Review: Top Shelf Dive Fins - 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. 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. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TY5POYY | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #495,620 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #337 in Diving Fins | | Brand | Apeks | | Brand Name | Apeks | | Closure Type | Buckle | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 79 Reviews | | Fit Type | Regular | | Item Dimensions L x W | 10"L x 5"W | | Item Weight | 5 pounds | | Manufacturer | Apeks | | Manufacturer Part Number | 621160-621205 | | Material | Stainless Steel, Rubber | | Material Type | Stainless Steel, Rubber | | Model Number | 621160-621205 | | Number of Items | 1 | | Sport | Scuba Diving | | Sport Type | Scuba Diving | | UPC | 053242305242 707565260992 | | Unit Count | 1 Count | ## Product Details - **Brand:** Apeks - **Color:** Black - **Fit Type:** Regular - **Material:** Stainless Steel, Rubber - **Sport:** Scuba Diving ## Images ![RK3 Military Rubber Fin with Adjustable Stainless Steel Spring Straps - Image 1](https://m.media-amazon.com/images/I/51pVb2Ny0vL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top Shelf Dive Fins *by K***M on August 5, 2024* Extremely robust, kick up minimal debris, comfortable, slip on and off easy and stay put nicely while diving.

Neutrally buoyant, so weight is not an issue. Durable with plenty of power to move you through the water. Great for flutter kicks as well as amazing for frog kicks! ## Frequently Bought Together - Apeks RK3 Military Rubber Fin with Adjustable Stainless Steel Spring Straps - Cressi Supernova Dry, Black/Black - Hollis M1 Frameless Mask --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/17627279-rk3-military-rubber-fin-with-adjustable-stainless-steel-spring-straps](https://www.desertcart.jp/products/17627279-rk3-military-rubber-fin-with-adjustable-stainless-steel-spring-straps) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-28*
