Buying trainers: how to choose a pair that suits your needs

Buying trainers seems easy until you have to choose between adidas trainers, Puma trainers, Nike Dunk Low, New Balance trainers, Converse trainers and Vans Old Skool. A model may look appealing, but be less suitable for long working days, rainy bike rides or intensive exercise.

As a Joybuy Product Recommendation Officer, I filter product information based on practical features. So don’t just consider colour and brand. Pay particular attention to fit, materials, sole and the activity the shoe is designed for.

Three common pitfalls when buying trainers

1. Using a lifestyle model as a sports shoe

A casual shoe with a sporty look is not automatically suitable as a running shoe. Models such as the Nike Dunk Low, Converse trainers and Vans Old Skool are mainly designed for everyday use. They generally have a flat rubber sole and a classic fit, but not the same construction as running shoes.

For road running, cushioning, flexibility and a secure-fitting heel are more important. For unpaved paths, trail running shoes need grip, stability and protection.

2. Relying solely on your usual size

Sizes vary between brands and models. A size 42 trainer may correspond to a foot length of 27 cm in one model, while another shoe may use a different size guide. Always check the size chart and measure your foot in centimetres.

Measure both feet at the end of the day, wearing the socks you usually wear. With sports shoes, allow some room around the toes. A shoe that is too short will not become more comfortable by wearing it in for longer.

3. Ignoring materials and care

Suede, leather, canvas, mesh and synthetic textiles each require different treatment. Suede does not cope well with prolonged exposure to water. Mesh is often pleasantly breathable, but is not automatically waterproof. A rubber outsole can provide grip on many everyday surfaces, but that does not mean every sole is suitable for wet, muddy trails.

Also check whether the product information says the shoe is machine washable. For the models mentioned here, cleaning with a damp cloth and allowing them to dry naturally is usually recommended.

The key features to check

Fit and foot length

Pay attention to the stated fit, such as regular fit, and compare your foot length with the specific size chart. Laces make the fit more adjustable than a slip-on model. When walking or running, the heel should remain secure without creating pressure points.

Example: according to the product information, the adidas Barreda Decode has a regular fit. The size chart lists, among other options, EU 42 for a foot length of 25.9 cm and EU 42 2/3 for 26.3 cm. Use this information as a starting point rather than relying solely on your old shoe size.

Midsole and underfoot feel

The midsole partly determines how the shoe feels when you walk or run. For comfortable everyday trainers, a padded or cushioned midsole can be pleasant. Running shoes often specify a particular cushioning material in the product information.

According to the product description, the adidas Galaxy 7 uses a Cloudfoam midsole. This is a claim from adidas’ product information; underfoot feel is personal and depends on your weight, running style and the surface beneath you. The adidas Runfalcon 5 also lists Cloudfoam and an Ortholite insole.

Outsole, grip and intended use

Choose the sole based on your route:

  • Casual shoes: a flat rubber sole is suitable for everyday use in the city.
  • Running shoes: consider flexibility, weight and grip for tarmac or paved roads.
  • Walking shoes: look for heel stability, tread and protection.
  • Trail running shoes: a deeper tread, reinforced toe box and stability are practical on uneven paths.

The Salomon XA Pro 3D v9 GTX lists a Contagrip rubber outsole, a 3D Advanced Chassis and a GORE-TEX membrane. According to Salomon’s product information, these features are intended for trail running and walking. When using them in wet weather, also check the care instructions and the condition of the seams and fastening system.

Frequently asked questions about buying trainers

Which trainers are suitable for everyday use?

For everyday use, you can choose comfortable trainers with a lace fastening, regular fit and rubber outsole. The adidas Barreda Decode, New Balance trainers, Converse trainers and Vans Old Skool are examples of models with a casual look. However, check that the sole and cushioning are suitable for how much you walk and stand.

How do I determine the right trainer size 42?

Measure your foot in centimetres and compare the measurement with the size chart for the specific model. Also consider the fit and take the thickness of your socks into account. If you are between two sizes, the returns policy is important, but ordering based solely on the brand logo does not guarantee the right fit.

How long do trainers last?

Their lifespan depends on use, the surface, body weight, care and materials. Everyday trainers wear out more quickly when you also use them for running. Alternate between pairs, allow moisture to evaporate naturally and follow the care advice. Replace a pair when the sole becomes visibly smooth, the cushioning noticeably deteriorates or the shoe no longer feels stable.
