The Trango Tech Leather GTX is a mountaineering boot made from breathable and waterproof leather for alpine hikes: particularly light, comfortable and durable thanks to the nubuck upper. Ideal for technical approaches and work assignments for mountain guides and rescuers. The seams of the shaft with a simple and modern design have been minimised to increase the overall waterproofness. The use of high-quality leather and the protective microfibre inserts on the upper make this boot very durable. The anti-shock midsole made of low-density polyurethane reduces the impact of the ground and allows the shoe to be used for a long time, while the shock-resistant rubber layer on the toe and heel actively protects against impacts from rocks and roots. Like every La Sportiva product, the Trango series features the 3D Flex movement system, which supports ankle mobility and a dynamic stride. The tongue integrated into the upper is made of soft and elasticated material to offer maximum comfort, which is also enhanced by the ergonomic shape and close fit.
