If you have to walk for a distance you can do so easily in your Omega Navigators flipped up. Gimmick, hinges, or whatever you want to say your opinion is not the only truth. Force fins rock if you can find some, and they fit your foot well. In my case they just don't fit as comfortably as my Navigators, which I've tested side by side even one of each at a time with my force fins. Larger surface area, slightly more effort, slightly more output. If you won't buy force fins now you may later. If you start with Navigators now you might not need anything else. And no, I'm not affiliated in any way with Omega. I just like offering a different opinion from someone who has a pair of BOTH.
