Product Details
Fit

Last: 102 mm – Relaxed last for wider and higher volume feet and all-day comfort.
Flex

Flex: 90 – A softer flex for freestyle riding or less aggressive skiers.
Liner

Intuition Tongue Liner – The Intuition Tongue Liner's laminates use multi-layered construction in a traditional tongue liner to provide targeted comfort and performance in a familiar way.

J-Bar – An additional J-shaped piece of foam is inserted internally on both sides of the ankle area to dramatically increase ankle hold and keep your feet perfectly in place for precise control.
Shell Materials & Design

Method Shell – The Method Shell adds much needed depth to the FL3X line. Designed for those with a wider foot, the Method shell incorporates a higher volume fit and a 102mm last.

Ribbed Tongue – 100% ribbed tongue enables smoother, more natural linear flex from your shin to your toe. The tongue bends like a flexible straw, never bottoming out while providing smooth rebound. No more shin bang!

Moldable – Utilizing the QuickFit System, all FL3X boots, shells included, can be molded to the exact needs of your foot. Not all feet are the same, and the FL3X line allows for a personalized, 1-to-1 fit experience.
