Given that the Trango is designed for more serious mountain use, including some scrambling, via ferrata or climbing, and that La Sportiva market it as a 3-4 season boot, this is a remarkably light boot at just 1,484g a pair.
Using a tough, synthetic upper of Cordura and Lorica, both of which are waterproof, there is also a Gore-Tex lining to further protect your feet from the elements.
A sturdy Vibram rubber rand protects the boot itself, and a no-nonsense, grippy Vibram Mulaz sole uses sticky Supertrek rubber and features a smooth toe section for better rock traction.
A double-density midsole helps to absorb impacts, and the 3D Flex ankle cuffs provides excellent ankle manoeuvrability, despite the cuff rising well above your ankle.
There's no doubt that the Trango was the least flexible of the boots we tested owing to its intended use for scrambling/climbing as well as walking, and this means some breaking in is required; however, in return you get a top quality boot that will last many seasons and take on any serious adventures in the mountains with confidence year-round - indeed, it's even crampon compatible.
