We built the world&&';;s first snowbike-specific boot, the Havoc GTXA(R) BOAA(R), specifically for the extreme conditions of backcountry snowbiking. We integrated the legendary MICHELINA(R) sole which provides unprecedented sole durability and grip. Born from years of research and experience manufacturing the most popular snowmobile boots in the industry, the Havoc blends all the best features of a snowmobile boot and an off road boot into one high performance, snowbike-specific package. The Havoc is also a perfect mountain or crossover boot for the most destructive snowmobilers.
