Crew socks, trainer socks, invisible socks, and men's boxer shorts — the basics that keep every training session comfortable from the ground up. The underwear and socks range covers everything you need for the gym, the run, and the everyday, built with the same attention to detail as the rest of the kit.
From ribbed-cuff crew socks that stay put during a heavy session to soft-touch cotton boxers for all-day wear, the options here are practical, durable, and designed to move with you. Packs of three and five mean you can stock up without thinking about it — one less thing to worry about.
Who Underwear & Socks Are For
Anyone who trains regularly knows that the wrong socks or uncomfortable underwear can derail a workout fast. This range is built for gym-goers, runners, and anyone who wants reliable everyday basics that keep up with an active lifestyle — without having to think too hard about it.
Whether you're logging miles on the treadmill, lifting in the gym, or just want dependable everyday essentials, there's something here for you. The unisex sock styles work across the board, while the men's cotton boxers are a staple for daily comfort and support.
When to Use Underwear & Socks
The crew and trainer sock styles are well-suited for gym sessions and sports activities where you want cushioning, structure, and a fit that doesn't slip mid-set. The running socks with their ombre design bring a bit of style to longer-distance sessions while still doing the functional job.
Invisible socks work best when you're training in low-cut shoes or want a clean look off the gym floor. The cotton boxers are an everyday essential — reliable enough for rest days, comfortable enough to wear straight from the gym to wherever the day takes you.
Underwear & Socks Benefits
Stays in Place
Ribbed cuffs on the crew sock styles are there for a reason — they grip the leg and keep the sock where it should be. No pulling them up mid-rep, no bunching around the ankle.
Crew Coverage Where You Need It
The crew silhouette covers your ankle and lower calf, giving you a layer of protection between your skin and your shoes. It's a small detail that makes a difference during long sessions or high-impact training.
Everyday Comfort
The men's cotton boxers are made with a soft-touch cotton blend and a branded elasticated waistband for all-day support. Comfortable from morning to evening, whether it's a training day or not.
Range for Every Occasion
From invisible socks for trainer-style shoes to full crew lengths for the gym, the range covers the full spectrum of sock needs. Buying in multipacks means you've always got a fresh pair ready without having to think about it.

FAQs
What crew socks are available at Myprotein?
Crew socks come in packs of three and five, available in a range of colourways including black, white, black/white mix, and white/black/grey marl. The crew silhouette covers your ankle and lower calf, with ribbed cuffs to keep them in place during training. If you want a versatile everyday option, the MP Unisex Crew Socks 5 Pack in black is a practical choice — you get five pairs with the same stay-put fit.
What types of socks does Myprotein sell?
The range covers four sock styles: crew socks, trainer socks, invisible socks, and running socks. Crew socks are the most popular and come in the widest range of packs and colours. Trainer socks sit lower on the ankle for a cleaner look with training shoes, while invisible socks are designed to disappear inside the shoe entirely. The running socks come in a two-pack with a distinctive ombre design.
Are the socks unisex?
All sock styles in this range are unisex, designed to fit a wide range of sizes for both men and women. The men's cotton boxers are the only gender-specific product in the category. Sizing information is available on each individual product page to help you find the right fit.
What are trainer socks and invisible socks — what's the difference?
Trainer socks sit just above the shoe line, offering a low-profile look while still giving you some coverage around the ankle. Invisible socks sit even lower — they're designed to be hidden entirely inside the shoe, giving the appearance of bare feet while still protecting against friction. Both come in a three-pack in black and white options.
What are the men's boxer shorts made from?
The Men's Cotton Boxers are made from a soft-touch cotton blend, chosen for its everyday comfort and breathability. They feature a branded elasticated waistband for a secure, supportive fit throughout the day. Available in a three-pack in black, they're built as a reliable everyday staple rather than a single-use gym item.
Can I buy socks in bulk at Myprotein?
Yes — crew socks are available in both three-packs and five-packs, making it straightforward to stock up. The five-pack format is the largest available and gives you enough pairs to cover a full training week without repeating. Trainer socks and invisible socks are available in three-packs.
What are the running socks designed for?
The MP Running Socks come in a two-pack with an ombre zesty green and light lime stripe design, making them a standout choice for outdoor runs or treadmill sessions. Like the other sock styles, they're built with the same functional construction — the design adds a visual element for those who want their kit to look as good as it performs.
Who designs the Myprotein underwear and socks range?
The underwear and socks range is developed by Myprotein's in-house design team, applying the same performance-first thinking used across the broader MP apparel range. The focus is on practical construction — ribbed cuffs, correct silhouette height, and materials chosen for comfort and durability during regular training use.
What's the best sock to choose for the gym?
For most gym sessions, a crew sock is the most versatile option — the ankle and lower calf coverage keeps the sock in place during squats, deadlifts, and cardio. The MP Unisex Crew Socks 3 Pack in Black/White has ribbed cuffs that hold the sock position throughout a session, making it a solid all-round gym pick. If you prefer a lower profile, the trainer sock style works well with most training shoes.
How do I know which sock style to choose?
It comes down to your shoe type and personal preference. Crew socks suit gym training and sports where you want coverage and a sock that stays put. Trainer socks work well with mid-cut or standard training shoes. Invisible socks are best for low-cut shoes or casual wear where you don't want any sock visible. If you're running outdoors or on a treadmill and want something that looks the part too, the running socks are the natural choice.
