Advice : Use the foot sizer from SIDAS to help you find the right size
The Alpine Expert II GTX from the brand Lowa are high-end mountaineering boots for men that combine comfort, precision, and durability to help you conquer the most demanding peaks.
Ideal for expeditions, high mountain climbs, mixed terrain, and the most technical via ferratas, they will meet the needs of the most experienced mountaineers. Their suede upper is wrapped in a waterproof and breathable GORE-TEX® membrane, offering optimal protection against the elements.
Paired with Primaloft® 400 g insulation, this construction guarantees pleasant warmth, even in freezing conditions, so nothing stops your ambitions. On the sole side, the Vibram® Alp Trac® Ice excels in high mountain environments: this specific rubber and its deep lugs ensure exceptional grip, while the climbing zone at the toe allows precise and stable footholds. The sole is also designed to maximise terrain feedback thanks to its low profile and thin structure, ideal for feeling the rocks and adjusting your movements with precision.
The lacing system is a major asset. With its two distinct zones, a precise X-lacing and rolling eyelets that facilitate adjustment, you benefit from perfect support and even tightening, essential for long ascents. The Lowa Flex™ and Flex Fit™ technologies ensure pressure points are distributed evenly, offering unparalleled comfort even after hours of effort.
Designed for high mountain use, these boots are compatible with automatic crampons, making them ideal for glacier climbs and technical passages. Their heel shock absorber adds an extra touch of comfort, reducing impacts during descents.
With their precise anatomical fit, ability to keep your feet warm and dry, and flawless grip, the Alpine Expert II GTX from Lowa are essential allies for your boldest alpine adventures. Whether on rocky terrain, glaciers, or steep trails, they will accompany you with reliability and performance.
