The lightest professional boot ever made offers an incredible combination of performance and safety.A boot that raises the bar. Used by professional riders in MX, Hard Enduro and Superenduro, the Crossair offers all the solidity of premium Sidi boots at just 1665 grams (size 43). This makes it much lighter than anything else. An internal fiberglass-reinforced exoskeleton provides the necessary support and safety, while being an incredibly lightweight construction. The sole was developed in collaboration with Vibram® to achieve a new level of grip and flexibility. Nothing compares to the feel of the Crossair.

As melhores botas de enduro que já usei!!!!!
Super confortáveis com um agarre de sola TOP em terra em pedra com lama em ribeiros, simplesmente o melhor que há para quem quer estar muito bem protegido, sentir segurança e conforto esquecendo que tem umas botas de enduro calçadas.
