Socks

The best hiking socks fit close without restricting movement, cushion the sole, and manage moisture to prevent rubbing. Merino wool regulates temperature and stays comfortable over long distances, while reinforced heel and toe sections add durability. ThruDark's Regular Mountain Socks combine fine-micron merino wool with Cordura fibre reinforcement and ventilation channels, built for hiking, trekking and mountaineering.

Merino wool suits hiking well. It breathes, regulates temperature in both warm and cold conditions, and stays comfortable even when damp. ThruDark's Regular Mountain Socks are made from fine-micron merino wool, reinforced with Cordura fibre at the heel and toe and finished with Lycra for a supportive fit. Because merino wool is naturally antimicrobial, these socks can also be worn for a few days at a time and remain fresh.

Compression socks support circulation on long days on your feet, particularly on descents or during multi-day expeditions where fatigue builds. They're not a substitute for a well-fitted, cushioned outdoor sock built for friction and moisture management, though. Many hikers use compression socks as a liner or recovery layer alongside a technical hiking sock, rather than relying on compression alone for blister prevention or warmth. ThruDark's Compression Socks are Class 2 medical compression socks, built with a flat-stitch leg, cushioned sole and reinforced heel and toe for training and long days on foot.

Hiking socks should sit snug against the skin with no loose fabric, since folds and slack cause friction and blisters. Look for a fine toe seam, elastic grip sections and an in-turned cuff welt to stop slipping and rubbing. ThruDark's Mountain Socks include all three, plus a fully cushioned sole, and come in two sizes for an accurate fit.

The right socks reduce blister risk but cannot guarantee prevention, since fit, footwear and terrain all play a part. A close fit, flat seams and good moisture management cut down on the friction and rubbing that cause blisters. ThruDark's Mountain Socks use a fine toe seam and elastic grip sections to hold their shape and limit movement inside the boot.

Sock thickness should match the footwear and conditions. ThruDark's Regular Mountain Socks, with a 15cm cuff, suit hiking boots and general trail use, while the Long Mountain Socks extend to 30cm for higher ankle boots in colder or snowy conditions. Thinner, low-cuff technical socks suit trail running shoes better, giving a closer fit for faster movement.

Yes. Dedicated hiking socks manage moisture, cushion pressure points and reduce friction in ways ordinary socks do not, which lowers the risk of blisters and discomfort over distance. ThruDark's Regular Mountain Socks add Cordura fibre reinforcement at the heel and toe for durability, along with ventilation channels for breathability during long days on the trail.

Some hikers do, pairing a thin liner sock with a thicker outer hiking sock. The liner sits against the skin and moves independently of the outer sock, reducing friction at pressure points and cutting blister risk on long or demanding trails. It's not essential for every hike, but it's a proven approach for multi-day treks, mountaineering routes and anyone prone to hotspots.

Wash merino wool hiking socks on a cool, gentle cycle using a mild detergent, and avoid fabric softener, which clogs the fibres and reduces moisture-wicking performance. Turn them inside out to protect the outer surface from abrasion, and skip the tumble dryer. Air drying flat preserves the wool's shape, cushioning and natural odour resistance for far longer than harsher washing or drying methods.
