About the Bridgedale Explorer Heavyweight Merino Comfort The Bridgedale Explorer Heavyweight Women's Hiking Sock is highly cushioned and insulated, making it perfect for hiking, walking, and trekking in cold, wintery temperatures. At a mid-calf/boot length, this sock is ideal for wearing with hiking boots and guarantees to keep your feet warm. It also features shock zones which are strategically-placed padded areas to absorb impact and provide extra comfort. As part of Bridgedale's Merino Comfort range, the Explorer Heavyweight is made from a blend of merino wool and synthetic fibres. The increases the longevity of the sock and encourages faster moisture wicking than merino wool alone. One of the synthetic fibres used is called Coolmax: it is a very soft yarn that has 4-way channel construction to draw moisture away from the body whilst trapping air in for extra insulation. This promises to keep your feet dry and warm no matter the conditions. The Explorer Heavyweight incorporates Bridgedale's Comfort Fit, which achieves a close supportive fit around the heel and foot, and a slightly looser fit around the calf. This allows the cuff to be worn up or down, depending on personal preference. This hiking sock has Y heels to keep the heel in place whilst walking, and also features a flat toe seam to prevent rubbing. On top of all this, these socks feature Bridgedale's Thermo Fit technology, which ensures they maintain their original size and shape, wash after wash, for that same reliable fit. All these elements combine to create a sock that is highly durable, comfortable and insulated. This is perfect for mountain hikes, winter walks, and many other cold-weather activities. With guaranteed warmth and supreme moisture-wicking abilities, the Explorer Heavyweight from Bridgedale promises to keep your feet dry and comfortable in even the coldest conditions and environments.
