Comfort isn’t a luxury when it comes to underwear and socks — it’s a daily requirement. The right pieces can make a long train journey, a chilly morning run, or a full day at the office feel notably better. Think of undergarments as the foundation of an outfit: if the foundation is solid, everything above it performs better. That’s why choosing proper long johns, thermal underskirts, compression sleeves, or sturdy running socks is worth a little homework.
Here you’ll find a walk-through of standout stores and product types available to shoppers in the UK, highlighted picks like merino long johns and neoprene supports, tips to choose the best items for your activity, and practical care advice. I’ll focus on stores mentioned in the supplied data — such as Lindex and RunningXpert — and also point you to other UK retailers that carry similar, high-quality options.
Lindex is known for its clean designs and reliable basics, and in the underwear category it brings classic options like underskirts and merino long johns. Merino is a superstar fabric: it regulates temperature, resists odors naturally, and feels soft against skin. Lindex’s long johns are the kind you reach for when the thermometer dips below about 50°F and you want a layer that breathes as you move.
If you’re a commuter who doesn’t want to overheat on the walk to the station, or an outdoor worker layering up for cold conditions, merino long johns from Lindex are a smart pick. They pack warmth without bulk and match well under jeans or work trousers. They’re also a go-to for anyone prone to sweating who still needs insulation.
Underskirts (thermal slips) are often associated with women’s wear, but in many wardrobes a lightweight underskirt or slip can be adapted as a thermal base layer under looser garments. Lindex’s options are slim, breathable, and designed to add warmth without altering silhouette or movement. Think of them like a thin blanket that keeps your core cozy.
RunningXpert specialises in performance accessories that keep athletes moving. Their line-up includes items like the Endurance Protech Neoprene Ankle Support, an open knee support designed for running comfort, and CEP compression ankle sleeves. These items aren’t underwear in the traditional sense, but they’re essential “under layers” for many athletes: they stabilize, protect, and sometimes speed recovery.
Neoprene supports from RunningXpert add a snug, warming layer around joints. The ankle and knee supports are great if you want mild compression plus heat retention — useful when you’re nursing a niggle, running in cold weather, or simply want confidence in uneven terrain. Neoprene won’t replace physiotherapy, but it’s a functional first line of defense.
CEP’s compression ankle sleeves focus on graduated compression, which helps blood flow and can reduce swelling during long runs or intense training blocks. Runners often use these during races or post-run recovery to feel fresher the next day. They’re lightweight, compact, and easy to pack for travel.
Beyond Lindex and RunningXpert, the UK market offers many places to find quality underwear and socks. Marks & Spencer is famous for dependable everyday underwear and long johns; Decathlon stocks technical thermals and affordable running supports under brands like Kalenji and Wedze; Wiggle and Runners Need focus on athlete-specific socks and compression gear; SockShop and Happy Socks cover specialist and fashion-forward sock options; John Lewis and Next offer a broad mix of lifestyle and performance base layers. Each retailer brings a slightly different angle — price, technical detail, or style.
If you want specialist merino pieces, consider brands such as Icebreaker and Smartwool (sold through retailers in the UK). For technical running accessories and compression wear, check Wiggle, Runners Need, and online specialists like RunningXpert. Decathlon is unbeatable for budget-friendly, technical basics for hiking and running.
Understanding fabric is half the battle. Merino wool excels at temperature regulation and odor control, making it a top choice for long johns and base layers. Synthetic blends like polyester and elastane are durable, dry fast, and maintain shape, which is ideal for compression sleeves and running socks. Neoprene offers insulation and mild compression for supports. Cotton feels soft but retains moisture — fine for short casual wear but not optimal for high-output activity.
Merino: great for everyday warmth, natural odor resistance, and comfort. Synthetic: better for high-sweat scenarios because it wicks moisture rapidly and dries faster. For many people, a merino-synthetic hybrid provides the best balance: natural feel with athletic durability.
