Men's La Sportiva Aequilibrium Top GTX high-mountain boots black/yellow 21X999100 (ZFMS075999100)

Aequilibrium Top GTX is a lightweight, technical 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 stability and grip when moving on ice and snow.

Waterproofness is a feature that makes La Sportiva Aequilibrium Top GTX shoes reliable in the mountains. Inside, they are equipped with a GORE-TEX® Performance Comfort membrane, which protects the foot from moisture while allowing efficient air exchange. On the outside, you will find a flexible Cordura® shield that protects against heavy rain and snow.

The Aequilibrium Top GTX model is also characterized by an ergonomic, snug, and precise construction with TPU shells integrated into the toes and heel to reinforce the upper. The upper fabric is resistant to mechanical damage, which increases the durability of the gear and your safety on the trail. Nubuck material, a wedge tongue, and a soft collar ensure maximum wearing comfort.

The BOA™ fit system allows for quick and easy adjustment of the shoes to the foot. This enables the user to optimally tailor them to their needs and feel stable. Stability is also ensured by the specialized Vibram® SpringLug outsole.

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.
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.
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.

    Too wide

    Very nice shoe, but unfortunately not for my narrow foot. The construction of the shoe too wide for me. When twisting the BOA system to the maximum and fastening the Velcro in the upper part of the shoe, the heel and basically the achilles would slide on the heel counter, resulting in chafing. Walking on the flat and especially descending in these shoes is a fairy tale, but on the ascent, I had no joy at all. I usually use Mammut boots, La Sportiva tempted me with the BOA and the "sock". Now I understand all those who claim that Mammut makes narrow boots....
    In summary, the boot itself really well made, sensational BOA system, especially if we have crampons or crampons on the boot, we can still adjust the binding, which is difficult with laces. With a temperature of -10 and a medium merino sock, thermal comfort is maintained. If I had to complain about something, when it comes to winter use of the shoe, due to the shape of the heel, crampon selection is troublesome. The best fit in my opinion, due to the design of the rear of the crampons, was the Black Diamond Serac Clip crampons.
    Interestingly, based on Anita Lipnicka's assumption that anything can happen, I ordered a spare mounting system together with a cable from boafit.com, which I received completely free of charge :-) I will check out the laced version for myself and, if I can adequately immobilise the heel, I will definitely stock up on aequilibrium.

    World Championship

    First day on my feet, heavy winter terrain with collapsing snow, 20 km route, many climbs and sharp descents. No rubbing of the feet, no discomfort, just like in slippers. Highly recommended. And the boa bindings are just like a dream: you can tighten them in photos, release them on straights and climbs, and you can do it all with gloves in a few seconds.

    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.
