LA SPORTIVA Trango Trk Leather W. GTX Women's Hiking Boots Opal Pacific Blue EU 40

On a crisp alpine morning, a hiker laces up the Trango Trk Leather W. GTX and steps onto a rocky ridge, confident in every footfall. These mid-cut boots combine water-repellent Idro-Perwanger® leather with a GORE-TEX Performance Comfort lining, keeping feet dry through stream crossings and sudden showers. The Vibram® Mulaz outsole with Impact Brake System grips mixed terrain, while the 3D Flex System ankle hinge allows natural movement on steep ascents. A MEMlex EVA midsole with TPU insert cushions each step, and the semi-automatic crampon compatibility extends usability to light mountaineering. Built for women who demand durability and precision, these boots excel on technical trails, backpacking trips, and via ferrata.

Good to know

La Sportiva recommends sizing up half a size for optimal comfort with technical socks. The boot features a 4mm PPE insole with differentiated thickness for arch support. Regular care with a leather conditioner will maintain water repellency and extend the life of the upper. The semi-automatic crampon compatibility means it can be used with C1 crampons for glacier travel or hard snow, making it a true four-season performer.
