It combines new buckles of an essential and hydrodynamic design, adjustable to all Cressi models, with a brand new adjustable strap made of highly elastic pure latex.
The latex is the most elastic material from nature and has the quality to extend until 8 times its own length without breaking and with complete elastic memory, that is to say, recovering its initial length.
This on the fin’s strap gives us great advantages:
Allows a relationship between comfort of placement and fin’s fixing, over systems with springs, exactly because of its high elastic coefficient (X8 vs. X1.5 of the spring).
It eliminates the messy need of adjustment that traditional buckles have, a process that not always guarantees a perfect heel fixing, especially with non-experienced divers or stress situations during the equipping process.
It allows, maintaining the flapping comfort, a high pressure level over the heel which is essential to obtain a right energy transmission applied to the fin without energy loss because of the “spring effect”. This is certainly its most significant feature because a strap excessively soft, long or without elastic memory reduces drastically the fin’s efficiency.
It’s easily replaceable and essential both conceptually and in its production and assembly.
The natural latex used is of greatest quality without burdens to affect on its features and it guarantees a high resistance to usage, saltwater and sun exposure.
