CAS (Custom Adaptive Shape) Shell

This type of shell mimics the natural shape of your foot which makes for a better initial fit. The special dimple shapes create less surface tension and help maintain heat when molding the boot. The result is a longer lasting shell with higher quality performance.

CAS (Custom Adaptive Shape) Liner 

The inside of the liner is shaped to match the anatomical shape of your foot, while the outside of the liner is shaped to fit the shell. These liners are durably designed and built to be less suseptible to being packed out, resulting in a longer lasting fit. 

Celliant® Liner

Powered by 13 thermoactive minerals that convert heat into infrared energy. The result is improved warmth, performance and temperature regulation. 

T-Ride Walk System

Fully-integrated into the boot construction that connects the cuff-to-shell in a perfect balance of downhill performance and uphill hiking.

Quick Instep

A softer plastic is used where your instep is located when in the boot. It allows the boot to open easier, be easier to put on, take off and be comfortable while you’re wearing it.

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!
