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.

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.Ideal
I recommend
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.
