Retro running sneakers have taken over the streets — but the wrong socks can ruin the whole look. Here's how to get the pairing right, straight from Copenhagen.
The retro runner is no longer a trend. It's a uniform. Whether it's a silver-mesh ASICS GEL-Kayano, a grey New Balance 990 or a slim Adidas SL72, the chunky-yet-technical running shoe of the late 90s and early 2000s has become the default sneaker of men who care about how they dress.
But here's what most people get wrong: the sock.
A retro runner is designed to be seen with a sock. The silhouette sits low on the ankle, the tongue is padded, and the whole shoe was built in an era when nobody — nobody — wore invisible socks to go running. Pair a GEL-Kayano with a no-show sock and you get a strange, bare-ankled look that fights the shoe's entire history. Pair it with a proper ribbed crew sock, and suddenly the outfit makes sense.
This is your guide to doing it properly.
Why retro runners demand a visible sock
Retro runners are technical objects. Layered mesh, reflective overlays, visible gel or foam units — there's a lot going on below the ankle. A visible sock does two things for that.
First, it gives the eye a place to rest. A few centimetres of white ribbed cotton between the trouser hem and the sneaker collar acts like a frame around the shoe. Stylists call it a "break" — the same principle as a shirt cuff showing under a blazer.
Second, it's period-correct. The runners we love from 1998–2004 were worn with white sports socks, full stop. Wearing them the same way today isn't costume — it's just coherence. The retro sock revival and the retro runner revival are the same revival.
The rules of the pairing
Keep the sock white. The shoe is already doing the work — layered colours, metallic panels, contrast midsoles. A clear white sock calms everything down and makes the sneaker look more expensive, not less. This is also why an off-white or "clear white" base works better than optic bleached white: it sits closer to the aged mesh tones of a retro runner.
Show 5–10 centimetres of sock. Cuff or pinroll your trousers so the sock is genuinely visible, or wear shorts and let the crew length speak for itself. A sock that only peeks out looks accidental. A sock that shows properly looks intentional.
Choose a ribbed, terry-cushioned crew — not a thin dress sock. Retro runners have volume. A flimsy sock disappears inside them and wrinkles at the ankle. A cushioned sports sock with a ribbed leg holds its shape all day and fills the collar of the shoe the way it was designed to be filled.
And if you want to level up: match the stripe to the shoe.
Matching stripes to your sneakers
The classic double-stripe sports sock is the easiest way to tie a whole outfit together, because the stripe gives you a colour to echo — in the shoe, the shirt or nowhere at all. Here's how we'd pair the four stripes from our new Athletique Classique Clean Stripes 6-pack:
New Blue — for silver and ice-blue ASICS. The powder-blue mesh of a GEL-Kayano 14 or GEL-1130 with a New Blue stripe is the definitive 2026 pairing. Tonal, sporty, effortless. If you own one retro runner and one striped sock, make it this combination.
Henri Blue — for grey New Balance. The muted, dusty navy of the Henri Blue stripe was made for grey suede and mesh — a 990, 991 or 2002R. It reads more grown-up than a bright stripe, which suits the New Balance crowd perfectly.
Grass Green — for cream and gum-sole runners. Against an off-white or cream sneaker — an SL72, a Samba, a cream 574 — a green stripe adds just enough colour to feel considered. Bonus points with olive or ecru shorts in summer.
Red Moon — for white leather and vintage court shoes. Red stripes are the most classic sports-sock look of all, straight out of the 70s. They wake up an all-white sneaker and sit beautifully against denim.
The beauty of the double stripe is restraint: two thin bands of colour on a white leg. It signals sport without shouting, which is exactly the register a retro runner lives in.
Crew socks and shorts: the summer version
The retro-runner-plus-crew-sock formula works twelve months a year, but summer is where it earns its keep. Navy drawstring shorts, a heavy white tee, striped crew socks pulled up, retro runners. That's the whole outfit — four pieces, done.
The proportions matter more than the pieces: shorts ending above the knee, sock ending mid-calf, a deliberate strip of leg between them. It's the look you'll see across Copenhagen every summer, and it works because every element is simple and only one element — the stripe — carries colour.
What to look for in the sock itself
Since the sock is now a visible part of the outfit, quality shows. A few things separate a sock that looks sharp at 8 in the morning from one that's sagging by lunch:
Combed or organic cotton with real density, so the white stays white and the rib stays crisp through washing. An elasticated rib that runs the full leg, so the sock stands up on its own instead of pooling at the ankle. A cushioned terry sole, because retro runners are running shoes — the comfort should match. And a flat toe seam, which you'll appreciate on long days.
All six pairs in the Clean Stripes 6-pack are knitted this way — heavy, ribbed, cushioned — because a sports sock that's built to be seen should also be built to last. If you prefer your white socks without stripes, our guide to white sneaker socks covers the plain-white essentials.
The short version
Retro runners were designed for visible white sports socks — so wear them that way. Choose a ribbed, cushioned crew in clear white, show a proper amount of leg above the shoe, and use a double stripe to echo (or deliberately contrast) your sneaker's colours. New Blue for ASICS, Henri Blue for New Balance, Grass Green for cream runners, Red Moon for white leather.
The shoes have been ready since 1999. Now the socks are too.

FAQ: Socks and retro runners
What socks should you wear with ASICS retro runners? A white ribbed crew sock with a cushioned sole. Retro ASICS models like the GEL-Kayano 14 and GEL-1130 were designed in an era of visible sports socks, so a crew length that shows 5–10 cm above the shoe is the most coherent pairing. For ice-blue or silver colorways, a blue double stripe ties the look together.
Should socks be visible with retro sneakers? Yes. Retro runners sit low on the ankle and were built to be worn with visible socks. No-show socks create a bare-ankle gap that fights the shoe's proportions, while a visible crew sock frames the sneaker and looks intentional.
Can you wear crew socks with shorts? Absolutely — it's one of the defining menswear looks of 2026. Keep the shorts above the knee, pull the sock to mid-calf, and leave a deliberate strip of leg between them. A white sock with a double stripe adds colour without effort.
What are tube socks, and are they back in style? Tube socks are ribbed, cushioned sports socks — traditionally white with coloured stripes at the top — that rose to fame in 1970s athletics. They're firmly back, driven by the retro runner revival: the shoes and the socks belong to the same era, so they've returned together.
White socks or coloured socks with sneakers? White. A clear-white base calms down a technical, multi-coloured retro runner and makes it look more expensive. If you want colour, keep it to a thin double stripe that echoes a tone in the shoe.
How many centimetres of sock should show above a sneaker? Around 5–10 cm. Enough to read as a deliberate style choice, not so much that the sock becomes the whole outfit. Cuff or pinroll your trousers to get there, or wear shorts.
