SIDI Youth Stinger Boots

Small on sizing but big on performance, the SIDI Youth Stinger Boots feature a pivoting ankle support structure that enables fluid fore and aft movement but limits side to side motions. A non-bootie design keeps the boots slim, light and nimble while the cam-lock buckle system is a set it and forget it entry system that makes getting ready to ride a breeze. 


  • Heel Detail: Three extended ribs are featured at the back of the boot to assist the rider in making upshifts with his heel when starting a race. Rigid, shock resistant, anatomically shaped heel for maximum protection. 
  • Non-Bootie Designs: Sidi boots do not incorporate inner booties into their design, and for good reason. Booties make the design larger and cumbersome; add to the boot’s thickness, which interferes with shifting, plus the inner booties retain body heat affecting the rider’s performance and comfort. 
  • Buckles: Sidi’s exclusive cam-lock buckle system is acknowledged as the finest system on the planet. It must be as most of Sidi’s competitors have attempted to copy various aspects of it. The cam-lock buckle system incorporates a strap memory retention system. Adjust the straps once and they will be at the same position for every ride after that! No more readjusting for every ride or mid-day during a ride. 
  • Composite Insole: A cushioned liner is provided that can be removed if the rider desires a more roomy fit. Sidi does not use steel shanks riveted to its insole like most manufactures, details such as this enable Sidi boots to enjoy a multi year service life versus the competitors multi month lifespan as over time, a steel shank can deteriorate, rust and fracture exposing the rider to injury. 
  • Lining: Cambrelle is a lining that, due to its particular polyimide structure, guarantees a rapid drying rate after the boot gets wet or sweaty. This prevents the onset of mold forming which extends the boots lifespan dramatically. The Teflon treated mesh panels in the rear calf area of the boot allow humidity to escape while the boot is in use.

SIDI Youth Stinger Boots 4.5 5 2 2
Great boots for adults with small feet I have a shoe size of 38/6.5 and finding dirt boots that fit has been impossible. Specifically ones with a hinge. Pros -Great quality for the price -Buckles are really nice -Despite only 3 buckles they feel snug -Very flexible and easy to shift Cons -No heal padding or pinch foam -The material used for the liner is very scratchy so if you wear a low cut sock it will be miserable -The shin guard is shorter then most mx boots -The plastic is very thin However addressing these cons would raise the price of the boot and put it out of the range of a kids boot so it's still a great product.

Great MX boot for women with smaller feet looking for an excellent, protective,comfortable boot for an advanced rider. I have searched the Internet and local stores trying to find some MX boots that would protect my calves, ankles, and feet from the rigorous trail riding I do. When a friend bought a pair of Men's SIDI's he raved about the fit and how well they were made. I decided to give them a shot, and super happy I did. Here's why...my feet are tiny and I had a hard time finding a size in women's with other boots, plus the boots lacked proper protection for legs, ankle, and foot. I went with the youth size (I wear a 6.5 in women's) and they fit perfectly, they offer the same protection as the adult boot. I love that the sole of the boot is durable, but I can still feel my foot pegs. The bindings snap in and out for easy boot adjustment, hinged at the ankle, and provides great protection.
