JOSEPH T I love these straps. I'm not sure exactly what the model of fins you have, but they were the only ones that fit my Cressis. I would try them and return if they don't work out.

SHAUN S My cressi fins have the male post on the fin. The buckle has a hole that attaches to it. That being said these spring straps do not come with the buckle. It uses the existing cressi buckle and snaps into it. If the end your current strap that snaps in looks like the one pictured for the spring strap, then it should work. It seems to be a pretty standing kind of snap buckle. I'm currently using this same spring strap with a pair of scubapro twin jet fins and it is plugged into the scuba pro buckle.

ROMEO C I say call or chat on-line with the staff, they have never let me down with their advice... I have the Cressi-Sub Frogs, the clips were exactly the same (other than the color of the Cressi logo)... I've had my these new spring straps for a few months and absolutely love them, I wish the original straps popped a long time ago... Hope that helps

TIMOTHY M I do not think they will, the straps snap into a female plastic buckle that is on most modern fins. If you do not have the buckle you may need to get the xs scuba universal spring strap which has 3 diferent types of buckles that fit most old style fins

TA-CHIEH H I have a pair of Rondine A, which I assumed is a later model than your Rondine Gara fins. The way you described the mechanism on your fins, I do not think it to be likely that you can use these straps. The spring straps, in the simplest term, is a spring attached with two quick-release buckles. In order for these to work on your fins, you will need to have the matching buckles (female) attached to your fins. The Rondine A has these female buckles attached with a limited rotation angle on the fins themselves. In your case, I don't think your fins come with these buckles. If you are really creative, and are handy with tools, I believe you can get the matching female buckles (Cressi BZ 170015 Fin Buckle Pair), provided your fins have the hard plastic holes that will fit the buckle insertion. Or, you might have better luck using one of those universal version of spring straps (IST Universal clamp stainless steel coil spring fin strap with style), and work your way through it. (Assuming you have metal stud pairs on your fins) Obviously, you could always buy a new pair of fins and go from there... :) For sizing, I have a pair of small/medium fins, so I got the small/medium straps. I would think a medium/large would probably fit your size, but that's just my guess. And keep in mind that the springs will loosen over time, too, as is my case. They work relatively well, though, as I saved a lot of time donning-doffing. Hope this helps.
