The MB project objective has been to renovate our medium-high range of fins featuring carbon fiber blades.
At C4, the 200 series fins are considered the most technical while we think these MB fins are our best interpretation of the concept of traditional carbon fiber fins.
Foot pocket 250
For the development of these fins we started from the design of the foot pocket. MB Fins feature the new 250 foot pocket, a direct derivation of the previous 300 model.
Thanks to the use of a TPE 75 ShA polymer overmolded on a rigid sole, the 250 foot pocket transmits energy from the foot to the blade in the best possible way, resulting in highly efficient fins.
The design of the geometries has allowed to use minimum thicknesses resulting in a reduction of the weight of the 250 footpocket in size 41/42 to just 250gr.
Performance
The reduced mass (weight) of the 250 footpocket minimises the energy required for movement, thus allowing the user to save considerable energy and consequently reduce muscle fatigue.
The connection between the foot pocket and the blade, thanks to the internal sole, is rigid and solid, and transmits the force to the blades efficiently.
The assembly of the blade on the footpocket without side horns, already created by C4 in 2006, allows an elastic bending of the blade along its entire length.
