C4 Surfer Fins
Complete set of modular fins that include plastic blades, foot pockets and mounting kits
These foot pockets are the lightest on the market. Very hydrodynamic designed to give continuity and fluidity to form.
300 feature an elegantly balanced shape in a few hundreds grams. The technology behind this products is mainly focused on volume reduction. Volume is in fact the primary cause of foot pockets “weight” in water, which then requires a bigger effort when kicking water. So, the higher volume of water, the bigger the effort. Reducing volume, weight is reduced, and therefore reducing the ‘sinking’ effect. A 300 foot pocket size 40-41 only weighs 315gr. Compared to 600-750 gr. of standard shoes on the market.
300 fins elegant shape could have easily been designed by lines of water flowing on your feet without interruptions and only ongoing smooth lines. Hydrodynamics is key to reduce divers’ fatigue and these footpockets shiny look combines beauty and performance.
In the past, to dive at very high depths, fin blades, longerons and foot soles had to be extremely stiff. This was the only way to achieve performing fins. Nowadays, blades are soft and performing, therefore modifying the divers’ athletic movement as less effort is required. This is diving, not skiing and not even climbing, where strength is key. Modern blades can bend under few hundreds grams. Stiff foot soles and footpockets are not necessary any longer as they even limit divers’ performance. C4 goal has always been to create products which allow for a fluid and constant movement in water. As a matter of fact, footpockets must serve divers helping them to freely move their feet. This is why C4 300 foot pockets’ calibrated stiffness, in combination with modern soft and angled blades, offer an amazing swimming experience. This is what modern divers require, nothing more than that: a really efficient performance.
These pockets currently can only be mounted on compatible blades.
FOOT POCKET WEIGHT: 316 gr. in size 40/41
Foot pocket sizing is more of an art than a size chart would lead you to believe. Our recommendations below are based on wearing a 2mm sock and years of experience fitting customers with different foot shapes. Your personal preferences, how wide or narrow your is and whether or not you use different sized socks will determine how a pocket feels on your individual foot and is different for everyone. The foot pocket should fit SNUGLY but NOT TIGHT. Any pressure points or loss of circulation needs to be avoided. They should also not be loose, fitting so there is no movement between your pocket and foot causing inefficient energy transfer, bad technique and foot cramping.
