High-performance boot with ideal VACUUM technology for a perfect fit. Excellent addition in the calf area: the new VACU-PLAST spoiler. A boot suitable for walking thanks to ultramodern Hybrid technology, the Ski/Walk Mode. This extremely precise adjustment to each individual foot brings considerable benefits: a perfect fit around the whole foot – including the heel. This is why it is so aggressive, responds quickly and goes into turns so effectively. Technology worthy of world champions!
