Winter rubber traction. For shifting autumn and winter conditions, ranging from wet city pavements to frosty gravel roads, providing proper unstudded traction can be a challenge. Especially since rubber tends to harden and get stiff as temperature drops. In a collaboration with MICHELIN Technical Soles, Icebug now offers a winter adapted rubber outsole. Developed with the ICE Control Technology, solution formulated to provide superior ground control in snow or ice.
