Yes, Truefin has a limited lifetime warranty on each fin (excluding heel straps). In addition, the spines have a lifetime guarantee against breakage. Truefin has never broken a production injection molded glass filled nylon spine, and would like to obtain any spine that breaks for critical examination. If a user ever breaks a spine simply contact Truefin for a free replacement. Note that when a spine is stressed or pried against an immovable object such as between large rocks for example, the vertebrae draft angle may cause the effected vertebra (typically link 50000 or 60000) to laterally slide out of position. If this event occurs the spine may be reassembled and no damage occurs. Please refer to thewww.TruefinTechnical.comfor spine load testing information.

Total weight for one pair including spines and excluding heel strap - 6.2 pounds. Flat dimensions (size Large) - 23.4in long x 10.4in wide. Spines may be removed from the fin and packaged separately, while the pair of fins may be folded lengthwise. When the fins are folded, the pair of fins together occupies a volume of 6” x 10” x 18”.

Yes. Although Blue spines are great for all kicking styles, Truefin may be optimized for frog kicking without effecting flutter kicks after installing Green spines. A combination of a Blue spine used at the big toe and a Green spine used at the little toe improves canted frog kick performance (which creates a right and left fin). If a user wants the easiest kicking possible then Yellow spines are preferred, however the user will need to kick at a higher frequency for a given speed if Yellow spines are utilized.  The user may also mix and match Blue, Green, or Yellow spines.
