La Sportiva men's high alpine boots Aequilibrium ST GTX black/yellow 31A999100 (ZFMS072999100)

Aequilibrium ST GTX is a technical, lightweight shoe ideal for via ferratas, trekking, and high-altitude expeditions on varied terrain. These exceptionally durable and functional shoes provide comfort and safety. Thanks to compatibility with semi-automatic crampons, this model is suitable for those who prefer more demanding climbs and need equipment that ensures maximum grip when moving on ice.

The shoes feature an ergonomic, precise, and snug fit with TPU shells integrated into the toes and heel to reinforce the upper. Maximum comfort is guaranteed by a tongue with a soft snow guard on the collar.

The upper made of synthetic fabric HoneyComb Guard™ ensures optimal breathability and durability of the Aequilibrium ST GTX model. This prevents your foot from overheating. The fabric is also resistant to mechanical damage, which increases the lifespan of the equipment and your safety on the trail. 

Waterproofness is another feature that makes La Sportiva Aequilibrium ST GTX shoes reliable in mountain conditions. Thanks to the GORE-TEX® Performance Comfort membrane, the foot is protected from moisture while the shoes maintain their breathability.

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.
Double Heel™
Two-part heel construction in trekking shoes. The part located under the heel ensures less strain on the leg muscles during long hikes. The part located closer to the toes ensures better control when descending.
3D Flex System Evo™
Technology used in the construction of the shoe's upper to protect the ankle joint from injury.
GORE-TEX® Performance Comfort
A versatile technology used in most trekking boots. It provides the boots with resistance to very adverse weather conditions. It is characterised by being waterproof, windproof and breathable.
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.

    How to measure the length of your foot - instructions in 4 steps

    1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

    2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

    3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

    4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
