How to Choose the Best Trail-Running Shoes: Stability, Cushioning and Comfort

There's not much that beats the exhilaration and freedom you experience when you hit the trails for a run. Trail running challenges you physically and mentally, but it also offers a unique sensory experience that forces you to take your running game to the next level. You look for, listen to and feel changes in your surroundings that require you to respond quickly and adapt.

But these challenges also increase your risk of injury. So, it's important to train wisely and equip yourself with essential trail-running gear and footwear for your off-road adventures. Get a head start by choosing a pair of stable trail-running shoes.

• Trail-running shoes differ from road-running shoes.
• Trail-running shoes should prioritise stability, traction and fit to provide support on uneven terrain.
• Stable trail-running shoes help reduce ankle roll and lower-limb injury risk.
• Traction lugs, rock plates and supportive cushioning improve control on trails.

Trail running can help improve your overall running performance. In fact, running in a constantly changing and unfamiliar environment can force you to adapt your posture, gait and leg stiffness. These biomechanical adaptations help you become a more responsive and efficient runner on the road and on the trails.

But the benefits don't end there. When you run off-road, your maximal speed generally decreases while your effort increases. Research published in the Journal of Experimental Biology found that running on rough trails requires 5% greater metabolic energy expenditure than running on smooth, hard surfaces. Researchers theorise that at least half of the increased workload is due to the mechanical work required to go up and over challenging surfaces.

Aside from physical benefits, there are also mental benefits. Study after study has linked running on trails with improved mental well-being. In fact, a 2019 research review suggested off-road running as an effective strategy for managing the pressures of urban life. And a review published in Extreme Physiology and Medicine suggests that exercising outdoors may reduce stress and mental fatigue and improve mood and self-esteem.

Trail running does pose safety risks. Unstable surfaces that provide a challenge also increase your chance of injury. One 2021 study found that a quarter of all trail runners reported at least one running-related injury in the 12 months leading up to a popular trail-running race. The injuries primarily affected the lower limbs, specifically the knee, ankle and foot. Joint sprains, tendinopathy and muscle injuries were some of the most common amongst trail runners in the study.

So how do you reap the benefits of trail running without falling victim to the additional safety risks? Researchers have observed that running shoe choice can play a role in running economy and biomechanical stability. One of the smartest investments may be a trail-running shoe with some stability features.

Stability trail-running shoes are different from stability road-running shoes. Stability in trail-running shoes focuses on controlling foot and ankle movement on uneven ground, not correcting overpronation like many road stability shoes.

Stability road shoes help those who overpronate by supporting the foot's arch and providing greater support through the midsole that may also extend into the heel. If you run in a stability shoe on the road, you'll still look for stability features in a trail shoe.

Even those who run in neutral shoes on the road will want to consider stability when selecting trail shoes. Stability trail-running shoes may not only help prevent you from rolling your ankle on uneven terrain, but they also provide other safety and technical features to help you tackle the trails.

Stability is a must for trail-running shoes, but what else should you look for in a pair? There are several features that a well-designed trail-running shoe can provide to promote safety and better lower-body mechanics:

• Rugged traction will help you master rocky surfaces, slick mud or any terrain that you encounter.
• Durable protection from unexpected changes in weather, rough landscapes and debris.
• Stiff and cushioned shoes will keep your foot secure and your ankle in alignment.

Here's a closer look at some of the features to consider when shopping for trail-running shoes.

When shopping for a good trail-running shoe, you'll want to flip the shoe over and inspect the outsole. The tread patterns on the bottom of the shoe, also called traction lugs, are designed to keep you stable on any terrain you may encounter on the trails.

Multidirectional lugs improve braking on descents, while wider lug spacing helps shed mud on soft trails.

The soles should also be tough enough to protect your feet from jagged rocks or tree stumps. However, you don't want a shoe with a sole that is too heavy to be versatile.

Instead, try to find a shoe that will provide a lightweight grip for a smooth ride between trails and the road.

You want your shoe to protect your feet from low-lying branches, rocks and other debris. Look for features like an ankle gaiter or ankle collar to hug your foot and keep dirt and debris out. Extra skin around the toe can also deliver foot protection by preventing stubbing or injury. And a segmented rock plate, which sits between the midsole and outsole, provides protection from rugged terrain while maintaining flexibility.

While good trail-running shoes provide protection, you don't want them to feel like a hiking boot. For breathability and ventilation, look for mesh on the upper.

A trail shoe often has more of a snug fit than a road shoe. You don't want the shoe so tight that the foot feels compressed, but with the extra multidirectional movement during a trail run, you want to minimise rubbing in the shoe to prevent slippage and blisters. There are a few technical features that can help.

• A heel cup or heel cushioning can keep the foot secure.
• A secure midfoot band system, like in the Nike Juniper Trail, can provide stability as you tackle uneven paths. The sock-like band wraps around your foot to help keep it stable.
• Foam from heel to toe can provide responsive and stable cushioning for comfort and smooth transitions on rocky terrain.

The socks you wear also make a difference in how the shoes fit. Many trail runners wear thicker socks than they would wear for a run on the road, so you'll want to try shoes on with the socks you're planning on using.

Now, what makes a good trail-running sock? Often made from wool-blend fabric, the socks should be woven to provide grip within the shoe to keep your foot in place, but they should also be breathable and moisture-wicking. To avoid scrapes and abrasions, the sock should cover your ankles and at least part of your calf.

It's also a good idea to choose socks with compression for long-lasting comfort during endurance runs.

Your shoe's offset is the difference between the base height at the heel and the base height at the toe or forefoot. It is often related to the amount of cushioning in the shoe. Shoes with more cushioning usually have a greater offset, or heel-to-toe drop.

The offset of your trail-running shoe should be similar to the offset of your road-running shoe. Why does this matter? Some trail running enthusiasts prefer a low or very low drop to feel closer to the earth. These minimalist shoes usually have an offset of less than 4 millimetres, and they encourage you to strike the ground at the midfoot or forefoot.

On the other hand, many road shoes have a moderate or maximal drop and encourage you to strike the pavement at the heel. One type of shoe is not necessarily better than the other, but quickly switching from one to the other can cause abrupt biomechanical changes that can lead to pain or injury.

Muddy trails, rocky paths and steep descents each require different stability features, from aggressive lugs to stiffer midsoles.

Outsoles with deep lugs are beneficial for muddy or wet terrain, while shorter lugs can suffice for dry, packed surfaces. If you're tackling hills, multidimensional lugs will help on descents.

For rocky terrain, you might want a shoe with a stiffer midsole to help protect your foot. The Nike Kiger 10 has a rock shield in the forefoot which provides additional protection between your foot and debris.

While trail running can be unpredictable, the right trail-running shoe balances stability, traction and comfort for the terrain you run on most often.

For mild terrain, from road to trail, the Nike Pegasus Trail-Running Shoes should suffice. But for more technical trails that involve steep hills, mud or rocks, you'll want to consider a shoe with more traction like the Nike Zegama 2, which has an ankle gaiter. This shoe offers maximum cushioning along with a diverse, rugged lug pattern for increased grip.