What you need depends on what you do. Are you a runner looking to reduce shin irritation? Choose breathable socks with targeted cushioning and consider a compression sleeve for recovery. Hiking in variable weather? Midweight merino long johns plus durable hiking socks will keep your feet and core comfortable over long miles. Commuter or office worker? Thin merino or a light synthetic base layer under your trousers is discreet and effective.
Runners often prioritize fit and moisture control. Low-profile socks with reinforced heel and toe, and arch support are the sweet spot. Complement those with a neoprene ankle support or a CEP compression sleeve if you’ve had past injuries or want to prevent swelling on long runs.
When temps drop below about 50°F, midweight merino long johns are a go-to. Layer them under trousers or waterproof shells. Combine with thick, cushioned wool-blend socks for warmth on hikes. If you’re working in cold conditions, underskirts or thin thermal slips add warmth without bulk.
A snug but not restrictive fit is the golden rule for base layers and supports. Long johns should sit close to the skin so they trap air and move moisture away; they shouldn’t bind at the waist or crotch. Compression sleeves need to follow the limb’s contour and feel firm, not painful. When in doubt, use sizing charts and measure around the broadest part of your calf, ankle, or hip in inches for the most accurate fit.
Use a flexible tape measure and record inches. For waist sizing on long johns, measure around the natural waist in inches. For ankle and calf supports, measure the circumference of the ankle and the widest part of the calf in inches while you’re standing. Don’t guess — a few inches off can mean a support that slips or base layers that bunch up.
How you wash and dry base layers and supports affects how long they last. Merino prefers gentle cycles and air drying to keep its softness and fit. Neoprene and compression sleeves should be rinsed after heavy use and left to air dry flat away from direct heat. Treat your garments like investment pieces: a little care adds months or years to their life.
Wash merino on a gentle cycle or by hand in lukewarm water. Use mild detergent and avoid bleach. Air dry flat. For compression and neoprene supports, rinse after use, wash on a gentle setting, and avoid tumble drying — heat can break down elastic fibres. Rotate socks to let elastic rest between wears.
Some pieces are worth paying more for. A high-quality merino long john or a well-built compression sleeve can perform consistently for seasons. On the other hand, everyday socks and basic thermals can be found at affordable prices at retailers like Decathlon or basic ranges from Marks & Spencer. Think of premium items as staples that earn their cost through comfort, durability, and performance.
Save on multi-pack basic socks and generic cotton thermals if your needs are casual. Splurge on merino base layers, high-grade compression from brands like CEP, and specialized neoprene supports if you rely on them for sports or work. A balanced wardrobe will mix both approaches.
Shop around: compare product specs like material composition, weight, and sizing measured in inches. Use reviews to learn about real-world fit and durability. If you prefer trying on, department stores like John Lewis or Next often stock a mix of everyday and technical options. For specialist running gear and supports, look to RunningXpert, Wiggle, and Runners Need. For merino and lifestyle base layers, check Lindex, Marks & Spencer, or specialist outdoor retailers.
When buying online, verify sizing in inches, read about fabric blends, and check customer photos when possible. Look for detailed return policies (not covered in the FAQ here) and size guides that show measurements in inches to avoid surprises.
Ask yourself what problem you want to solve: warmth, moisture control, joint stability, or style? Choose the fabric and fit that match that need, measure in inches for accurate sizing, and pick a retailer that supports the type of product you want. Whether it’s Lindex merino long johns for a cold commute, RunningXpert supports for injury prevention, or reliable socks from SockShop, you can build a practical and comfortable underwear drawer without breaking the bank.
Buying men’s underwear and socks in the UK is more purposeful now than ever. Fabrics like merino and synthetics cater to different needs, and retailers from Lindex to RunningXpert offer focused solutions — from thermal long johns to neoprene and compression supports. Measure in inches, match the fabric to your activity, and treat your garments with gentle care. With the right choices, your base layers won’t just sit quietly under your clothes — they’ll actively improve your day.
