C4 Italy have asserted their position as an industry leader when it comes to carbon fibre dive fin technology, and they carried this tradition with the 400 Line. Following on from the slim design of the 300 foot pockets, the 400s are low volume reducing their drag. The more volume, the more drag, therefore more effort, less efficiency and shorter bottom times.

The 400s are also designed to have a tight fit initially so that they mould to the shape of your foot, producing a form-fit with your feet over time. This reduces their volume, preventing water from accumulating within the foot pockets, and means you use less energy kicking. Tighter fins are more efficient because your energy isn't going into compressing heavy, soggy rubber.

Utilising their knowledge of power application through the leg and feet they're built these fins to create load in between the toes and metatarsus. This is where the foot generates force most efficiently.
