La Sportiva women's high alpine boots Aequilibrium LT GTX black 21Z999402 (ZMFS073999402)

Aequilibrium LT GTX is a technical, lightweight shoe ideal for trekking, via ferratas, and high-altitude expeditions on varied terrain. These exceptionally functional and durable 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 offers maximum stability and grip when moving on ice and snow.

The shoes feature a snugergonomic and precise design with TPU shells integrated into the toes and heel to reinforce the upper. The upper fabric is resistant to mechanical damage, which increases the equipment's durability and your safety on the trail. Nubuck material, a wedge tongue, and a soft collar ensure maximum wearing comfort. 

Waterproofing is another advantage that makes La Sportiva Aequilibrium LT GTX shoes reliable in the mountains. Thanks to the GORE-TEX® Performance Comfort membrane, the foot is protected from rain and water, while the shoes maintain their breathability.

The lacing system allows for optimal adjustment of the shoes to the foot. This enables the user to perfectly tailor them to their needs and feel stable. Stability is also ensured by the specialized Vibram® SpringLug outsole.

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.

    Champions League!

    I bought the boots for my partner based on previous experience with the brand. If anyone is looking for a no-compromise shoe then the Aequilibrium LT GTX model in both men's and women's editions will meet your expectations. The shoe is armoured but lightweight. It guarantees brilliant grip, cushioning and will prove its worth on any terrain in any season. Definitely everything here is a plus, plus their look - insane! When buying, I would recommend taking a size larger, as the shoes are quite stiff inside and it's worth factoring in plenty of allowance for a thick sock and a swollen foot from walking.

    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.
