RK3 Military Rubber Fin with Adjustable Stainless Steel Spring Straps

Nice fins, great thrust and comfortable under water. Built to last.

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

フィンのストラップを変えようと思ったら片方のネジが死んでてピンが抜けない事態。

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

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.
