The SIDI Crossfire 3 SRS MX Boots have been completely redesigned, with only the acclaimed SIDI cam lock buckles and straps carrying over from the Crossfire 2 SRS 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 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, and serviceable motocross boots on the market - the design uses hardware instead of stitching so virtually every part is replaceable, season after season. 

  • Sole Replacement System (SRS): although hard wearing, the sole is easily replaceable if needed. Just 4 screws allows you to refresh your boots with a brand new Click Sole (sold separately)
  • Replaceable shin plate
  • Micro adjustable and replaceable buckle system
  • Flex-system upper
  • Exclusive and patented flex-system with hyper extension block 
  • Fully adjustable calf area
  • Wider calf upper (+ 3 cm) - adjustable system between the calf, shin and leg upper which allows to widen the circumference of the boot and accommodate even wider calves
  • Replaceable metatarsus inserts
  • Toe area covered with plastic reinforcement
  • Rigid, shock resistant, anatomically shaped heel cup
  • Assembled and replaceable boot leg: stitch-free
  • Nylon inner sole with removable arch support pad
  • A deeper tread Enduro Click Sole is also available (sold separately)


Replacement parts available. SIDI boots are a narrow fit and they recommend going up a size from what you would normally wear.
