Socks & Underwear

Shop Sports Underwear & Socks at Myprotein

The right sports underwear and gym socks might not be the first thing you think about when you're building your kit, but they're the foundation everything else sits on. Poorly fitting underwear shifts mid-set. Socks that bunch up or slip down turn a solid training session into a distraction. The MP range is built specifically for movement — so the basics actually stay where they're supposed to, whatever you're doing.

From crew socks and ankle socks to bralettes and bikini briefs, there's a full lineup of training-ready staples across a range of colours and pack sizes. Whether you're stocking up on everyday workout socks or looking for underwear that keeps up with your training, it's all here in one place.

Who Sports Socks & Underwear Are For

Anyone who trains regularly knows that comfort and fit matter more than they get credit for. This range is designed for people who take their sessions seriously — whether that's five-day lifting splits, daily runs, or back-to-back classes. The 4-way stretch fabrics and soft-touch construction mean they move with you rather than against you, so you can stay focused on the work rather than readjusting your kit.

They're just as relevant for people who want reliable, no-fuss basics for the gym and beyond. Workout underwear and training socks that look good, feel comfortable, and hold up wash after wash — that's the brief. The range covers both women's and men's styles, with unisex sock options that work for everyone.

When to Use Socks & Underwear

These are everyday training essentials, not occasion-specific kit. Wear them to the gym, out for a run, to a yoga class, or just as comfortable day-to-day basics. The crew socks are particularly well suited to gym sessions and outdoor training where you want ankle coverage and a secure fit that won't slip during movement. Ankle socks work well for lower-profile trainers where you'd rather not see the sock above the shoe line.

For underwear, the key is matching the style to your training. Bikini briefs and thongs are popular choices for legging-based workouts where visible lines are a consideration — the no-VPL styles are built specifically for that. Bralettes offer light, wireless coverage that's ideal for lower-intensity sessions, stretching, and active rest days. Pack your bag once, and you've got the essentials sorted.

Socks & Underwear Benefits

Stays in Place During Training

Ribbed cuffs on the crew and ankle socks are designed to grip and hold position through movement, so you're not constantly pulling them up mid-session. The underwear uses 4-way stretch fabric that moves with your body rather than shifting out of place, keeping everything secure from warm-up to cool-down.

Soft-Touch Fabric That Doesn't Irritate

Rough seams and stiff fabrics are a distraction you don't need when you're training. The soft-touch materials used across the bralettes and briefs are chosen specifically to reduce irritation against the skin, so discomfort doesn't become a reason to cut a session short.

Full Range of Motion

The 4-way stretch construction across the women's underwear range means there's no restriction or pulling during squats, lunges, or any other compound movements. It's the kind of thing you only really notice when it's missing — once you're used to kit that moves with you, there's no going back.

Practical Pack Formats

Socks come in 2, 3, and 5-packs, and underwear in 3 and 5-packs, so you can stock up without thinking about it. Multiple colourways across every style mean you can mix and match or keep things simple with a solid-colour pack — whatever works for your kit drawer.

FAQs

What sports underwear and socks does Myprotein offer?

Myprotein's MP range covers a full selection of training-ready basics, including crew socks, ankle socks, bikini briefs, thongs, bralettes, and boxers. Socks are available in 2, 3, and 5-packs; underwear comes in 3 and 5-packs. There's a strong range of colourways across all styles — from neutrals and classic black and white to seasonal shades — with both women's-specific and unisex options available.

What are sports socks, and are they different from regular socks?

Sports socks are designed specifically for active use, with construction details that regular everyday socks typically skip. The MP crew and ankle socks feature ribbed cuffs that hold the sock in place during movement — useful when you're training and can't afford to stop and sort your kit. They're also made to be worn repeatedly through tough wash cycles, keeping their shape and fit over time.

What's the difference between gym socks and workout socks?

The terms are largely interchangeable — both refer to socks designed to stay comfortable and secure during physical activity. The main distinctions come down to cut and coverage. Crew socks sit higher on the leg, covering the ankle and lower calf, which suits gym training, running, and outdoor use. Ankle socks sit lower and are better suited to low-profile trainers or those who prefer a minimal look.

What's the best gym underwear for training in leggings?

The MP Women's Mid Rise No VPL Thong (3 Pack) is designed specifically for this — the no-VPL construction sits seamlessly under tight-fitting leggings without showing lines. For those who prefer a brief style, the MP Women's Mid Rise Bikini Brief is worth considering: its soft-touch fabric reduces irritation and 4-way stretch allows full movement, making it a solid choice for any legging-based workout.

Which socks would you recommend for gym training?

The MP Unisex Crew Socks are a reliable go-to for gym use. The crew silhouette covers the ankle and lower calf, and ribbed cuffs keep the sock in place through sets and circuits. They're available in multiple colourways and pack formats — the 3-pack in white is one of the most popular options for keeping your kit drawer well stocked.

Is there workout underwear available for men?

Yes — Men's Boxers are available in 3-packs and 5-packs in black, covering the basics for everyday training use. The range is straightforward and designed for comfort and durability through regular gym sessions and washing cycles.

What bralette styles are available?

Two bralette styles are available for women: a V-neck bralette and a scooped neck bralette. Both feature soft-touch fabric and 4-way stretch construction for comfortable, unrestricted movement. They're available in a range of colourways including black, white, fudge, and deep berry. These are wireless, light-coverage styles suited to low-to-moderate intensity training, stretching, and active rest days.

Who designs the MP socks and underwear range?

The MP socks and underwear range is developed by Myprotein's in-house design team, focused on creating performance-ready basics that work for everyday gym-goers and serious athletes alike. The construction details — from ribbed sock cuffs to 4-way stretch fabrics — reflect input from people who actually train, rather than an afterthought approach to activewear basics.

What pack sizes are available for training socks and underwear?

Socks are available in 2-packs, 3-packs, and 5-packs depending on the style. Underwear comes in 3-packs and 5-packs across both women's and men's styles. Buying in packs means you can keep the gym bag well stocked without repeated single purchases — useful when you're training multiple times a week and running through kit regularly.

Are there colour options across the socks and underwear range?

There's a solid range of colourways across all categories. Socks come in options including white, black, neutral tones, and mixed packs (white, black, and grey marl). Women's underwear ranges from everyday neutrals — white, black, grey — to richer shades like deep berry, deep chocolate, and warm cream. There are also seasonal colourways available, so it's worth checking the current range for the latest additions.
