## Overview

The Apeks RK3 HD Fins in size Small are rugged, high-density thermoplastic rubber fins designed specifically for dry suit diving. Featuring a vented blade for maximized propulsion and an oversized foot pocket to accommodate dry suit boots, these fins deliver powerful thrust and exceptional durability. Developed with US military input, they excel in heavy currents and harsh conditions, making them the go-to choice for professional and serious recreational divers seeking reliable performance and comfort.

## Description

The RK3 HD fin is the latest in the RK3 range. It is made from a higher density material than the standard RK3, which makes the fin stiffer and heavier and is therefore the ideal fin for dry suit diving. The new, heavier compound makes it negatively buoyant and produces a stiffer blade, providing additional power in heavy currents or surf. Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 HD 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

Review: Use size guide several sizes - Pay attention to size that is listed as i ordered the wrong size but the return process is simple and secure ...recommend this product but make sure you order right size... look for size guide.
Review: Travel fins - I didn’t keep these b/c my dive buddy thought the material was too flimsy and might be better suited for snorkeling. I never actually tried then in the water.
