ReGear gear guide
Hiking socks explained: height, cushioning, materials and fit
Practical checks to help you choose second-hand gear for your next trip.
Read the guide
Choose walking socks with your footwear on. A soft, thick pair can feel good on its own yet leave too little room inside a fitted boot.
Match the height to the footwear
The sock should cover the area where the shoe or boot collar touches your skin. Crew socks extend above the ankle and suit many hiking boots; low-cut socks suit lower shoes.
What cushioning labels mean
- Light: modest padding, usually at the heel and ball of the foot; useful when space and warmth are priorities.
- Medium: more padding and warmth, with more bulk inside the boot.
- Heavy: the thickest option, mainly worth considering for cold conditions and compatible roomy footwear.
Read the material blend
Merino wool manages warmth and odour; polyester dries quickly; nylon improves durability; elastane helps the sock hold its shape. A blend balances these jobs. All-cotton socks hold moisture and dry slowly, so they are a poor first choice for active walking.
A simple fit check
- Use your foot size and the maker’s size chart.
- Line the shaped heel pocket up with your heel.
- Smooth out wrinkles, then put on your usual walking footwear.
- Walk and check for bunching or tightness. Try a thinner sock if extra padding crowds the foot.
What I would bring
For a longer day I would carry a dry spare pair inside a waterproof liner. I would test a new sock and boot combination on a short outing before taking it on a full-day walk.
