Discover TLS

To reduce weight, even more, we are using full EVA outsoles on selected models. While keeping weight low, the EVA also provides great impact absorption and thermal insulation.

Selected EVA outsoles are reinforced with strategically placed rubber reinforcements for added resistance, traction, and durability.

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.

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.
