Modern outdoor socks use carefully selected fibres and technical construction to manage moisture, provide cushioning, reduce friction and keep your feet comfortable. But with so many options available, how do you choose the right socks for walking, hiking, running or mountaineering?

What type of outdoor socks do I need?

The best socks depend on your activity, footwear and the conditions you expect to encounter.

Activity socks are designed for specific activities and come in different weights, from lightweight socks for warm-weather walking and running to thicker winter walking socks for cold conditions. Look for descriptions such as Run, Hike, Trek and Mountain to help narrow your choice.

Liner socks are thin socks designed to be worn underneath another pair. They can help reduce friction between your foot and outer sock, making them a useful option if you are prone to blisters. They are also valuable on multi-day trips when you can change your liners regularly.

Compression socks provide additional support and can be useful for circulation, recovery and comfort.

Waterproof socks are designed to keep water out while remaining breathable. They are particularly useful for wet conditions, mountain biking, walking and other activities where keeping your feet dry is important.

Why choose technical walking socks?

Technical socks are designed specifically for active feet. Your feet generate considerable heat and perspiration during exercise, so good hiking socks should help move moisture away from the skin while staying securely in place.

Look for features such as flat seams, elasticated sections, supportive arch zones and cushioning around the heel and toe. These reduce friction, prevent bunching and provide additional protection in high-impact areas.

Some technical socks also have left and right-specific designs for a closer fit, while toe socks use individual compartments to allow natural toe movement and potentially reduce friction between the toes.

Getting the correct size is essential. Your sock size may not always correspond exactly with your footwear size, so check the manufacturer's sizing information.

Which sock materials are best?

Outdoor socks commonly combine several different fibres, with each material providing specific benefits.

Merino wool is popular for walking and trekking socks because it provides excellent insulation and manages moisture effectively. It is particularly useful in cooler conditions.

Nylon and elastane add durability, stretch and shape retention, helping socks maintain a secure fit after repeated washing.

Coolmax® and other synthetic fibres are designed to wick moisture away from the foot, making them suitable for running and warm-weather activities.

Some socks also use synthetic insulation such as PrimaLoft® for additional warmth and cushioning.

The best fibre combination depends on the activity, temperature and conditions.

How high should walking socks be?

Sock height should match your footwear and the environment.

• No-show socks are suitable for warm conditions and low-cut shoes but offer little protection from abrasion, insects or vegetation.
• Ankle socks provide slightly more coverage and work well with low or mid-height footwear.
• Calf or crew socks are ideal for many walking boots, providing protection from boot abrasion, grass, bracken and nettles.
• Knee-high socks are commonly used with mountaineering boots or for activities where additional warmth, shin protection or compression is required.

Your socks should be long enough to protect your skin and stay securely in place without slipping or bunching.

Should I use waterproof socks?

Waterproof socks can be a useful alternative when you are wearing non-waterproof footwear or want additional protection in consistently wet conditions.

However, waterproof socks generally prioritise keeping water out rather than moisture management. They may therefore dry more slowly than lightweight, non-waterproof walking socks, making traditional wicking socks a better choice for some multi-day backpacking trips.

Gaiters can also help prevent water, mud and debris entering your footwear.

How do I prevent blisters and foot odour?

Wearing clean socks every day and keeping your feet clean and dry will help reduce odour and the risk of blisters. Keep toenails short and smooth to prevent them damaging your socks.

For longer walks, consider carrying spare socks so you can change if your feet become wet. On multi-day trips, allow used socks to dry thoroughly before wearing them again.

Always follow the manufacturer's washing instructions to maintain the performance and extend the life of your socks.

Choosing the right walking socks

Think about activity, terrain, weather and footwear before choosing your socks. Lightweight hiking socks may be ideal for summer walks, while merino wool or insulated socks are better suited to colder conditions.

Choose a sock height that works with your footwear, make sure you have the correct size and consider liner or waterproof socks if your activity demands additional protection.

The right walking, hiking or trekking socks will help keep your feet comfortable, dry and protected, allowing you to enjoy your time outdoors for longer.
