Aequilibrium Top GTX is the lightweight, high-tech high-performance boot for fast mountaineering on mixed terrain and for use at medium altitude

State of the art technology, it is the perfect synthesis between lightweight, comfort and durability. Exceptional walkability thanks to the innovative construction of the Double Heel™: the very pronounced double rear block geometry increases the braking effect on the descent and allows a smoother rolling, reducing muscle fatigue. Durability and lightweight coexist in harmony thanks to the new outsole / midsole package with external Rubber Guard™ shell construction and internal foam material for accentuated cushioning and lightweight derived from less use of rubber layers. The shape is Ergonomic: enveloping and precise with TPU shells integrated in the toe and heel to reinforce the uppers. The 3D Flex System Evo™ directional joint with shaped malleolus and external fold lines allows better control of the support and perfect mobility of the ankle. The external water-repellent elastic Cordura® gaiter allows maximum water repellency while the internal GORE-TEX Performance Comfort membrane allows sweat to escape but keeps water out. The lacing integrates the precise and fast BOA® Fit System. The midsole is semi-cramponable for use with crampons in case of ice or snow, sole with Vibram® SpringLug Tech tread with Impact Brake System lugs for greater adaptability to hard rock surfaces. Mountaineering in perfect harmony.

Technologies

Resole Me

Resole, renew, reuse. Compression Eva midsole with recycled materials from the production process. Resoling Platform: allows easy resoling without damaging the EVA midsole in the process.

3D Flex System

An innovative multidirectional hinge on the upper allows the ankle to make the most of its natural characteristics without losing stability. Enhanced foot control on difficult terrain. Larger sole surface in contact with the ground. Enhanced stability. Even better fit. More secure heel

Impact Brake System

The innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill. Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.

GORE-TEX® Extended Comfort

Waterproof and breathable membrane, perfect even for fast-paced pursuits.

VIBRAM®

Vibram® soles, thanks to the combination of hyper-functional design and exclusive rubber compounds, ensure best performances in terms of comfort and lasting quality.

BOA® Fit System

Dial in to fast, effortless, precision fit. Agility and speed: The BOA® Fit System enables faster, more powerful directional changes through a seamless connection between equipment and body. Power and precision: Power without compromising precision, the BOA® Fit System delivers more explosive action and unparalleled accuracy.

Aequilibrium

Equilibirum - a state that makes it possible to control the position and movement of the body in space. It stays also for harmonic: the synthesis between opposite and contrary forces. Aequilibrium Series: the perfect balance between comfort and technicality, lightweight and durability for the modern mountaineering.
