Choosing running shoes without making the wrong purchase: how to find the right pair

A new pair of running shoes can seem like a quick choice online. However, small differences in fit, sole and intended use can have a major impact on comfort. A shoe designed for asphalt is not automatically suitable for muddy woodland paths. Likewise, a lightweight model with plenty of cushioning will not suit every runner.

As a Joybuy Product Recommendation Officer, I filter product information based on practical considerations. This helps you see which features can be checked and which marketing terms should not be assessed separately from the specifications.

Common pitfalls when choosing running shoes

1. Using one pair of running shoes for every type of terrain

Road running shoes generally have a sole designed for asphalt, cycle paths and paved routes. On loose ground or wet roots, grip may be more limited. For trail running, a deeper tread and more hard-wearing outsole are more relevant.

A road and trail model can be practical if your route varies, but always check the sole construction and intended use.

2. Looking only at weight or cushioning

Lightweight running shoes often feel flexible while running, but low weight does not automatically indicate stability or durability. Conversely, a shoe with a thicker midsole may be comfortable for steady distances but feel less responsive during speed training.

Therefore, consider the combination of weight, midsole material, fit and outsole. According to adidas product information, for example, the Adizero Boston 13 features Lightstrike Pro, ENERGYRODS and a Lighttraxion outsole. These are specific components; terms such as “faster” or “more efficient” remain dependent on the individual wearer and how the shoes are used.

3. Ordering the wrong size

An EU size is not exactly the same across every brand. Check your foot length in centimetres or millimetres and compare it with the size chart for the specific model. A regular fit also does not necessarily mean that the shoe is suitable for a narrow or wide foot.

In sports shoes from sizes 39 to 44, you will find many variations, including half sizes such as 39 1/3 and 41 1/3. Measure both feet, preferably at the end of the day, and leave some room around the toes.

Key specifications explained

Intended use: road, trail or everyday wear

First, decide where you will mainly wear the shoes:

  • Road running: a flatter tread, flexible sole and comfortable midsole are practical.
  • Trail running shoes: look for a sole with more pronounced tread, a protective toe box and an upper that can better withstand dirt and wear.
  • Gravel and mixed terrain: a combination of stability, grip and a breathable upper may be suitable.
  • Everyday use: as well as comfort, consider maintenance, the fastening system and the sturdiness of the sole.

Women’s running shoes and men’s running shoes differ in more than just colour. Fit, last and available sizes can vary between models. Unisex running shoes are useful when the size chart and foot shape are a good match.

Midsole and cushioning

With cushioned running shoes, the midsole material is particularly relevant. EVA and variants such as Cloudfoam are designed to absorb shock and provide comfort. This does not mean that every shoe is suitable for every distance or running style.

The adidas Runfalcon 5 lists a Cloudfoam midsole and an Adiwear outsole. According to the product information, the adidas Galaxy 7 also uses Cloudfoam, with a TPU outsole. These models are therefore logical options to consider for steady runs and everyday use, but check the size and your personal preferences before ordering.

Upper, ventilation and protection

A mesh upper generally provides air circulation. Breathable running shoes can be comfortable in warmer weather or during longer training sessions. However, mesh is not the same as waterproofing. For rainy walks or wet trails, a membrane such as GORE-TEX, found in certain Salomon models, is a more specific feature to look for.

Waterproof trail shoes keep moisture out more effectively, but may feel less airy than open mesh. So do not automatically choose waterproof shoes if you mainly run on asphalt in dry weather.

Grip and stability

When checking running shoes with good grip, look at the type of rubber and the tread pattern. A flat rubber sole is more suited to paved surfaces, while a deeper tread is more practical on mud, gravel and uneven paths.

Stable running shoes may feature additional structure in the sole or upper. The Salomon XA Pro 3D v9 GTX lists a 3D Advanced Chassis and Contagrip outsole. According to Salomon product information, these components are intended to provide support and grip on technical terrain. Treat this as product information, not a guarantee of a particular running performance.

Recommended models by user profile

Suitable for: Budget-conscious beginners
adidas Runfalcon 5 size 42 2/3

adidas Runfalcon 5 BETSCA/FTWWHT/CBLACK size 42 2/3

Why it suits this profile: According to the product information, this model is designed for everyday running and distances of 0–10 km. The lace fastening allows you to adjust the fit.

How this product avoids the pitfall

The specifications mention mesh, Cloudfoam and Adiwear rather than relying only on general comfort claims. However, check the stated foot length and EU size.

Key benefit & advantages

Breathable mesh upper, Cloudfoam midsole and Adiwear outsole according to adidas.

Suitable for: Buyers looking for premium quality
Salomon XA Pro 3D v9 GTX

Salomon XA Pro 3D v9 GTX 472701 size 41 1/3

Why it suits this profile: This model is intended for trail running and walking on rougher terrain, with a GORE-TEX membrane and Quicklace system according to the product description.

How this product avoids the pitfall

Choosing a trail model prevents you from using a flat road sole on wet or uneven paths. Waterproofing comes at the expense of maximum ventilation.

Key benefit & advantages

GORE-TEX membrane, 3D Advanced Chassis and Contagrip sole according to Salomon.

Suitable for: Specific uses & intensive users
adidas Adizero Boston 13

adidas Adizero Boston 13 M size 39 1/3

Why it suits this profile: The product information positions this model for intensive training and race preparation. The textile upper is designed to provide ventilation.

How this product avoids the pitfall

The model is not presented as a universal walking shoe, but as a running shoe for speed training. This means its intended use is better matched to its construction.

Key benefit & advantages

Lightstrike Pro, ENERGYRODS, breathable textile and Continental Rubber are listed in the product specifications.

Maintenance and lifespan

The lifespan of running shoes depends on the surface, how often you run, body weight, storage and materials. Check regularly for:

  • wear on the tread;
  • cracks or parts coming away from the midsole;
  • an upper that no longer fits securely;
  • a fit that has become noticeably less comfortable.

Clean shoes according to the label or product instructions. For several models, adidas recommends wiping them with a damp cloth and allowing them to air-dry. PELLIOT specifies hand washing with mild soap and cold water for certain models. Do not use a tumble dryer or direct heat unless this is permitted.

Frequently asked questions about running shoes

How long do running shoes last?

There is no fixed timeframe. Pay particular attention to wear and changes in fit and cushioning. Someone who often runs on asphalt may put more strain on the sole than someone who alternates between soft paths.

Are running shoes suitable for walking?

Many road models can be used perfectly well for everyday walking. For wet woodland, gravel and mud, trail running shoes with a lugged sole are generally more practical. A football boot or lacrosse shoe, such as the Nike Huarache 9 Varsity Lax FG, is not intended as a general-purpose running shoe because of its studded construction.

How do I determine the right size?

Measure both feet in centimetres or millimetres and compare the longer foot with the brand’s size chart. With women’s running shoes, men’s running shoes and unisex models, also pay attention to width. Fit information such as “regular” is an indication, not a substitute for the specific size chart.
