Hiking socks are one of the most overlooked pieces of hiking kit. Walkers who’ll spend £150 on waterproof boots will happily pull on a pair of ordinary sports socks, and then wonder why they have blisters at the end of the day.
The mechanics are simple: moisture softens skin, softened skin blisters more readily, and the right sock manages moisture and reduces friction. The wrong sock, especially cotton, absorbs sweat and stays wet, dramatically increasing blister risk.
Here’s what we’d actually recommend.
Best Hiking Socks UK
Darn Tough Hiker Micro Crew Midweight: Best Overall
RRP: ~£25 | View on Amazon UK
Darn Tough is an American brand from Vermont that makes all its socks in-house and backs them with a lifetime unconditional guarantee, if they wear out, get a hole, or lose their cushioning, the company replaces them. That level of confidence in the product is backed by real quality: the Hiker Micro Crew uses a tight 1⁄4 cushion construction in merino-nylon blend that is genuinely durable.
The fit is excellent, snug without restriction, with the heel cup staying in place during long days. The merino content provides good odour resistance and moisture management. In six months of UK hillwalking use, these didn’t develop a single thin patch.
Pros: Lifetime guarantee, excellent durability, comfortable, merino performance Cons: More expensive upfront than budget options Best for: Regular hillwalkers, those who want the best-value long-term sock
Smartwool Hike Classic Edition Light Cushion: Best Lightweight
RRP: ~£22 | View on Amazon UK
Smartwool’s Hike Classic Light Cushion is the choice for walkers in trail shoes or for warm summer days when a midweight sock would be too warm. The 1⁄4 cushion construction is minimal enough to work with lighter footwear without creating pressure, while still providing the merino moisture-wicking and odour resistance benefits.
The reinforced heel and toe improve durability in the areas that wear fastest. The sock stays in place during long days. A reliable and well-priced option for lighter-use hiking.
Pros: Light, works with trail shoes, reliable merino performance Cons: Less padding for rocky terrain or heavy boots Best for: Summer day hikes, trail shoe users, warmer conditions
Bridgedale Midweight Merino Performance: Best British Brand
RRP: ~£20 | View on Amazon UK
Bridgedale is a UK brand that understands British conditions, and their Midweight Merino Performance is designed for the varied terrain and changeable weather that UK walkers face. The merino-nylon blend hits the right balance between natural fibre performance and synthetic durability. Cushioning is in the right places, heel and ball of foot, without adding bulk elsewhere.
The fit is slightly roomier than Darn Tough, which suits walkers with wider feet. Available in a range of heights: ankle, crew, and full length, the crew is the standard recommendation for UK hillwalking.
Pros: Well-made UK brand, good fit for wider feet, reliable merino blend Cons: Not quite as durable as Darn Tough over extended use Best for: Regular UK hillwalkers, those who prefer a UK brand
Icebreaker Hike Medium Crew: Best Premium Merino
RRP: ~£28 | View on Amazon UK
Icebreaker uses high-quality New Zealand merino across their range, and the Hike Medium Crew shows it. The cushioning is generous across the full sole with lighter knitting in the upper, comfortable across a full day on rough ground. The merino quality means excellent temperature regulation and very good odour resistance.
Slightly less durable than Darn Tough (no lifetime guarantee) but the comfort and merino quality are among the best available. A good option for walkers who prioritise comfort over maximum durability.
Pros: Premium merino quality, excellent comfort, good temperature regulation Cons: Premium price, warranty less comprehensive than Darn Tough Best for: Comfort-first walkers, those who do long days on rough terrain
Thorlos Experia XCCU: Best for Blister Prevention
RRP: ~£18 | View on Amazon UK
Thorlos specialises in performance socks with targeted padding, and the Experia XCCU has a clinically developed cushioning system designed specifically to reduce friction and pressure at blister-prone points. The combination of acrylic and merino fibres manages moisture effectively while the construction keeps the sock in place.
If you’re a habitual blister sufferer, these are worth trying. The targeted padding approach addresses the specific contact points that cause problems for most hikers. Not the most luxurious feel of the options here, but effective at their primary job.
Pros: Targeted blister-prevention padding, clinically developed design Cons: Less refined feel than pure merino, bulkier than lightweight options Best for: Blister-prone hikers, those who struggle with friction despite good boots
Sock Care and Longevity
Washing: Turn inside out before washing. Machine wash on a cool cycle (30–40°C) with a gentle detergent. Avoid fabric softener, it coats fibres and reduces wicking performance. Hang dry or tumble dry on low heat.
Drying between uses: On multi-day trips, dry socks fully between days. Hanging inside the tent overnight is usually sufficient; wearing damp socks into the next morning accelerates degradation.
Storage: Keep hiking socks in a separate bag or drawer from everyday socks. It sounds trivial but cotton socks occasionally make their way into hiking packs, with predictable results.
Rotation: Owning 3–4 pairs and rotating them extends the life of each pair significantly. Washing and full drying takes 24–48 hours; a rotation prevents the temptation to use still-damp socks.
