Response Rating – 8 (1 Soft - 10 Stiff)

Flex Link Design – A flexible panel between upper and lower shell ensures an even flexing, responsive boot without bulk.

Cloud 9 Liner [Heat Moldable] – Nitro's flagship liner combines ultra lightweight Thermacell material with comfort and fit. Their signature latex heel pads provide lifetime heel fit, while the clutch tongue makes boot entry and exit easier. The Cloud 9 liner features an additional power strap for a snug fit on top and a triple density footbed with air bag for maximum cushioning and comfort. Heat moldable.

ILS Liner Lacing – Nitro's 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. Nitro's engineered laces provide less friction and a Dyneema® core for added strength.

TLS 5 Twin Lacing System – Easy lace engagement and release combined with the low abrasion of Dyneema® laces are the key factors of this highly reliable zonal lacing system. At the same time, the TLS 5 features compact size and low weight while maintaining the reliability proven by tens of thousands of days on the mountain. Although rarely needed, servicing and replacement parts (including the lace) are easier than with any other system on the market. Even using a standard shoe lace if you're in a pinch is an option only available on Nitro's TLS boots.

RE/LACE Liner Locker – Another innovation from your friendly developers at Nitro: The new RE/LACE Liner Locker provides easy adjustability of your inner boot lacing when your boot shell is already tightened (tied), by just pulling up on the lace handle. This allows you to (re)tighten your liner and foothold throughout the day (on and off the chairlift) without having to untie you boot.

Bail Out System – Designed to make unlacing the TLS system even easier. This pull tab placed in the middle of the TLS lacing system on the outside of the boot allows for effortless unlacing and record breaking speeds for taking your boots off.

Molded TLS Lace Handles – Even more comfortable with a perfect and smooth fit to you hand.

Ortholite® Dual Density Footbed – Top notch control and cushioning.

D30® Dampening – D3O® is a smart material that moves slowly and increases comfort when in a normal state, but when shock or impact is increased the materials lock together to absorb and disperse energy created upon impact, before instantly returning to its flexible state. What this means is that the material increases overall comfort of the liner by absorbing impact from deep landings or choppy snow conditions – allowing you to go faster and deeper all day!

Air Dampening – Nitro's trusted AIR suspension technology is now featured on even more models. The best shock absorbing technology on the planet sucks up hard landings and keeps your heels from getting bruised. This noticeable difference in ride and comfort does not compromise response or control

Therminator Shield – This thermal layer between sole and liner will reflect your body heat and keep your feet warm all day.

Armored Spine – Nitro uses an anatomically shaped and 3D molded heel reinforcement to provide even boot flex and long-lasting heel fit.
