Running shorts look simple. Just pick a design you like, right?
Well, not exactly.
A single inch of inseam can change how your stride feels. The wrong length liner can turn mile eight into a friction festival, while the wrong fabric for the weather can turn your dry run into a portable sauna.
If you’re in the market for a new pair of men’s running shorts, you’ve come to the right place. This guide will break down exactly which Gymshark pairs suit your distance, pace, body type, and storage needs.
Whether you’re looking to color-match your shorts and everyday running sneakers for your easy miles, training for a marathon, or mixing gym sessions with treadmill runs, here’s how to choose your next pair of running shorts properly.
Our Top Gymshark Running Shorts For Men
Each style of running shorts has been assessed against the factors that actually matter on the road or treadmill: stable waistbands, fabric weight, anti-chafe construction, secure storage, and versatility across different training demands. With that framework in mind, here’s how our top styles perform.
1. Best for Speed & Race Day: Running 4” 2-in-1 Shorts
Best for: Tempo sessions, race day, and speed work.
Built for pace and comfort-first performance. The 4” inseam maximises stride freedom by reducing excess fabric around the quads, which can subtly interfere with hip flexion at higher speeds. At tempo or race effort, less material means less drag, less moisture retention, and fewer distractions. They don’t come at the cost of coverage, though; there’s a built-in inner-liner that minimises thigh-on-thigh friction and removes the need for separate underwear (if that suits you).

2. Best for Daily Training: Running 5” Shorts
Best for: Everyday mileage, balanced comfort, and performance.
The 5” inseam sits in the sweet spot for men’s running shorts. Enough coverage for comfort but short enough for natural stride mechanics. The lightweight perforated fabric dries quickly and avoids that heavy, clingy feeling by mile three. A zip pocket on the back keeps your phone secure without excessive bounce and is also ideal for keys or gels. No built-in shorts here, but the built-in brief liner does offer reduced friction without feeling compressive. If you run three or four times per week and want one reliable pair, start here.

3. Best for Conditioning & Cardio: Fit Repeat 6” Shorts
Best for: Steady mileage, mixed gym and run sessions.
This is a mileage-first short with a slightly more lifestyle-polished finish, ideal for anyone running regular 5K to 15Ks at steady efforts or building their running base. But also great for those weekend conditioning sessions too. The 6” inseam supports steady pacing and natural stride rhythm, but despite the longer length, the split curved hems won’t limit ROM. Then there’s the contrast waistband: stable and adjustable, fitting flushly against your waist for a boxer-brief-like comfort.

4. Best for Hybrid Training: Arrival 5” Shorts
Best for: Beginners, general fitness runs, short daily sessions.
A 5” inseam has become somewhat of a gold standard for men’s running shorts. This length allows good stride freedom while maintaining a silhouette that feels just as wearable for the gym. They’re not as ventilation-focused as pure running styles that may have mesh zones or split hems, but the classic woven structure and wearable design help these shorts transition smoothly between lifting and light cardio. If your week alternates between treadmill intervals and strength training for runners, this versatility matters.

5. Best for Extra Coverage: Sport 7” Shorts
Best for: Taller runners, beginners, or those who prefer longer inseams.
Longer inseams provide physical and psychological coverage. For new runners, knowing coverage is on your side often improves confidence. While airflow is marginally reduced compared to shorter styles, the difference is small at steady paces. For easy runs and beginner distances, this length feels familiar and safe.

6. Best for Cross Training: Hybrid 6” Shorts
Best for: Runners combining strength training and conditioning.
Built to handle dynamic movement beyond running, the Hybrid Shorts are ideal for gym sessions that support your training. The side splits, and stretchy fabric supports single-leg squats, lunges, and sled work alongside treadmill miles. Not to mention your runner's mobility work, too. They have a stretchier, more yoga-feel than race-style running shorts, which makes them more adaptable for functional training environments.

7. Best for Minimal, Lightweight Training: Sport Zero 5” Shorts
Best for: Light daily runs and warm-weather training.
Zero-feel with a mesh construction, these are the running shorts you wear to feel weightless. They have a 5” inseam for moderate coverage and a ventilated design to dry off sweat before you even know about it. Lighter in feel and modern in cut, the simplified build of these shorts means less fabric and weight, making them ideal for easy to moderate efforts when you don’t need to bring much with you.

8. Best for Layering & Race Day: Element Baselayer Half-Tight
Best for: Cold-weather layering, marathon training, and race day wear.
Half-tights, or compression shorts, are an essential addition to any serious runner's wardrobe. The close fit is perfect for base-layering during colder months and improved aerodynamics on race day. They can be worn alone or under your running shorts or joggers to provide extra warmth and compression, get your blood flowing, and reduce muscle fatigue. Oh, and did we mention how handy the pockets are? Having tight, deep pockets for longer distances when you're carrying multiple gels is so convenient. With breathable mesh panels, even when worn under layers, these shorts ensure optimal temperature regulation, making them ideal for long runs.

