KangaROOS Voltera Coil

With the Voltera Coil and the Voltera Ultimate, we present an elegant "Gentlemen's Package" that is handcrafted in our family-run Hummel&Hummel shoe factory in Germany. Volterra is not only a beautiful historical mountain town in Italy but also embodies the softest leather of the highest quality. We have treated the extremely soft leather with a wax that enhances its luxurious appearance. The black leather version has been hand-waxed and then polished and buffed with natural carnauba wax, while the mocha and cognac colors have been treated with a special liquid lacquer and then polished and buffed with natural carnauba wax. Carnauba wax is derived from the leaves of the carnauba palm and is a completely natural wax. This wax comes exclusively from Brazil and is one of the hardest natural waxes in the world. The outsoles of the Coil and Ultimate incorporate the unique cushioning and energy recovery system KangaROOS DYNACOIL, developed by NASA. Upper material: leather Interior material: leather/textile Outsole: Phylon/TPR/DYNACOIL.
