Types of Running Shoes

Running shoes are designed to help you run in a way that protects your leg and prevents injuries. They are also built to increase your athletic performance. There are different types with extra biomechanical features to improve specific athletic goals.

Here are a few below.

Lightweight Shoes

Lightweight shoes are built for speedwork and races. They are also called cross-country spikes or racing flats and are built to reduce the impact of the feet on the ground. These shoes have less cushioning and foam to create dynamic motion.

They are ideal for speed workouts like sprints, fartleks, HIIT, etc.

This may not be the best pair of shoes for beginners, as it offers less support and spring. People with specific foot and ankle support needs should consult an expert before buying lightweight shoes.

Motion Control Shoes

Motion control shoes or stability running shoes are built for specific pronation. Pronation is a natural body movement upon impact. It can be inward rolling (over pronation) or outward rolling (under pronation). These shoes provide extra support in the arch region, which helps to prevent the feet from overpronation.

These shoes are a great fit for plus-sized people as it provides stability and can bear more weight.

They have a wide sole to limit excessive motion and are less flexible than most sneakers.

Zero-drop Shoes

These shoes earn their name because they have no heel-to-toe height difference. Most shoes have a greater height off the ground at the heel than at the toe.

These shoes offer more mobility than traditional running shoes but provide less support.

Trail Shoes

Trail shoes are excellent for running on uneven ground. They have combined features of running and hiking shoes. Trail shoes offer great protection, durability, and support if you are training in muddy or rocky areas or a place with several road obstacles.

These durable shoes offer a better grip when running in softer or muddier terrains. They also protect the ankles from pebbles when running on rockier or rougher terrains.

Cushioned Shoes

Cushioned shoes have great cushioning and boost foam to reduce ground impact. In addition, cushioned or neutral shoes usually have outsoles and midsoles with shock dispersion features. This provides a layer of boost and a springy and plush feel.

These neutral running shoes are best for runners without detectable pronation as they offer little corrective or supportive elements that a person with pronounced pronation may need for a gait cycle.

Experts recommend them for supinators or under pronators.

Training Shoes

Training shoes are heavier running shoes and are best for training that doesn’t involve racing. So, a pair of training shoes is great for warming up if you are preparing for a half marathon or triathlon.

Road Running Shoes

These shoes are great for running on pavement or asphalt. The sole is made to grip asphalt or smooth surfaces, which is great for long-distance marathons.

How to Choose the Best Runnings Shoes

Jogger Tying Shoe

Choosing the best running shoe among dozens online or in a fitness store isn’t the easiest task. You have to consider several factors to pick the shoe that suits you.

Here are a few of those indispensable factors when getting a running shoe:


Getting your daily fitness run differs from preparing for a marathon, so the right shoe for both occasions is different.

You need to consider what’s more comfortable for both occasions. Long-distance running requires more cushioning to help the athlete feel comfortable.

Shoes with maximum cushion can feel like you are running on a cloud. But those without cushioning help you stay connected to the ground.

So, you should know which feels more comfortable for the distance you are running and factor it in when buying your running shoes.

Running Surface

Your running surface is where you’ll typically go for your runs. Traditional running shoes are great for pavement running, indoor surfaces, and even trails. They usually have flexible outsoles and are lightweight.

For example, the Adidas Adizero Boston 9 shoes are great for running on pavements.

If you mostly run on muddy or sticky trails, trail shoes offer a deep tread that’s great for uneven terrains.

You can invest in hybrid or mixed shoes if you like to run on different terrains. These versatile shoes have a balanced grip and cushioning that work well for pavement and mixed trails.

The outsole, midsole, and cushioning all contribute to what environment a running shoe works well in. The outsole is where the rubber and the road meet, providing stability by matching your footprint.

The midsole makes the shoe match your foot bends, so you must find one that suits how your feet flex and roll.

Lastly, the foot cushioning minimizes the impact shock of heel strikes.


Brand name is not the most important factor when buying your running shoes, as comfort and functionality trump brand name and trends.

