Advice : Use the foot sizer from SIDAS to help you find the right size
The Vertical TLS+ Black are men's splitboard boots from the brand Nitro. Designed for the finest high mountain explorations, these lightweight and comfortable boots showcase the best innovations for top riders.
For this, Nitro had no choice but to equip them with VIBRAM® and its latest advancements to create a more durable, reliable, and comfortable product, notably thanks to the combination of its Vibram® XS Trek and Vibram® Arctic Grip All Terrain components to ensure optimal grip on all terrains, even on ice. They also incorporate Litebase® technology, which significantly reduces weight by about 30% and thickness by about 50% without impacting performance—imagine that result!
As if that weren’t enough to satisfy everyone, the Vertical TLS+ features a high-cushion EVA midsole that is thermally insulated, as well as a Therminator shield that reflects your body heat instead of letting it escape from the boot.
The anatomical reinforcement at the endpiece provides a barely noticeable fit and offers uniform flex for better sensations both uphill and downhill. Moreover, the boot’s Hike N Ride construction greatly facilitates transitions between different modes, so you can fully enjoy extending your outings and bringing back even more memories!

| TLS+ LACING | Nitro leads the way with its TLS lacing system: two independent lacing zones, quickly tightened and secured by a compact and lightweight mechanism, whose reliability has been proven by tens of thousands of days spent in the mountains. Abrasion-resistant Dyneema® laces specially designed for this purpose, easy-to-access storage pockets, and our Bail Out system for effortless adjustment complete the most advanced dual lacing system on the market. |
| VIBRAM® LITEBASE® | Vibram® Litebase® significantly lightens a rubber sole while preserving its performance. The sole thickness is reduced by 50% compared to standard outsoles. Consequently, the sole weight is reduced by up to 30%. The result: a lightweight professional-quality Vibram® sole with the same tread pattern as a traditional Vibram® sole, combining traction and durability. |
| VIBRAM XS TREK EVO | Vibram XS Trek Evo is the latest evolution of the Vibram XS Trek in terms of balancing multi-surface grip and durability, also featuring non-marking properties and excellent adaptability to a wide range of terrains. |
| HIKE N RIDE CONSTRUCTION | A construction specially designed to ease transition and performance between hiking and riding modes, optimising cyclist performance (thanks to forward lean adjustment and an automatic power strap). The hiking mode offers a softer flex, while the riding mode provides a more responsive and stiff flex. |
| ILS | The ILS system features lacing securely fixed to the shoe shell. This system perfectly wraps the liner, firmly locking it into the shell and ensuring precise lacing and fit. The ILS laces, designed to reduce friction, have a Dyneema® core for increased strength. |
