Scarpa has been perfecting Manta Tech for almost three decades and the current Manta Tech climbing boots now feature Gore-Tex waterproofing to provide adequate weather protection. This Gore-Tex material not only provides waterproof protection but also provides insulation allowing you to retain heat at high altitudes. Durable Perwanger suede covers the upper ensuring durability and flex zones facilitate mobility when walking up and down mountains. Vibram rubber provides reliable traction outsole , and it can be replaced without affecting the boots' compatibility with semi-automatic crampons.
