Advice : Use the foot sizer from SIDAS to help you find the right size
The Trango Tech Leather GTX is a men's mountaineering boot from the brand La Sportiva. It is the leather version of the Trango Tech GTX: it will be more robust and protective.
It incorporates the technical features of the Trango family while being suitable for multi-day backpacking with a loaded rucksack. It is ideal for alpine hiking, technical approaches, or professional use by mountain guides and rescuers.
This boot offers excellent stability and effective protection at the front of the shoe. On the sole, Vibram® technology combined with a shock-absorbing polyurethane midsole guarantees greater durability and impeccable grip. Its upper is made of nubuck with microfiber reinforcements, resulting in a comfortable, insulating, and lightweight boot.
You will also benefit from good support, smooth roll-off, and a relatively light weight. Its GORE-TEX® membrane ensures the boot is waterproof and breathable, keeping your feet dry all day long. As for the 3D Flex System junction at the ankle, it allows for a very comfortable range of ankle movement while maintaining effective support.
The product runs small: our team suggests choosing one size above your usual size.
