Our 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.

A flexible panel at the ankle between the upper and lower shell ensures an even flexing, responsive boot without the bulk.

This precision-molded low-friction plastic insert is positioned at the crucial 45° lacing position in the ankle area. It drastically reduces lace friction and makes tying up your TLS system even easier.

Nitro leading the pack with the TLS lacing system: Easy lace engagement and release, combined with the low abrasion of our Dyneema® laces are the key factors of this highly reliable zonal lacing system. At the same time, the TLS features compact size and low weight while maintaining the reliability proven by tens of thousands of days on the mountain.

Even though rarely needed, servicing and replacement of all parts including the lace are easier than with any other system on the market. Even using a standard lace if you‘re in a pinch is an option only available on Nitro‘s TLS boots.

Easy-entry handle storage pockets as well as our Bail Out system for easier entry and exit round off the most developed dual lacing system on the market.

Designed to make unlacing the TLS system even easier. This pull tab that is placed in the middle of the TLS lacing system on the outside of the boot allows for effortless unlacing and recording breaking speeds for taking your boots off.

An anatomically shaped molded plate distributes lace pressure over the instep/ankle area: More comfort and a better, more precise fit.

For those looking for adjustable stiffness throughout the day or season, you can use our removable tongue stiffener to change between premium precision or more of a relaxed feel. From the steep and deep to the groomers, you can customize your boot feel perfect for your style.

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.

Another innovation from our friendly R&D department at Nitro: The 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 (wherever you may find yourself on the mountain) without having to untie your boot.
