The Crossfire 3 SRS is undoubtedly Sidi's most creative boot. Sidi uses a new generation material called Technomicro. Technomicro is a composite microfiber material that offers better strength, softer texture and lighter weight. Technomicro is also water resistant, highly resistant to abrasion and is easy to clean and maintain. The Hyper Extension Block is essential for the protection of the rider's ankle and tendons, while the Flex System improves the flexibility of the boot and the adjustment of the leg. Finally, the Adjustable Calf System allows you to widen the opening of the boot through simple and practical adjustments, ensuring a comfortable fit. Also, the leg of the boot is equipped with replaceable internal muffler protection, made of PU (Polyurethane) and equipped with a molded rubber insert suitable to protect the leg from engine heat and wear.
