VTT SR17 SLEEVE

More lightweight and more performant, the new Sidi VTT boot sole is made of nylon with polyurethane inserts. The shape of the moulded part of the pad has been specially designed for the VTT. It allows a good adhesion, facilitates the dispersion of the sleeve and offers an appropriate stability. The central insert decorated with the Sidi logo functions as an anti-drapant. It is practical and useful, especially for less experienced users. The area of the upper part that is more exposed to wear, especially when walking, can be replaced by visors and also offers the possibility of mounting crampons to improve traction on particularly rough terrain. The SR17 corresponds to a maximum result in terms of rigidity for le pédalage et de flexion pour la marche.

TECNO-3 SYSTEM

Le SYSTÈME TECNO-3 s'adapte sur toute la longueur de la chaussure, adaptant la tige à la forme du pied pour un ajustement personnalisé. SIDI's renowned reliable and replaceable locks are improved by a brand new certified material, SIDI Wire, which does not break, thus allowing quick, easy and intuitive adjustments.