If there’s a brand that’s well known for running shoes, you should check it out before others. For example, Adidas has several collections of running shoes.

All brands fit differently and use varying technologies and innovations to develop their running shoes. You should always consider comfort and fit.

Fit and Gait

There are different parts of a shoe, and each part contributes to its overall comfortability and performance, so you have to look at all these different parts when making your choice.

For instance, the ankle collar holds the heel down and cushions the ankle. Check how your ankle bones feel and whether your heels slip.

Some brands shape their ankle collar to support the ankle bone better, while others use extra pads to secure it. Either way, find one that fits right.

Many people don’t think of the saddle, but it plays a huge role in holding your running shoes in place. The saddle is the area around the foot arch between the ankle and the ball. A good saddle should hold your foot securely while allowing the arch’s natural doming as you run.

A shoe’s upper is another great point of consideration. Most shoe brands used to craft the upper with glued mesh and fabric. In recent times, brands now use 3D technology and knitting to create smoother and seamless finishing.

This can drastically alter the look of a pair of running shoes, so watch out for shoes that feel smooth and aren’t chaffing or bunching up anywhere.


This may seem obvious, but going for a show that’s your size will greatly improve your performance and comfort. Unfortunately, while the foot measuring device at your local fitness store can give you a pretty good estimate, it’s not always definite.

Sizing can be altered by materials and function. A shoe designed for treadmill running may be less snug than a trail shoe even when they are the same size.

ISO Standards regulate sizing in the shoe industry, but brands may still have slight variations that make all the difference when running. So, testing out your shoes is the only way to be sure it’s the fit you want.

Your running shoes are an investment, so test them before buying. If you buy them from a shop, you should ask to test them on a treadmill to see how they fit.

You should also note your feet type, whether you have flat feet, average arch sizes, or high arches, as this can help you make a better choice when shopping online.

Frequently Asked Questions

Can the same type of shoes fit differently?

Two pairs of the same-sized shoes can fit differently. While brands are careful about quality control, it’s still possible for two different shoes to fit the same.

For example, the same shoes with the same size and type specifications may be made from different factories of that brand. This means the shoes will pass through different hands and different machines.

So, it’s best to test out a pair of shoes to make sure it’s what you want before buying.

What does minimalist running mean?

Minimalist running preaches running with shoes with less supporting and corrective features or barefoot. Proponents of minimalist running claim that it helps a runner improve leg strength and health through a natural process.

They also say that running barefoot makes you run more carefully, which reduces accidents and injuries. They claim that while running barefoot, a person becomes more conscious, takes frequent but shorter steps, and lands softly.

This helps to reduce the chances of plantar fasciitis and other fractural injuries.

However, this is not widely accepted. There’s no scientific evidence to support barefoot running – instead, it can expose a runner to external injuries. For example, one can step on a pebble, sharp objects, or even stub a toe.

If you want to become a minimalist runner, it’s best to take it slowly. You can move from a shoe that provides more support to one with less support. You can also start running barefoot on even familiar trails for short-distance races.

When should I replace my running shoes?

Mileage is the main factor for determining if your running shoes need replacement. A good rule is replacing it once you hit 300-500 miles.

Where you run is also pretty important. For example, people who run on rougher trails may need to replace their shoes faster than people who do pavement or treadmill running.

Also, heavier runners may need replacement earlier than lighter runners. This is because heavier or plus-sized runners may bear more heavily on their shoes, causing them to wear faster.

You can write the date you got your shoes on the inside, and also note the mileage in your training log. This will help you know when you need newer running shoes.

Other obvious signs may require you to change your shoes. For instance, worn-out threads, uneven wear, and reduced shock absorption are all signs that you need newer shoes.

If you start to feel pain in your knees and joints when running, it may indicate that your shoes have lost cushioning.

Final Thoughts

Shoes are essential when running. Only a running shoe that meets all your comfort needs can produce your best performance. The Adidas Boston 9 is a great shoe for fast-paced marathons. However, you still have to consider your specific needs to determine if it suits you.
