Choosing trainers and running shoes: a practical guide to style, comfort and use

Ordering a new pair of trainers and running shoes seems simple. However, choosing the wrong size, an unsuitable sole and marketing claims often lead to disappointing purchases. A casual trainer is not automatically suitable for running, and a running shoe will not feel comfortable for everyone.

Joybuy Product Recommendation Officer therefore focuses primarily on verifiable information: materials, sole construction, fit and intended use. This makes it easier to compare Nike trainers, adidas trainers, New Balance trainers, Puma trainers and Skechers trainers fairly.

Three common pitfalls when choosing trainers and running shoes

1. A well-known brand name is not enough

Nike, adidas, New Balance, Puma and Skechers offer models for different purposes. A retro trainer with a sturdy rubber sole is mainly designed for everyday wear. A running shoe usually has a lighter construction, a foam midsole and an upper designed to improve ventilation.

So do not just look at the logo. Check the product details as well. For example, the Nike Dunk Low is a casual trainer with a leather upper and rubber outsole. This makes it an interesting option for everyday wear, but not automatically suitable for longer running sessions.

2. ‘Comfortable’ is not a fixed technical standard

Words such as comfortable, responsive or supportive are often part of a product description. According to the brand’s own product information, a particular foam or cushioning technology may contribute to a certain ride feel. That does not guarantee that every wearer will experience it in the same way.

Instead, look for specific features:

  • midsole type, such as EVA, Cloudfoam, Dreamstrike or ABZORB;
  • upper material;
  • flexibility and weight;
  • width and fastening;
  • outsole tread.

3. The same EU size may fit differently from one model to another

A size 40, 42 or 44 is a useful starting point, but it does not guarantee a perfect fit. Brands use different size charts, and models may feel narrower or roomier. Always check the foot length in centimetres when it is provided.

For example, the product information for the adidas Run 70s 2.0 in size 40 gives a foot length of 25.5 cm. For the Puma Speedcat OG, a foot length of 27 cm is given for EU 42. Use these details for comparison, not as a substitute for the official size chart for your chosen model.

Which specifications should you check?

Upper: ventilation versus support

A mesh upper generally allows more air to pass through than smooth leather or synthetic leather. This can be useful for walking, everyday wear or sports. Mesh is more susceptible to dirt, however, and often needs to be cleaned with a soft brush or damp cloth.

Leather and synthetic overlays often create a more enclosed, sturdy construction. According to the product information, Nike Wmns Dunk Low models use leather and textile, with a padded collar and a cushioned inner. This suits casual wear and outfits where appearance is important.

Midsole: consider the shoe’s purpose

The midsole affects how the shoe feels while walking or running. Models with Cloudfoam or Dreamstrike, for example, are available for light training and short distances. According to the product specifications, the adidas Galaxy 7 M uses a Cloudfoam midsole and is intended for road running.

For everyday walking or standing for long periods, a shoe with noticeable cushioning can feel comfortable. For trail running, stability and grip are also important. The Salomon DRX DEFY GRVL lists Active Chassis, Energy Foam and an All Terrain Contagrip outsole. According to the product description, this model is designed for gravel paths, mixed terrain and outdoor activities.

Outsole: urban use is different from trail running

A flatter rubber tread often works well on paved surfaces. For woodland paths, mud or loose stones, you need a more aggressive tread. Also consider the sole construction: a trail model may feel heavier and stiffer on tarmac.

A men’s running shoe or women’s running shoe does not need to be selected solely by gender. Fit, foot length, width and personal use are more important than the label in the product name.

Frequently asked questions

Are trainers suitable for running?

Some sports shoes are suitable for short, easy runs, but casual trainers are not automatically designed for this purpose. Check the midsole, weight, flexibility and the running surface the model is intended for.

How do I choose between men’s and women’s running shoes?

Start with foot length, width and the fit you want. The men’s or women’s designation can help you filter models, but always check the specific size chart and product measurements. This also applies to size 40 trainers, size 42 trainers and size 44 trainers.

When should I replace my running shoes?

There is no universal mileage figure that applies to everyone. Look for visibly worn tread, permanent deformation of the midsole, parts coming loose or a noticeable change in the way the shoe feels when you walk or run. With daily use, shoes may wear out faster than when used for occasional walking.
