Flex Rating

TriForce Frame

To reimagine our performance, we had to reinvent our construction. Enter the 3Force Frame. This approach surrounds a lightweight, rigid frame with softer plastic in the cuff and shell - delivering powerful energy transmission without compromising comfort. The result is a boot that’s lighter, stronger, and more responsive in every turn.

3D Custom Cork Liner

3D Custom Cork Liner is equipped with the natural cork material which covers the heel surface, an essential part in providing lateral transmission. This responsive material also provides thermal insulation, keeping your feet always warm and dry. Lastly, it's easily customizable to reach the best fit and precision.

Fitting Your Boots

 – To properly assess the fit of any boot you must lace or buckle it completely. The boot will feel small until you do this because your toes will be pushed to the front until laced or buckled. Also, keep in mind all boot liners stretch out and get bigger. 

– First, lace or buckle the boot loosely. Next, flex into the boot to drive your heel into the heel pocket. Doing this makes room for your toes. Lastly, finish lacing or buckling the boot in a flexed position.

– Be sure to wear the boots for at least 10 minutes fully laced or buckled before making a determination. Remember these boots are not made for walking, keep your knees slightly bent and flexed forward into riding position. When doing this your heels should be pushed into the back of the boot and your toes should be comfortable. 

– You should wear the thinnest sock you are comfortable with. Blood flow is the number one thing that keeps your feet warm. Adding more material around your feet with thicker socks increases the chances of reducing blood flow.

– To help your foot sit properly in your boot, you may consider an aftermarket footbed like Superfeet® or Sidas®. A footbed with arch support, not just cushion, helps align your foot in the shell and alleviates pressure points. Footbeds should be sized to your arch height and length, not your shoe size. 

– Spend some time choosing your boots, they are the most important piece of your gear!
