The SIDI Crossfire 3 MX Boots have been completely redesigned, with only the acclaimed SIDI cam lock buckles and straps carrying over from the Crossfire 2 Boots. The new 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 riders 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 Boots are possibly the most durable motocross boots on the market.
