Our most advanced and versatile speed lacing system provides three different lacing zones using two clasps and two handles. One handle allows the boot to cradle your foot and calf while the other handle secures the ankle and heel. Thanks to these separate zones, the boot anchors your heel for a refined fit that enhances energy transmission.
This reinforced panel cradles the back of the boot to maximize durability and enhance response.
Thanks to two separate flex zones at the ankle, this design provides complete control of the boot‘s flex and ensures your heel stays locked in place.
DEELUXE’s Freeride Tongue is a smooth operator. Especially plush, it maximizes comfort and cushioning while also enhancing durability. At home exploring the entire mountain, it loves to lay down turns that are especially smooth. And for a truly custom ride, the Freeride Tongue sports a three-position pocket that can accommodate an optional Flex Booster. This enables you to personalize the flex of your boot and tailor it to be either symmetrical or asymmetrical. Make your mark all over the mountain with DEELUXE’s Freeride Tongue.
Available as an accessory, the Flex Booster strengthens a boot’s tongue, creating a stiffer flex while offering additional support. It can also prolong the life of a boot by restoring or enhancing its flex. Thanks to a progressive design, it provides greater resistance as it bends, optimizing support and protection—especially from harsh landings. As icing on the cake, the Flex Booster enables you to modify a boot’s flex for specific adventures—be that reinforcing the flex of a jib boot to slay kickers or transforming a freestyle boot into a banked slalom hero. You don’t need gym shorts to appreciate this flex.
For enhanced comfort and longer strides when skinning, this system extends the range of motion available at the rear of the boot. It's perfect for splitboarders who demand more—and go further.
Waterproof and breathable, this membrane ensures feet stay warm and dry.
This layer of rubber wraps around the toebox and sides of the boot, maximizing durability by providing protection from rocks and ice.
No matter the adventure, you can depend on the Vibram Eastridge sole. With an emphasis on traction and durability, it excels whether you’re hiking, skinning, or riding. Its proven Vibram ICETREK rubber compound is specifically engineered to endure very low temperatures and provide superior grip on cold and icy surfaces. Special climbing zones in the toe and heel area offer additional traction to make ascents safer and easier. And thanks to lugs with a self-cleaning design, the sole readily sheds snow, dirt, and rocks. Get ready to explore with the Vibram Eastridge sole.
