The METRIX system was born to satisfy discerning skiers during tests or premium rentals. This system can be mounted on all flat skis available on the market. Every force exerted by the skier is perfectly transmitted to the skis, thereby offering ski quality similar to skis that are sold on the market. Never before has the coupling strength between boot and ski reached these levels. The METRIX system is equipped with a reinforced Full Action toe piece and SPX heel. It can be adjusted to fit boots measuring 260 mm to 360 mm in length. It's compatible with all ISO 5355 A and GripWalk® ISO 23223 A adult boot soles.
