The skis are designed on forces involved during skiing and they are inspired by nature, precisely to swallows. They are also reduce to essential to be lighter and faster. 
The main study is about the energy involved into the ski during a turn. It isn’t equal for both the skis and it isn’t also symmetrical into the same ski. The energy comes from the inside blade of the downstream ski to the outside. It follows a precise trajectory based three elements: pressure, turn radius and ski flexibility. The ski is designed to be more stiffness where necessary. 

The skis materials are an obvious choice to give them flexibility, lightweight and an interesting texturized surface. Every material involved to built them are light, stiff and selected for them matt finish. Carbon forged is a synonymous about technology and it is used thanks to its fast and cheap building process and ready surface after moulding.
Titanium is used because it is water resistant and 45% lighter than stainless steel.
Apricot wood is involved to its resistance. It is a light and com- pact wood used since the ancients to make inlays. It’s color is pale yellow with dark veins with a smooth surface.
