Buying trainers without buyer’s remorse: how to choose a pair that suits you

When buying trainers online, people often look at colour, brand and price first. That makes sense, but it is not always enough. A shoe may look appealing and still be less suitable for long walks, running or intensive sport. A few practical checks can help you avoid having to start your search again after a short time.

Three common pitfalls when buying trainers

1. Using lifestyle trainers for sport

Lifestyle trainers are designed for everyday wear and casual outfits. That does not automatically mean the model is suitable for running, basketball or another high-intensity sport. Check the stated intended use, sole construction and level of cushioning.

A low rubber cupsole, for example, works well with a classic urban style, as seen on certain Converse Star Player 76 models. For running, a breathable upper, suitable midsole and flexible outsole are usually more important.

2. Looking only at the EU size

An EU size is not exactly the same for every brand or model. Width, fit and material also affect how a shoe feels. A leather upper may feel different from mesh, while a structured heel leaves less room when putting the shoe on.

Always check:

  • the foot length in centimetres, if provided;
  • the size chart for the specific model;
  • whether the shoe fits true to size, narrowly or generously;
  • the space around the toes and the fit around the heel.

If you are looking for trainers in sizes 36 to 46, it is best not to filter only by the available size range. Check the specific sizing information for each product as well.

3. Confusing marketing language with product specifications

Terms such as “dynamic”, “performance” or “extra comfort” do not tell you much without technical details. Instead, look for verifiable information: upper material, sole type, fastening, size, weight where available and recommended use.

A brand’s own research may suggest that a particular technology has a specific effect. When choosing what to buy, it is wiser to treat that claim as brand information and also look at the actual product description and experiences during the intended use.

Which specifications deserve attention?

Upper and lining

Leather and synthetic leather are generally more structured and suit a robust, classic look. Textile and mesh usually allow more airflow and may feel more comfortable during active use. The lining affects the wearing experience, especially when you wear the shoes for longer periods.

The adidas Barreda Decode, for example, combines suede or mesh textile with synthetic materials, depending on the version. A Converse Star Player 76 has a canvas upper and a low-profile shape. This makes the model visually versatile, but its construction differs from that of adidas running shoes.

Midsole and sockliner

The midsole largely determines how the shoe feels underfoot. Cushioning materials are often highlighted for women’s and men’s running shoes. The adidas Runfalcon 5, for example, lists a Cloudfoam midsole and an OrthoLite sockliner in its product information.

For everyday wear, a padded collar or cushioned sockliner may be enough. For longer running sessions, it is more important that the model is specifically offered for running. A casual trainer is not automatically a substitute for a running shoe.

Outsole and grip

Look at the outsole material and shape. Rubber is widely used for its durability and grip. A pivot point, as found on various Nike Dunk Low models, is part of the classic sole construction. For basketball shoes, tread, stability and freedom of movement on court may be more important.

Wrestling requires even more specific guidance: according to the product information, Nike wrestling shoes such as the Inflict 3 are designed for use on the mat. Do not use this type of model on rough outdoor surfaces. For basketball, you can browse the options in the category original basketball trainers.

Frequently asked questions about buying trainers

How do I find the right size when buying trainers online?

Measure both feet at the end of the day, as their length can vary slightly by then. Compare the longer foot with the model’s size chart. For adidas, for example, check the stated foot length in centimetres rather than looking only at EU 40, 42 or 44. Also check whether the shoe has a regular or performance fit.

How long do trainers last on average?

Lifespan depends on usage, surface, body weight, care and materials. Everyday lifestyle trainers wear differently from adidas running shoes or basketball shoes. Replace a pair when the sole becomes visibly smooth, the heel no longer provides support or the upper starts to come away. According to the product listings, the models mentioned are covered by the EU statutory guarantee of at least two years; additional rights may apply.

Can you wear sports shoes as everyday trainers?

Sometimes, but it depends on the model. Running shoes may be suitable for walking and everyday use, while Nike wrestling shoes are specifically made for mats. Basketball shoes often have a different sole and fit from lifestyle trainers. So choose the intended use first, followed by colour, brand and price.
