Im looking at get my first pair of freediving fins. I have just been you using little rubber ones for now. I have tried a pair of mares liberator x open pocket scuba fins before which made one of my ankles quit sore. It felt like I had a problem in my ankle joint. Ive never had that before doing any sport related activities. Will a freediving fin be less tiring then a scuba fin. Im looking at either picasso green starts or cressi gara 3000LD. Can anyone recommend one over the other. Ive just got into the sport so I dont know any one elses who I could have a test. CHEERS.
