Article No: 52380-40-254EAN: 8017732592460The legendary Crossfire line has evolved again. The SIDI Crossfire 3 SRS Boots have been completely redesigned with only the acclaimed SIDI cam lock buckles and straps carrying over from the Crossfire 2 SRS Boots. The inner gaiter has a larger circumference than the Crossfire 2 accommodating an even wider range of calf sizes and making for a tight seal around the rider’s lower leg no matter what knee brace system may be used. The upper inside of the gaiter features a suede heat protection-grip panel for maximum grip. The Dual Flex ankle has been redesigned to prevent motion beyond anatomical limits that may cause injury without restricting dexterity for normal shifting and braking. The SIDI Crossfire 3 SRS Boots are possibly the most durable serviceable motocross boots on the market - the design uses hardware instead of stitching so virtually every part is replaceable season after season.New ankle pivot system designed to have a hard limit of foot/ankle hyperextensionNew sole boat features a more cupped and thicker design so the rider’s foot rests deeper into the sole systemNew Dovetail SR anti-skid rubber sole covers the arch area of the sole and is replaceable using hand toolsToe and heel areas on the Dovetail SR sole are now a permanent partLaminated Technomicro base material in all areasSlim cool non-bootie designCalf plate system features an inner double adjustment that expands to fit the largest calf or knee brace systemNylon insoleInner heat shield made of high grip materialRemovable arch supportToe area covered in protective plasticNew rigid shock resistant anatomically shaped heel hold the riders foot firm and thus resists twisting while offering added protectionReplaceable sleek micro adjustable cam lock buckle system with memory retention nylon strapsAll buckles move independently of each other and have just one fixed point (by a screw) which allows easy closure and the buckles can adapt to the rider’s position as they pivot on the mounting screw as the rider changes position on the bikeLower buckle guards help protect against opening due to an impactComplete central strap system can be easily replaced and is available in two sizesLined with anti-abrasion Cambrelle in the foot area for comfort the upper is lined with Teflon mesh which prevents complete absorption of water and sweat.
