The right men's underwear and crew socks aren't an afterthought — they're the foundation of a comfortable training session. From deadlifts to daily wear, what's closest to your skin matters. The range covers everything from crew and ankle socks to trainer and invisible styles, alongside cotton boxer shorts built for all-day comfort.
Whether you're after gym socks that stay put through a heavy session or everyday underwear that moves with you, there's a format and fit for every need. With multi-pack options across colours and silhouettes, it's easy to stock up and keep things simple.
Who Underwear & Socks Are For
Gym-goers and everyday wearers alike will find something here. If you're spending long hours on your feet — whether that's on a training floor, a run, or a full day at work — well-fitted athletic socks with ribbed cuffs and proper ankle coverage make a real difference to comfort and stability.
The men's underwear range suits anyone after reliable, breathable basics. Soft-touch cotton boxers with a branded elasticated waistband deliver the kind of everyday support that holds up from morning workouts to late evenings, without fuss or compromise.
When to Use Underwear & Socks
Workout socks earn their place in the gym bag, but the range isn't limited to training days. Crew socks work just as well for commuting, casual wear, or anything in between. The multi-pack formats — three and five packs across styles — make it easy to rotate through the week without running low.
Running-specific styles like the Running Socks are designed with performance in mind, making them a smart choice for cardio sessions or outdoor runs. For gym sessions where you want a low-profile option, trainer and invisible sock styles sit neatly beneath trainers without bunching or slipping.
Underwear & Socks Benefits
Multi-Pack Value
Stocking up is straightforward with three-pack and five-pack options across crew, ankle, trainer, and invisible sock styles. The underwear range follows the same logic — three-packs of cotton boxers keep your drawer sorted without repeated reordering.
Styles for Every Occasion
From crew socks that cover the ankle and lower calf to invisible styles that disappear inside your shoes, the range covers every silhouette. Colourways include clean whites, classic blacks, and mixed packs with grey marl — practical for matching any kit.
Comfortable, Gym-Ready Fit
Ribbed cuffs on crew and trainer styles keep socks in place during movement, so they're not sliding down mid-set. The cotton boxer shorts use a soft-touch blend and a supportive elasticated waistband — the kind of fit you don't have to think about.
Everyday Wearability
These aren't single-use gym pieces. The construction and colourways work just as well off the gym floor — commuting, working, or running errands. Durable, washable, and built to keep their shape across regular use.

FAQs
What types of socks are available in the range?
The range includes crew socks, ankle socks, trainer socks, invisible socks, and running socks — available in three-pack and five-pack formats. Crew socks cover the ankle and lower calf with ribbed cuffs to keep them in place, while invisible and trainer styles sit low inside your shoes. Colourways span white, black, grey marl, and mixed packs, so there's an option for every preference and use case.
What are crew socks and how do they differ from ankle socks?
Crew socks feature a taller silhouette that covers the ankle and extends up the lower calf, offering more coverage and a secure feel during training or everyday wear. Ankle socks sit closer to the ankle with a lower cuff profile — a more minimal look that still provides coverage without the height. Both styles are available in multi-packs, so you can mix based on what you're wearing them for.
Are these gym socks or are they suitable for everyday wear too?
Both. The socks are designed to handle gym sessions and daily wear without compromise. Ribbed cuffs on crew and trainer styles keep things in place during exercise, while the construction holds up well for commuting, casual wear, and everything in between. The running socks are the most performance-specific option, built with active use in mind.
What men's underwear is available?
The range currently includes men's cotton boxer shorts in a three-pack. Made from a soft-touch cotton blend with a branded elasticated waistband, they're designed for all-day comfort — reliable enough for gym days and everyday wear alike. Available in black.
What's a good sock option if I want something versatile?
The MP Unisex Crew Socks (3 Pack) in White are a solid all-rounder. The crew silhouette covers the ankle and lower calf, ribbed cuffs keep them in position, and the clean white colourway pairs easily with most training and casual kit. For those who want more variety in a single purchase, the five-pack version gives you more to rotate through the week.
Do the socks come in mixed colour packs?
Yes. Alongside single-colour packs in white and black, there are mixed three-packs available — including a white, black, and grey marl combination in the crew sock range. The Black/White crew sock three-pack is another multi-tone option if you want variety without managing separate orders.
Are these socks unisex?
Most of the sock range is labelled unisex, covering crew, ankle, trainer, and invisible styles. The men's cotton boxers are cut specifically for men. Check individual product listings for sizing guidance to find the right fit.
Who designs the Myprotein clothing and accessories range?
Myprotein's in-house design team develops the clothing and accessories range, drawing on feedback from athletes and everyday gym-goers to shape fit, function, and style. The focus is on practical, durable pieces that work as hard in the gym as they do outside it.
How do I choose between trainer socks and invisible socks?
Trainer socks have a slightly higher profile than invisible styles, sitting just above the shoe line with a subtle cuff. Invisible socks are designed to disappear entirely inside low-cut trainers with a no-show silhouette. If you're wearing low-profile trainers and want zero sock visibility, invisible styles are the better fit. Trainer socks offer a little more coverage while still keeping a low profile.
What pack sizes are available across the range?
Socks come in two-pack, three-pack, and five-pack options depending on the style — with three-packs being the most common across crew, ankle, trainer, and invisible styles. The running socks come in a two-pack. Men's cotton boxers are available as a three-pack. Multi-pack formats make it easy to build up a rotation without frequent reordering.
