BUGrip® is the name of Icebug’s grip technology for the most slippery conditions. A BUGrip sole is made of a special rubber compound and has 15-19 integrated steel studs. The design of the studs, together with the properties of the rubber compound, give these studs a dynamic function. The studs work independently from each other and are not completely fixed. When weight is applied the studs push in toward the surface of the sole. How far they are pushed in depends on the pressure exerted by the user and the resistance from the ground. This dynamic function makes the studs adapt to the surface and provide the best possible traction on anything from dry asphalt to pure ice. ICEBUG® Technology Performance Information The purpose of the ICEBUG® technology is to provide traction on slippery surfaces. The manufacturing of outsoles with this technology is a complex process. Since the most important component is rubber – a natural material which performance is not possible to entirely control – there might be cases of premature loss of studs from the outsole. Therefore, outsoles with ICEBUG® technology are designed and manufactured with a surplus of studs. The function of the technology is maintained even if losing 3-4 studs on one outsole. After usage in wet conditions, the head or sides of the studs might get a surface layer of rust. However, the relevant part of the stud for providing traction is the carbide tip, and this will not be affected. Warning: No guarantee against slipping. Products with ICEBUG® technology are not recommended for indoor use.

Water resistant

Water resistant materials are either treated or dense enough to repel water. They are not 100% waterproof, but they do give you protection from foul weather, splashing and slush. The gain is a high level of breathability and the ability to shape better with the foot. To maintain the water resistance of a treatment a material needs to be taken care of properly.
