Nitro Vertical TLS+ Boots

Nitro’s latest zonal speed lacing system features a redesigned locking cleat without moving parts. Combined with a specifically developed high-tech Dyneema® lace and new lace loops, it offers the ultimate pro-level fit, lockdown, and foothold. The simplistic power of just pulling up two handles control the top and bottom section of the boot for custom and zonal adjustment.

Vibram Litebase drastically reduces the weight of a rubber sole while maintaining performance. The thickness of the rubber base is reduced to 50% from regular outdoor performance outsoles. Consequently, the weight of the tread is reduced by up to 30%. The result is a professional grade lightweight Vibram sole, with patterns identical to those of a traditional Vibram sole and it has the features of traction and durability.

Vibram XS Trek Evo is the latest evolution of Vibram XS Trek in terms of balancing multi-surface grip and durability, featuring also non-marking properties and excellent adaptability to a wide range of terrains.

Vibram Arctic Grip All Terrain is an all-new technology that improves grip and traction on varied surfaces, while increasing durability. It uses a unique polymer blend and advanced filler system that revolutionizes grip on wet ice surfaces. This evolution of Arctic Grip matches with Vibram XS Trek Evo compound, providing added durability and improved grip on wet and dry surfaces.

Vibram Traction Lug is an innovative design concept that focuses on the key element in traction – the shape of the lug. Thanks to athletes’ know-how and the constant drive by Vibram to enhance grip and traction, Traction Lug revolutionizes your activity outside, increasing traction, adding stability and improving surface area: this means propulsion and braking power without comparison.

Used on all boots with rubber outsoles, the EVA midsole reduces the overall weight and provides cushioning and thermal insulation.

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

We are using an anatomically shaped and 3D molded heel reinforcement to provide even boot flex and long-lasting heel fit.

Perfectly shaped for a secure fit of semi-rigid crampons.

This product is made with Endure®, a material developed and distributed by Gravity Group Srl. Endure® can withstand the most challenging and demanding outdoor conditions. It is long-lasting, even in wet and cold environments preserving its flexible behavior at very low temperatures without cracks. In addition, endure® has a high-tech closed-cell microstructure that allows achieving the highest toughness while keeping the lowest weight. At equal thickness, it is up to 50% lighter than rubber. Conceived as a higher-end replacement for rubber, Endure® prevents all the drawbacks in the use of rubber related to environmental impact. It is entirely made in TPU, which makes it 100% recyclable.

A construction specifically made for making the transition and performance between hike and ride mode easier and more beneficial for the rider (together with the forward lean adjustment and auto power strap). Hike mode offers a softer flex and ride mode is more responsive and rigid flex.

If you are looking for maximum adjustability throughout the day or season, you can use our removable tongue stiffener to change from premium precision to more of a relaxed feel. It comes in two different densities, allowing three response settings. From the steep and deep to the groomers, you can customize your boot feel perfect for your style.  

Nitro´s new gusset construction enhances protection from the elements on top of the foot to keep you dry and warm. The ergonomic diagonal zipper design allows for one-handed operation while also adding to the durability of the boot and its lacing system.

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.

An anatomically shaped molded plate distributes lace pressure over the instep and top ankle area. Resulting in more comfort and a better, more precise fit.
