Monitor Onyx is a durable and functional trekking boot developed for cold and demanding environments where warmth, comfort, and weather protection are essential. A waterproof Monitex membrane keeps feet dry while allowing breathability for all-day comfort. The winter-lined construction with 200 g Thinsulate provides effective insulation without adding bulk, making it ideal for outdoor work or long walks in cold conditions. The ripstop upper is lightweight yet highly durable, offering flexibility and resistance to wear. Quick lacing can be easily adjusted and stored in a tongue pocket for a clean look. The EVA midsole ensures shock absorption and comfort, reducing strain on feet and joints, while the rubber outsole delivers reliable grip on both wet and dry surfaces. A memory foam insole adapts to the foot for added comfort and support. With a normal fit, Onyx suits a wide range of users. Like all Monitor shoes, it is designed with a focus on function, quality, and comfort, based on extensive experience and anatomical knowledge. The result is a warm, waterproof, and versatile boot for both work and leisure.
