300: THE PROJECT

1/3 tradition, 1/3 innovation, 1/3 di design, add (sea) salt to taste. This is the recipe of our 300 foot pockets. 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: FORCE CONTROL

The foot on blade thrust position is about 30mm back, it lies between toes and the metatarsus. Longerons are short where toes are and continue under the foot pocket towards the heel. They are an uninterrupted line of energy distribution between foot and blade. Longerons progressively transfer energy to the blade, allowing exceptional bending curves. Blades continue for over 20mm inside the 300 foot pocket towards the heel. Special blades must be produced to perfectly fit the 300 foot pockets.


300: A UNIQUE ANATOMICAL SHAPE

The 300 unique footwear anatomy is obtained by superimposing the shapes of our right and lef anatomical foot pockets, the Mustang, with their 3°angle. Angle also maintained in the 300 foot pockets. The 300 modular foot pocket anatomic shape is designed to tightly fit to the feet so that energy is transmitted on all foot areas. Thanks to this anatomical design, the energy dispersion caused by unwished gaps between foot and footpockets, is the least possible. Force is naturally applied with the least effort. Fitting and comfort are extremely high thanks to the innovative material used to manufacture the 300 foot pocket shoes which also allows for a 7 time higher resistance compared to other traditional materials.
