Step On®

Nitro Step On® Outsole

Our 100% Step On® compatible rubber outsole will interface perfectly with any Step On® binding on the market for an effortless boot-to-binding engagement. At the same time, it provides a highly effective traction pattern with an abrasion-resistant high-grip rubber compound for durability and a perfect grip. Made from up to 30% of recycled rubber (depending on sole color).
EVA Midsole

EVA Midsole

Used on all boots with rubber outsoles, the EVA midsole reduces the overall weight and provides cushioning and thermal insulation.
Armored Spine

Armored Spine

We are using an anatomically shaped and 3D molded heel reinforcement to provide even boot flex and long-lasting heel fit.
ILS (Internal Lacing System)

ILS (Internal Lacing System)

Our ILS system features a lacing harness firmly connected to the boot shell. This harness snugly wraps around the liner, securing it in the shell and providing precise lacing and fit. Our engineered ILS laces provide less friction and a Dyneema® core for added strength.
Internal Ankle Support

Internal Ankle Support

An anatomically shaped molded plate distributes lace pressure over the instep and top ankle area. Resulting in more comfort and a better, more precise fit.

Liner Tech

Pre-Molded Thermacell

Pre-Molded Thermacell

All Nitro Liners are constructed from Thermacell material, using Nitro specific lasts designed with decades of experience in snowboard boot design. This ensures long lasting fit and comfort without fatigue and boot pack-out.
Heat Moldable

Heat Moldable

Our Thermacell material will adapt to your foot’s shape over time, simply by wearing your boots out riding. If you still feel the need to custom-fit your boots, this can easily be done by heat molding your liners either in shop, using a specific heating system and tools, or even at home.
Patented Re/Lace Liner Locker

Patented Re/Lace Liner Locker

The Re/Lace Liner Locker provides a secure and true liner lace lock every time, while additional allowing for easy adjustability of your inner boot lacing when your boot shell is already tied, by simply pulling up on the lace handle. This allows you to (re)tighten your liner and foothold throughout the day (wherever you may find yourself on the mountain) without having to untie your boots shell lacing system.
DLS

DLS (Direct Lacing System)

Directly connected to the liner, the DLS also features Dyneema® loaded low-friction laces on selected models for ultimate fit and comfort.

Support Frame

To compliment our DLS liner lacing, we are building a reinforced support frame around the liner’s outside. It keeps the liner in shape and provides constant flex and durability.
3D Shaped Tongue

3D Shaped Tongue

The liner tongue is in direct contact with the foot’s most sensible are – the instep. We carefully construct this part of the liner, using multiple pieces and materials, to achieve the best possible combination of comfort and foot enclosure.
3D Heel Construction

3D Heel Construction

Let’s face it: heel lift sucks. This is why we are going through the effort of custom-building a 3D shaped heel pocked into our liners. The result is a positive heel lockdown, but with comfort and ergonomic feel.

Latex Memory Pads

We spend a lot of time on the material composition, design, and positioning of our signature Latex Memory Pads. They are one of our key liner features and will keep your ankle area comfortable and supported all day long.
Flex Toe

Flex Toe

A Nitro industry first over two decades ago, often copied but never equaled: A flexible material is used to build the toe area of our liners, allowing for size variations and a equal fit left and right. And since your toes can move more feely not being crammed into a stiff toe box, they will stay warmer all day long.
