The upper material of the Forma Ice Pro boots is made of microfiber. These boots feature a personalized double-density rubber sole and injected plastic sliders, providing excellent grip on your motorcycle. To ensure full protection, the boots are equipped with the F.C.S. (Flex Control System). This system gives additional ankle support, allowing for excellent front-to-back movement while preventing lateral twisting. Sideways movement is completely restricted, helping to avoid possible ankle injuries during abrupt motions. The side ventilation openings in the toe sliders allow air circulation. Air enters through these side openings and exits through the ventilated heel cap. For easy donning and removal, the Ice Pro boots come with a Velcro and zipper system. Additionally, a ratchet closure at the back allows for precise calf width adjustments. The inner lining is made from Air-Mesh, creating a comfortable, breathable experience. The antibacterial and replaceable footbed further enhances comfort and hygiene.
