width dive boots. No issues with the standard size. Best fins I've owned. Military grade.
