What Shorts Are Best For Running?

Whether you’re just starting your running journey or training for an ultra marathon, the right pair of shorts can make all the difference. Running shorts aren’t just about looking good – they’re a key part of any running outfit, designed to enhance your running performance.

Getting the right pair of shorts is just as important as choosing a pair of running shoes. But how to choose running shorts? The ‘best running shorts’ really comes down to personal preference – but there are a few things to look out for which are sure to enhance your experience, from preventing chafing to keeping you cool. Let’s take a look at everything you need to know about selecting running shorts, so you can choose a pair that work for you.

What to Look For

When it comes to picking out the perfect pair of shorts, there are a few key factors to consider. From breathability to durability, these features will help you to choose shorts that minimize distractions and allow you to focus on putting one foot in front of the other.

Breathability

Different styles of shorts offer different levels of breathability. Some styles of shorts are looser, featuring split hems or slip slits that create airflow around your legs to keep you cool as you run. Others have a tighter compression-style design, which doesn't allow air to circulate around your legs as much. The choice of style is yours – just make sure that whichever style you go for is made from breathable fabric.

Many premium running shorts also have features to maximize cooling and comfort, including mesh panels and perforated or laser-cut designs, with tiny holes to allow heat to escape.

Comfort

There’s nothing worse than shorts that don’t fit quite right, meaning you’re constantly pulling them down or adjusting the waistband as you run. Ideally, your running shorts should feel like a second skin – they should be so comfortable that you barely notice you’re wearing them.

That means looking out for features like:

• Minimal seams, or flat seams that minimize chafing

• A waistband that doesn’t dig in

• Adjustable waistband so you can get the right fit for you

• A comfortable liner

When trying on shorts, perform a few running movements to ensure nothing pinches, rides up, or restricts your natural stride. 

Length

There are various lengths of running shorts out there, and it really comes down to personal preference – you might also find that you like to wear different lengths for different types of running:

• Shorter shorts (3 inches) offer freedom of movement and plenty of airflow, making them ideal for speedwork and racing. Our 3” shorts are particularly popular among advanced runners looking for minimal restriction and high performance. They’re also the best running shorts for hot weather. 

• Mid-length shorts (5 inches) offer a balance of coverage and mobility, and are suitable for most training runs, whatever the weather. 

• Longer shorts (7+ inches) offer more coverage, making them great both for cooler conditions and added sun protection. They’re also popular among trail runners looking for more protection from scratchy brambles, thorny gorse bushes, stinging nettles, and low-hanging branches.

You can also choose 2-in-1 shorts that offer the best of both worlds, with a longer built-in pair of liner shorts for added coverage, and the lightweight comfort of traditional running shorts on top.

Fabric Type

Shorts that are made from a breathable fabric are non-negotiable. Avoid materials like cotton as these will simply soak up sweat and moisture, which can make for an uncomfortable work out. Look for shorts that are made from lightweight, moisture-wicking fabrics like polyester and nylon. They’re designed to pull moisture away from your skin, allowing it to evaporate quickly. This keeps you dry and comfortable, even during the hardest speed sessions. Plus, they’re lightweight and quick-drying, and maintain their performance qualities even after you’ve washed them countless times.

Features

The right features can transform a good pair of running shorts into a great one. Look out for features like:

• Pockets: What do you need to carry when you’re running? Will you just be taking your house key with you, or do you need pockets to stash your gels? Whichever style of shorts you choose, the pockets should fit what you need with minimal bouncing as move.

• Waistband: Look for an elastic waistband that can be adjusted to get the perfect fit. Wider waistbands are also typically more comfortable and less likely to dig in or chafe.

• Lightweight: Every ounce counts, particularly when you’re aiming for a PR, so look out for lightweight material that feels weightless and comfortable. This will also help to keep you cool when you’re running on hot days.

• Reflective elements: Reflective elements can help you to be seen on early morning or evening runs.

• Liners: Do you want shorts with built-in underwear? Or would you prefer the freedom to choose your own? It’s completely up to you, so choose shorts that fit your style.

Durability

Quality running shorts should withstand hundreds of miles of running and washing without losing their shape, elasticity, or technical properties. Look out for quality fabric and elastics that retain their stretch, fade-resistant fabrics and reinforced stitching at stress points as indicators that your shorts will stand the test of time. 

The best quality running shorts require a higher upfront investment, but they’ll typically pay for themselves when you consider cost-per-wear over time compared to cheaper alternatives that might need to be replaced more often.

How to Choose the Right Size Shorts?

Finding the perfect fit for your running shorts is crucial for comfort and performance. Too tight, and they'll restrict movement and cause chafing; too loose, and they might bunch up or create unnecessary friction. Sizing can vary between brands, so always check size charts when purchasing to make sure you get the right fit. 

Men's Running Short Sizing

You’ll want a comfortable fit around the waist and hips, with adequate room for movement through the legs. To get the right waist measurement, use a flexible tape measure around your natural waistline (just above the hip bones) while standing relaxed. 

When it comes to length,  it’s key to remember that if you’re tall, you may need a longer inseam for more leg coverage, while shorter runners might want to go for 3-5 inch shorts.

Women's Running Short Sizing

For women, you’ll want to measure both your natural waist and your hips (at the fullest part). You’ll also need to consider your preferred length, but this shouldn’t affect the fit of your shorts. 

You might want to practice a few movements when trying on your shorts, like walking lunges and squats, to make sure that the waistband stays in place without rolling and that the shorts don’t ride up too much when moving.

Shorts vs Tights? 

Whether you choose to wear shorts or tights, the weather will likely influence your decision. 

Shorts are ideal for warm weather and high-intensity workouts, where you need maximum ventilation. Shorts also allow for unrestricted freedom of movement and they typically weigh less than tights, which can make all the difference when you’re racing for a personal best.

Tights offer several benefits too, including:

• Weather protection: The longer length provides warmth in cold conditions while still wicking sweat away from your skin.

• Chafing prevention: The snug fit can eliminate friction between your thighs that can cause painful chafing (although 2-in-1 shorts also offer this as the best running shorts to stop chafing ).

• Trail protection: For off-road runners, tights offer an additional defensive layer against scratches from branches, protection from poison ivy, thorny bushes, and ticks.

• Muscle support: Some running tights offer compression benefits that may help to reduce muscle fatigue.

The decision often comes to temperature, with many runners opting for tights throughout the colder months and switching to shorts as the weather warms up. Want to find out more about running tights? Learn how to wear them, with tips on choosing the right size and features to look out for.

Best Shorts for Endurance Running

When logging serious miles for marathon or ultra events, it’s crucial that your shorts can go the distance. Look out for flat seams to eliminate friction points and minimal seams to reduce potential chafing.

You may also need more storage in your shorts for longer runs, so choose a pair with multiple secure pockets for your keys, phone and fuel. 

Best Shorts for Everyday Training

You’ll probably put a lot of miles into your daily training shorts, so they need to be versatile and durable. Shorts with a mid-length seam are a good option, for a balance of coverage and freedom of movement that works in most weather conditions and for any type of training from track sessions to steady runs.
