Which bio-fin is right for you?
All open heel and full foot bio-fins are produced with 100% natural rubber. Just as they all share a 20 angle to work wih your bodies natural tendency to bend slightly at the knees in additon to the obvious bend at ankle. Apollo is the only company that chooses to use these standards for the split-fin. These key elements contribute to top marks for high speed, reduced air consumption, and least amount of leg strain. Only the bio-fin can produce these results. Simply put, the bio-fin is built better. Choose the model that works best for you. Bio-fin pro in Black is produced with a 65 hardness (durometer). We consider this the optimum flexibility level. It will provide the least amount of strain on your body, highest speeds, and lowest rate of air consumption This is the best choice for anyone and particularly for those that need to sustain high speeds for a long period. Also an excellent choice for those that have foot, ankle, knee or other leg pain concerns. Bio-fin pro in Metallic Blue, Yellow and NEW White have a hardness level of 66-70. The hardness level is a result of adding color and not specifically to alter feel or performance. The performance of these color options is similar to that of Black. Yellow and White do have a hardness level closer to 70 and out of the water feel just a touch more rigid. Some divers prefer these options because the slight increase in hardness level means they can feel it a little when kicking. Each color does provide a slightly different performance. However, unless you are formally testing it is unlikely that you would notice the difference between Black, Metallic Blue, 0 Yellow or White. In this case it is really just a color thing! Bio-fin pro XT is specifically produced with a hardness of 75. It is a much more rigid fin. The Apollo Bio-fin standards of 100% rubber and 20 angle ensure this fin provides excellent performance, low strain, and reduced air consumption. Some divers feel that the more rigid blade results in a slightly quicker response to direction changes and alternate kicking styles. The XT is an excellent choice for very strong kickers and divers that have developed an automatic wide kick response when encountering current. When using a split fin a small but quicker flutter kick actually uses less effort and tests have shown that it will provide the optimum performance in current. However, it is natural that a diver use a kick that they find works best for them. The more rigid XT blade provides stronger resistance and a more traditional boat paddle fin feel. C-series Fins are the same as bio-fins described above with the added feature of a factory installed Stainles Steel Spring strap. The spring strap automatically adjusts as need, will not break as easily as rubber, and is quicker to take on and off. The strap includes a heavy rubber bumper that acts as a comfort cushion against the heel and provides an oversized finger loop for sliding strap on and off. The C-series option is available on the Bio-fin pro in Black (Pro-C), Yellow (Pro-C), or White (Pro-C) and the XT (XT-C). Bio-fin Uni offers all the features of the pro in a closed heel (full foot pocket design. It is available in your choice of Gray or Blue. In general people choose the full foot for snorkeling or warm water use. however, the UNI has a roomy foot pocket and can also be used with a boot. it is not quite as simple to use a boot as it is with an open heel fin. So... why would you do this? Because the UNI has a closed foot pocket desing. The result of enclosing your entire foot with or without a boot is 100% energy transfer to the blade. This Uni will actually provide a stronger performance than possible with a strap style fin. Plus, the fins are lighter weight and easier to travel with. Full foot pocket fins have a more specific fit. See marine chart for sizing assistance.
