Maximum fit comfort thanks to the gusseted tongue and soft snow gaiter on the collar. Exceptional walkability thanks to the innovative Double Heel\u2122 construction: the pronounced dual rear lug geometry increases braking effect on descents and allows smoother roll-through, reducing muscle fatigue. Durability and lightness coexist in harmony thanks to the new sole\/midsole package with external Rubber Guard\u2122 shell construction and internal foam material for enhanced cushioning and lightness derived from reduced rubber layer use. The last is Ergonomic: snug and precise with integrated TPU shells at toe and heel reinforcing the upper. The 3D Flex System Evo\u2122 directional flex with shaped ankle bone and anti-abrasion protection allows better foothold control and perfect ankle mobility. The lacing protection gaiter at the toe protects against abrasion. The midsole is semi-crampon compatible, the sole adopts a Vibram\u00ae SpringLug Tech tread with Impact Brake System lugs for greater adaptability to hard rock surfaces. Mountaineering in perfect harmony.        <\/p>\n<\/div>\n<p><b>Waterproof membrane: <\/b>GORE-TEX Performance Comfort<\/p>\n<p><b>Structure: <\/b>Glass fiber reinforced nylon<\/p>\n<p><b>Lining: <\/b>GORE-TEX Performance Comfort<\/p>\n<p><b>Midsole: <\/b>None<\/p>\n<p><b>Patent: <\/b>Impact Brake System\u2122, 3D Flex System Evo\u2122<\/p>\n<p><b>Sole: <\/b>Vibram sole with SpringLug technology and Impact Brake System\u2122<\/p>\n<p><b>Upper: <\/b>Water-repellent high-tenacity Nylon 6.6 with abrasion-resistant HoneyComb Guard protection<\/p>\n<\/div>\n<p>+ Soft fabric snow gaiter<br \/>\n+ Gusseted tongue for maximum fit comfort<br \/>\n+ Snug and precise Ergonomic shape with TPU shells integrated into the toe and heel to reinforce the upper<br \/>\n+ 3D Flex System Evo\u2122 directional flex with shaped ankle bone protected by anti-abrasion TPU layer: allows better foothold control and perfect ankle mobility<br \/>\n+ HoneyComb Guard\u2122 fabric upper with monofilament thread and anti-abrasion TPU film reinforcements for protection and lightness<br \/>\n+ Hook lacing in upper section, webbing lacing in lower section with lower anti-abrasion gaiter for use with crampons<br \/>\n+ Semi-crampon compatible midsole for use with semi-automatic crampons on ice or snow<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<div class=\"row justify-content-center product-details\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Ultra-lightweight technical hiking boot ideal for via ferratas, trekking, glacier crossings and mixed terrain.
