The Aequlibrium Top GTX from La Sportiva is a high-performance, high-tech boot for mountain sports on varied terrain that leaves nothing to chance: The double heel construction is easy on your thigh muscles and the Impact Brake System not only helps you to slow down, but also to get to the top. The external shell construction harmonizes with the Vibram outsole and the polyurethane foam inside and damps effectively with fewer layers of rubber. The 3D-Flex system ensures high mobility, but also stabilizes. The external gaiters made of elastic Cordura are waterproof, as is the GORE-TEX® membrane on the inside. The boot is adjusted quickly and precisely with the Boa-Fit system, and if you want to get through ice & snow, you can use semi-automatic crampons.
