The 250 is the latest evolution of the fin footpocket created by C4.
 
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 efficiencient 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.
 
The features that make it unique are:
Very low weight of only 250gr thanks to the TPE 75 ShA material overmoulded on a rigid high modulus TPE insole;
Thin thicknesses that increase comfort and do not cause foot pain;
Comfortable 3° pre-shaped fit;
Blade assembly, without side horns, with a sturdy M6 screw on a hand grip nut;
Hydrodynamic shape and reduced dimensions that make it glide effortlessly in the water.
 
Price per pair.
