La Sportiva men's high alpine boots G-Tech black 31F999100 (31F999100)

Advantages

Compatible with automatic crampons
The boot features a moulded insert above the heel. This allows the use of automatic crampons and provides safety by making it easier to navigate icy sections in difficult terrain.
Adhesive
To keep you safe as you move through variable and challenging terrain, a special compound was used to create the outsole and a suitable tread was used. This allows you to step with confidence.
Partial lagging
The partial lace-up shoe has protective inserts in the toe and heel area. In the case of sudden changes of direction, when the heel leans in different ways towards the ground, the insert protects against damage, just like the one used on the front of the shoe. This makes this model ideal for difficult terrain.
Compatible with cage crampons
If you are a lover of winter mountain excursions but have no need to buy specialised equipment, this boot model will be a good choice. Its design ensures compatibility with basket crampons, which will keep you safe while winter trekking in the mountains.
Durable material
When trekking, especially in rocky terrain, trekking boots are prone to damage. Durable and strong fabrics have been used for this model to minimise the risk of damage to the boots and extend their life.
Waterproof
The boots, are made from materials and using technologies that guarantee good waterproofing, providing protection from harsh weather conditions. This will ensure that you cover more miles on the trail without worrying about your boots getting wet in the unexpected rain.
Compatible with semi-automatic crampons
If you want to try more demanding winter hiking but don[t want to buy specialised boots and crampons, this model will be suitable. Its design ensures compatibility with semi-automatic crampons.
Impact Brake System
Innovative La Sportiva brand technology applied to the sole of mountain boots for walking shock reduction, traction support and improved ground grip. The unique placement of the tabs ensures maximum impact absorption.
3D Flex System
Technology patented by Italian brand La Sportiva involving a special lacing system between the upper and lower part of the shoe. It ensures a perfect fit to the calf for optimal wearing comfort.
Vibram® Litebase
The sole reduced by 30% of the total weight, by reducing its thickness, all while maintaining quality in terms of grip and durability.
BOA® Fit System
Fitting system, consisting of a strong line, hooks and an adjustable knob. It guarantees a stable and comfortable fit of the product to the shape of the body. The user has the possibility of very precise adjustment.
Vibram® SpringLug Tech
This new technology consists of a rubber coating that offers superior protection and significant scratch resistance, as well as providing excellent grip. The low-density polyurethane content maximises comfort and also ensures that the sole adapts perfectly to uneven terrain.
Vibram® Ice-Tech
Vibram® sole dedicated to both climbing and navigating demanding terrain. It is divided into two spheres to optimise performance and grip. Ice-Tech maintains the performance, quality and durability of classic Vibram® soles.
