The Sidi Trial Zero 2 motorcycle boots are made from ultra-durable and lightweight Techno Micro Microfibre for superior comfort and outstanding freedom of movement. A trial sole and anatomical and non-deformable rigid heel give fantastic feedback for trial-riding. Embossed rubber on the calf adds grip and reduces heat, and a nylon inner sole and removable arch support pad give superior comfort. An internal ankle pad and PU fixed shin plate give additional impact protection.
