La Sportiva

Aequilibrium ST GTX is the lightweight, technical boot ideal for via ferrata, trekking and crossings in glaciers and on mixed terrain. Maximum comfort is guaranteed thanks to the tongue with the soft snow guard on the collar. Exceptional walkability thanks to the innovative construction of the Double Heel™ heel: the very pronounced double-wedge rear geometry increases the braking effect downhill 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 enhanced 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 upper. The 3D Flex System Evo™ directional joint with shaped malleolus and abrasion resistant protection, allows better control of the support and perfect mobility of the ankle. The toe protection at the toe lacing protects against chafing. The midsole is semi-cramponable, the sole adopts a Vibram® SpringLug Tech tread with Impact Brake System lugs for greater adaptability to hard rock surfaces. Mountaineering in perfect harmony.
