Response Rating – 5 (1 Soft - 10 Stiff)

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

Cloud 6 Liner [Heat Moldable] – Nitro's Cloud 6 liner is ultra comfortable and highly flexible. Molded from lightweight Thermacell material, this liner provides all-over cushioning for maximum impact absorption. Featuring Nitro's internal lacing system and molded Latex heel pads for infinite heel fit and Nitro's flex toe construction for a highly customized feel.

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.

Lo-Heel Frame – More flex and a precise shape.

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.

Dual Density Footbed – For zonal support and dampening.

EVA Outsole – To reduce weight even more, Nitro is using full EVA outsoles on selected models. Despite the low weight of the EVA sole, it provides high damping and thermal insulation.

Rubber Impact Panels – Selected EVA outsoles are reinforced with strategically placed rubber reinforcements for added resistance.
