The X-Helium Michelin® motocross and enduro boots feature a Michelin® MX Hybrid sole. Maximum levels of protection are guaranteed by the polyurethane shin guard, which is particularly extensive and impact-resistant, as well as by the polyurethane lever guard that covers the toe almost completely. The Michelin® Hybrid MX sole boasts a specific design that offers maximum grip, traction and stability. The special compound with which it is made makes it highly resistant to abrasion and tears. The microfiber upper features a minimal shape that adheres to the leg, and has four interchangeable and adjustable aluminum levers, for extremely easy and functional fastening. The breathable Air Tech lining ensures maximum comfort even during the warmest season, keeping the foot area dry and ventilated. Maximum riding comfort and movements are ensured by the removable anatomical insole and by the padding in polyurethane foam, a material able to adapt to the boot wearer’s foot shape, retaining it even after intense use owing to its particular “memory effect”.
