    Hello, and greetings from Australia. I was thinking of purchasing your Mantra fins for both free-diving and spearfishing. I then noticed that you have produced a new bi-fin, the Taras, but there isn't any description, specifications, or product knowledge on where the Taras fits in to your range of bi-fins. It does appear to be a dedicated free-dive fin. Would it also be suitable for spearfishing? . . . Could you please give me a detailed comparison with the Mantra fin? Are there any videos or product reviews by Michele Giurgola? . . . the Taras is the most beautiful fin I have seen . . . Extremely cool !!! Kind regards, Garry Webster Sydney Australia +61 412 333 111 Answer:
    Hi Garry, the taras bi-fin was designed for freediving. the most important difference is in the footpocket, that is made with natural rubber This kind of footpcoket are very elastic, so the problem could be the use for long time during spearfishing. So we suggest, in the case, to select a comfortable size for your feet. Best regards

    Hi. Do you have some technical info about these fins? Length, width, softness offers etc. Also is the footpocket made to measure like a monofin? Answer:
    We have an unique blade stiffness available for all weight and about footpocket we have same size of taras monofin. Theyb are the most performing bi-fin available today on the market. Blade is aligned with tibia bone and in this case te effort you need for both kick forward and back is fully balanced and will produce a verry effective thrust. Furthermore the footpocket is latex rubber and it is collaborative with the elasticity of the fin. People who used this fin for the first time increased is PB of about 20% !!!

    salve, oltre alla sarpetta quali sono le diffarenze , sostanziali, con le dynami-tech L? Grazie Answer:
    Salve la differenza sostanziale tra dynamitech e Taras bifins è nella scarpetta. Infatti la scarpetta taras essend in gomma naturale lavora in modo collaborativo con la pala (si deforma e riesce a recuperare la deformazione in modo elastico): in questo modo si ha un sostanziale aumento delle performance della pinna.

    Hello, Cetma Composites team. I am thinking of purchasing your TARAS bi-fins for my first carbon & freediving fins. Could you help me choose the best size? My foot size is 226-227mm without socks. I have tried your PRANA fins with s-wing foot pockets of size 35-36 and it perfectly fit my feet, though my toes were a little bit sticking out of the front holes of the foot pockets. I usually wear shoes like sneakers of size 235mm because I need some space between my toes and shoes. In my case, which foot pocket size is the best, 35-36 or 37-38? Some TARAS users (including national/world record holders) seem to wear their fins with fin socks. If I dive with TARAS wearing fin socks, do I need to choose 37-38? I would be happy if I could get your advice. Thanks! Answer:
    Yes we suggest 37-38

    Hi, I want to know more about the difference between the tight fit and the comfortable fit in the taras bifins. How loose if the comfortable fit? Who do you recommend should choose the tight fit, and who should choose the comfortable fit? Answer:
    In the table reported on the taras page there is a range for each size. For example for size 37-38 length is in a range of 230-235 mm, so if your measure is more close to 230 this is confort fit, you are more close to 230 this is more tight. Some competitors for example which measures is 235-240 choose the same 37-38, in this case this will be very tight. If your measurements are not in the range we can do custom enlarging the footpockets to reach intermediate size between those reported in the table. But please take into account that material is natural rubber so you’ll not receive exactly the measure written because we take into account the rubber elasticity.

    Hello from Canada. I would like to order pair of your TARAS by-fins. Before placing my order I would like to confirm if my measurement and choice of size is right. This is also an issue, because my right foot appears to be some 5mm longer than the left one. The question is, if I can send you two outlines (scan of footprint of my foot) for you to look at, and if you would help me to order the right size. Second question is about socks. I sometimes use 1.5mm neoprene socks in colder water - are your recommended foot pocket size would allow me to wear the socks, or socks are not recommended to use with TARAS by-fins? Answer:
    Hello, all you need to do is choosing from our website the option "customize" and enter all the measurements of your feet as they are ;we all have one foot shorter than the other. With the custom footpocket option we adjsut the standard size in order to fit your size at best. Taras model are designed for competitions, if so we suggest to choose them well tight without socks infact "tight" version is for competition, while "comfortable "you can wear for longer time. Best regards
