The Crossfire collection has evolved once again. The SIDI Crossfire 3 SRS boot has been completely redesigned, retaining only the proven SIDI Cam Lock buckles and straps from the Crossfire 2 SRS boot. The inner gaiter has a larger circumference than that of the Crossfire 2, allowing for an even wider range of calf sizes to be accommodated while securely wrapping the rider's lower leg, regardless of the knee protection system used. On the upper inside of the gaiter, there is a heat protection grip panel made of suede for maximum grip. The revamped dual flex ankle protection prevents movements beyond anatomical limits that could lead to injuries, without restricting the flexibility needed for normal shifting and braking. The SIDI Crossfire 3 SRS boot is likely the most durable, maintenance-friendly motocross boot on the market - the design uses replaceable parts instead of stitches, so virtually every part can be replaced season after season. The new ankle pivot system is developed to limit foot/ankle hyperextension strictly. The new footbed features a more contoured and thicker design, allowing the rider’s foot to rest deeper in the sole. The new Dovetail SR anti-slip rubber sole covers the heel area of the sole and can be replaced using hand tools. Toe and heel areas on the Dovetail SR sole are now fixed firmly to the sole. Coated Technomicro base material in all areas, stylish and cool non-bootie design - The calf plate system features an inner dual adjustment that expands to accommodate the largest calf or knee protection system - Nylon insole with an inner heat shield made of grippy material - Removable footbed - Toe area covered with protective plastic - New rigid, shock-resistant, anatomically shaped heel keeps the rider's foot firmly in place and prevents twisting while providing additional protection, it is interchangeable and sleek - All buckles move independently and have only one fixation point (via a screw), enabling easy closure. Buckles can adapt to the rider’s position as they rotate around the attachment screw when the rider changes position on the bike. The lower buckle protection devices prevent opening during an impact. The central strap system can be fully replaced easily and is available in two sizes. The foot area is lined with abrasion-resistant Cambrelle for more comfort. The upper is lined with Teflon mesh, which completely prevents the absorption of water and sweat. These materials prevent water or sweat from settling inside the boot. The boot dries quickly and pre-treatment also prevents mold growth. All add-on parts are replaceable.
