TLS 5 Twin Lacing System – Nitro is leading the pack with the TLS 5 lacing system: Easy lace engagement and release, combined with the low abrasion of Nitro's 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. Even though rarely needed, servicing and replacement of all parts including the lace is 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 Nitro's Bail Out system for an easier entry and exit round off the most developed dual lacing system on the market.

Molded TLS Lace Handles – The TLS handles are even more comfortable with a perfect and smooth fir to your hand.

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 your boot.

Bail Out System – 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.

Anatomical Footbed – Provides shock absorption and comfort.

Rubber Outsole – A highly effective traction pattern, combined with an abrasion resistant high-grip rubber compound provides perfect grip, no matter if you're hiking up the park or down the stairs to the bathroom.

EVA Midsole – Used on all boots with rubber outsoles, the EVA midsole provides cushioning and thermal insulation.
