The QUANTIX SF defines precision climbing in a new way. The innovative Single-Frame technology encloses the foot from below like a hand and thus allows excellent precision with dynamic flex. Product details Optimal for: Climbing Made for: Men Last: FKS Blasting: Microfiber Materials: External material: Multi-layer Lorenzi microfiber upper. Alcantara insert in the area of the big toe. Inside/Midsole: 3/4 length Flexan 1 mm for good edge support. Outsole: 3.5mm Vibram XS Grip 2 sole Technologies and manufacturing processes Active RandingTA -Tension offers the benefits of a dynamic tensioning system without adding extra material under the key toe positions. The TA (Toe-Abductor) Tension System works with the muscles of the foot to improve toe strength while minimizing disruption to the flexor muscles of the foot. PAFThe PAF (Pressure-Absorbing-Fit) system is an innovative system that distributes heel tension while improving fit at the heel. The strong tension band is interrupted behind the heel to reduce pressure on the Achilles tendon. There, it is connected to a softer rubber that acts like a "bridge" and allows for a full fit to the individual heel shape. The holes at the top of the PAF act as indicators to tell you how much tension/support you have. 1-hole for light tension, 2-hole for medium tension, 3-hole for heavy tension. M50 RubberOur softest rubber compound that offers the best conformability to the natural shape of the foot and toe. The conformable material achieves a Shore A hardness value of 50 and is perfect for use in our SRT system, toe caps and strategic positions on the shoe upper. SF-TENSIONThe SF system encloses the foot from below like a hand and holds it firmly in position. The single rubber protection running around the toe area is also a highly effective tensioning system. The advantage of the one-piece rubber is that there are no interruptions and therefore the rubber adapts perfectly to the dynamics of the foot movements.
