K2 FL3X Diverge LT Alpine Touring Ski Boots 2023

When you think touring boots, you probably imagine something sleek and aero, spangled in carbon fiber and secured with nylon cable and Dyneema. But this? The K2 FL3X Diverge LT Alpine Touring Ski Boots are a freetouring dream. With design notes taken from the freestyle world, these three piece, smooth flexing kicks prove that you can get up the hill without being stuffy about the way back down. They’ve got the low weight, tech fittings, and walk mode you need out of a touring boot, plus the stiff feel, bomber heel hold, and linear flex you need to send backcountry booters and smash pillow lines once you’ve ripped off your skins.

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

Liner

Intuition Pro Tour Tongue Liner
–
With a Tour Flex Notch, removable external J-bars, and a lacing system, the Intuition Pro Tour Tongue makes walking a blister0free experience in an enveloping snug fit, while giving you the performance you need to send it on the downhill.

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

Diverge Tour Shell
–
The Diverge Tour Shell offers a smooth stride and articulated purchase in any situation. Walk further and more comfortably than ever before. Featuring a higher back cuff and lightweight Grilamid plastic, this construction will take you anywhere.

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.

Ski/Walk Mode

Walk Mode
–
Flip the lever up to ascend with ease. And when it’s time to send it, flip the lever down, lock the cuff in place, and push into the fluid, progressive flex you’ve come to expect from Full Tilt. Works great for aprés bar sessions too.

Buckles

Tour Hook
–
Keep your buckles in place without impinging upon the full cuff rotation.

45 Degree Heel Lock
–
Keep heels where they belong. Placing the middle buckle at an optimal 45 degree angle creates a solid lock for the heel to stay put when pressuring the tips and tails of the skis.

Power Strap

Velcro Strap

Bootboard & Footbed

Shock Absorber Boot Board
–
Soft rubber in the sole of the shell absorbs vibrations, impact, and shock for a smooth ride.

Sole

GripWalk ISO 23223 Outsoles

Removable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking.

Additional Features

Tech Fittings
