The basics matter. Men's boxers and socks might not be the most glamorous part of your kit, but get them wrong and you'll know about it — especially mid-session. This collection covers everything from everyday cotton boxers to crew, ankle, trainer, and invisible socks, so you can stock up on the essentials without compromise.
Whether you're after men's crew socks for the gym or a multipack of boxers to see you through the week, there's a practical, well-made option here. Multipacks keep things simple — grab a 3-pack or 5-pack and you're sorted.
Who This Collection Is For
If you train regularly, you already know that worn-out basics are a distraction you don't need. This range is built for men who want underwear and socks that hold up — whether that's in the gym, on a run, or just getting through a long day on your feet.
It's also a solid choice if you're stocking up on men's underwear and socks in one go. The unisex sock styles suit anyone after a reliable everyday option, and the variety of cuts — crew, ankle, trainer, invisible — means there's something to match whatever you're wearing.
When to Wear These Essentials
Men's crew socks are the go-to for training days — they sit comfortably above the shoe and stay put through workouts. Trainer and invisible socks work better when you want a low-profile look with trainers or casual shoes, while ankle socks sit neatly in the middle. The running socks in the range are cut specifically for higher-impact activity, making them worth reaching for on cardio days.
The cotton boxer briefs pull double duty — comfortable enough for everyday wear and well-constructed enough to handle active days too. When you've got a range of silhouettes and lengths available, it's easy to match the right sock to the right occasion without overthinking it.
Key Features
Soft-Touch Everyday Comfort
The men's cotton boxers are made from a soft-touch cotton blend that feels comfortable from the first wear. An elasticated branded waistband keeps everything in place without digging in — exactly what you want from a daily essential.
Ribbed Cuffs That Stay Put
The crew socks feature ribbed cuffs that grip the lower leg and stop the sock from sliding down during the day or mid-workout. It's a small detail that makes a real difference when you're moving.
Multiple Silhouettes, One Collection
From crew to invisible, the sock range covers every length you'll need across your wardrobe. Each cut is designed to complement a specific shoe type, so you're not just grabbing any sock — you're picking the right one.
Multipacks Built for Real Life
Three-packs and five-packs mean fewer trips to restock and more variety to hand. The multipack format works across all the sock styles in the range, making it easy to build up a complete drawer of men's socks in one go.

FAQs
What men's socks are available?
The range includes crew, ankle, trainer, invisible, and running socks — all available in multipacks. Crew socks are the most versatile option for training and casual wear, covering the ankle and lower calf. Trainer and invisible styles sit lower in the shoe for a minimal look, while the running socks are tailored for higher-impact sessions.
Are the crew socks unisex?
Yes — the crew socks are designed to be unisex and come in a range of colourways including white, black, and mixed packs. The ribbed cuff construction and crew silhouette make them a practical everyday option for anyone.
What are the men's boxers made from?
The Men's Cotton Boxers are made from a soft-touch cotton blend, which gives them that comfortable, worn-in feel from day one. The elasticated waistband is branded and built to sit securely without being restrictive.
How should I care for the socks and boxers?
Always check the care label on the individual product, but as a general rule, machine washing on a gentle or cool cycle will keep the fabric in good shape for longer. Avoid tumble drying on high heat to preserve the elasticity in the waistbands and sock cuffs.
What sizes are available?
Sizing varies by product, so it's worth checking the size guide on each individual product page before ordering. The socks are typically available in standard size ranges to suit most fits, and the boxers come in a range of waist sizes.
Who designed the underwear and socks?
Everything in this range was designed by Myprotein's in-house design team. The focus was on practical, durable basics that work as hard as the rest of your kit — nothing overcomplicated, just well-thought-out essentials.
Can I wear these socks for running?
The running socks in the range are the best choice for higher-impact activity — they're cut specifically with running in mind. For general gym training, the crew or ankle socks are a solid everyday option that holds up well across most types of exercise.
Do the invisible socks stay in place in trainers?
Yes — the invisible socks are designed to sit low in the shoe without slipping, making them a good pick for trainers or casual footwear where you want a no-show finish. Like the rest of the sock range, they're available in 3-packs so you can keep a few pairs on rotation.