What to Actually Look Out For in Running Shorts
Breathability and Fabric
The best men’s running shorts are made from breathable fabrics that don’t weigh you down, allowing you to focus on the miles ahead. Think lightweight and sweat-wicking materials that dry faster and retain less sweat weight, reducing that ‘stuck to your legs’ feeling during long summer runs. For extra breathability, try shorts with side slits and mesh, or perforated panels.
Fit and Inseam Length
You want to try to find that perfect balance of a good length and functionality - shorts that give freedom of movement without being too loose or too tight. A stable, adjustable waistband prevents slipping or digging, especially when carrying small essentials that might otherwise drag you down. Look for flat seams around the waist and soft liner construction reduce irritation during repetitive movement.
For many, the best inseam length for running shorts is 5 inches, the sweet spot that offers good coverage and range of motion. For runners with thicker thighs, a 6-7” inseam combined with soft seam placement and slight fabric stretch often reduces friction more effectively than extremely short cuts.
Shorter length inseams are great for those who want maximum airflow or are already layering a pair of running tights underneath, while longer inseams suit those who prefer more thigh coverage.
Pocket Style
Pockets for essentials like your phone, keys, or gels can completely change the running experience. One of the biggest frustrations for runners is the constant shifting or bouncing of items during a run. Loose phones in side pockets or shallow shorts pockets can jostle with every stride, creating distraction, discomfort, and even chafing. That’s why the type, placement, and security of pockets actually matter.
Zip Pockets: Zip pockets become increasingly important as distance increases. These are ideal for items you want to be completely secure, such as phones, cards, or gels. A well-placed zip pocket keeps everything locked in place, even during sprints, trail runs, or high-impact intervals.
Hidden or Key Pockets: Many shorts include small internal pouches for keys or cash. These sit close to the body, reducing bounce and eliminating the need for separate armbands or belts. Great for hands-free, minimal runners.
Side or Mesh Pockets: Larger side or mesh pockets are convenient for gels or small items you may need mid-run. They’re more accessible but can bounce if not designed with stretch or elastic grips at the pocket openings.
Ultimately, the right pocket setup balances security and accessibility. A zip pocket may be overkill for a quick 5K, while a snug internal key pouch or stretch side pocket is perfect for daily runs. Choosing shorts with a thoughtful pocket design for your run-type reduces distractions, prevents mid-run adjustments, and keeps your focus entirely on your stride.
Lined vs Unlined
Built-in liners exist to manage moisture and reduce friction. Liners that are longer than the outer short length minimise inner-thigh chafing, prevent outer fabric bunching, and remove the need for additional underwear. For many runners, this simplifies decision-making, which can be helpful if you run often. They also help you stay comfortable for longer over long distances.
Compression liners provide added support, reduce muscle vibration, and increase coverage. They can be particularly useful for higher-intensity sessions or humid environments.
Linerless options may be preferable if you already wear compression shorts or prefer greater flexibility across sports. The key consideration is friction management, especially over longer distances, but thigh chafing can be remedied with other methods, like chafe balm.
Visibility for Low-Light Conditions
If you run at dawn, dusk, or after dark, visibility is not a bonus feature; it is protection. In low light, drivers do not register movement as quickly as you think, especially on high-congestion roads or poorly lit routes. Reflective detailing helps break up your silhouette and catch headlights from multiple angles, increasing the chance you’re seen earlier rather than later.
Look for reflective logos, trims, or piping on moving areas, such as the hem or side seams. As your legs move, those reflective hits create motion cues that stand out far more effectively than static fabric alone. If most of your training happens outside peak daylight hours, reflective elements move from a nice-to-have to a non-negotiable.
Versatility
For hybrid athletes or casual runners who want shorts you can wear beyond your runs, versatility is an important factor. Longer-length shorts are a style that transitions easily from workout gear to everyday gym wear without compromising performance.
Not every runner is training for a start line. Many are balancing lifting sessions, conditioning work, and everyday errands in the same pair of shorts. Versatility becomes valuable when you want shorts that you can wear beyond your runs.
Longer inseams and simpler silhouettes transition more naturally from treadmill to coffee run, and fabrics that stretch and maximise airflow will support your miles and lifts. Fewer wardrobe changes = more practicality. If your training week blends gym, road, and recovery days, choosing a versatile short saves both time and compromise.
How to Choose the Right Inseam Length
Inseam length is often the most decisive factor when selecting running shorts.
4” inseam → A 4” inseam provides maximum airflow and unrestricted stride freedom, making it ideal for race efforts and warm climates.
Style: retro, athletic look.
5” inseam → A 5” inseam represents the modern performance standard, balancing mobility and coverage.
Style: performance-driven, modern fit.
6” inseam → A 6” inseam offers slightly more coverage while maintaining strong versatility for daily mileage.
Style: hybrid, comfortable in between.
7” inseam → A 7” inseam provides traditional coverage and can improve confidence for newer runners.
Style: regular fit, beginner-friendly.
While shorter inseams may feel faster due to reduced fabric weight and interference, comfort and personal confidence ultimately matter more than aesthetics.
Running Shorts FAQ
Why do running shorts have liners?
Running shorts have liners to provide support and reduce chafing between the thighs, allowing for a more comfortable run without the need for additional undergarments like base layer shorts.
How do I prevent chafing when running?
To prevent chafing, look for running shorts with built-in liners or compression layers, apply anti-chafing balms or creams and ensure a proper fit to minimize friction.
Why are running shorts typically shorter in length?
Shorter-length shorts allow your legs to have a better range of motion, which can improve speed and stride length. They also minimize fabric resistance when running and improve air-flow which is ideal for improving performance and comfort during runs.
Why do running shorts have a split hem?
Running shorts often have a split hem to enhance mobility and reduce fabric restriction, making it easier to improve leg swing and take a longer stride, allowing you to move more freely.
How do keep your phone from bouncing during running?
Although zip pockets may work well for some, others find they experience their phone bouncing when running. Look for back pockets on running shorts as they tend to keep your phone more stable than side pockets. Alternatively, you could wear a running belt or an armband to keep your phone in place while running.
