Advice : Use the foot sizer from SIDAS to help you find the right size
The Aequilibrium LT GTX Black/Yellow is a men's mountaineering boot from the brand La Sportiva. The Aequilibrium range responds to a new style of mountaineering with technical yet lightweight products for faster progression.
This boot combines performance and lightness. It features a water-repellent nubuck leather upper as well as a waterproof and breathable GORE-TEX® lining. The edges of the boot collar are softened for better comfort during use, while ankle support is still ensured. The sole is rigid and equipped with inserts for semi-automatic crampons.
To facilitate the foot’s roll, the sole unit firstly includes a rocker at the front and also a special Double Heel™ technology at the endpiece/hinge mount. This technology consists of splitting the heel into two parts to firstly optimise walking comfort but also improve braking capabilities on descents. Finally, the whole is completed by a Vibram® grip and an Impact Brake System shock absorption system.
