Buying shoes and trainers: how to choose a pair that suits the way you use them

Buying shoes and trainers online seems straightforward until you have to choose from hundreds of models. A low price, well-known brand or striking colour says little about the fit or whether a shoe is suitable for your everyday needs. If you focus only on looks, you could end up with shoes that pinch, wear out quickly or provide insufficient grip.

As a Joybuy Product Recommendation Officer, I mainly filter products by verifiable information: materials, fastening, sole, fit and intended use. This helps ensure that marketing language does not make the decision for you.

Three common pitfalls when buying shoes online

1. Using a trendy model for the wrong activity

A lifestyle model such as the Nike Dunk Low, Vans Old Skool or PUMA Speedcat can work well with a casual outfit. That does not automatically mean it is suitable for running, long walks or trails. A flat rubber sole and low-profile construction provide different support from a running or walking shoe.

2. Looking only at the EU size

A size 42 does not have the same internal length or width across every brand. Women’s trainers and men’s trainers may also fit differently. Always check the size chart, foot length in centimetres and information such as “regular fit”, “slim” or a wide toe box. Extra care is important with children’s shoes because children’s feet grow, and a shoe that is too tight can quickly become uncomfortable.

3. Confusing material claims with complete protection

Leather, mesh and synthetic materials each have their own properties. A leather trainer is not automatically waterproof. Likewise, a model with a water-repellent finish is not the same as a shoe with a waterproof membrane. Always check the product description and care instructions. According to Salomon’s product information, the XA Pro 3D v9 GTX has a GORE-TEX membrane; for precise information about protection and care, follow the manufacturer’s guidance.

The key specifications to check

Fit and size

Measure your foot at the end of the day, when your feet generally take up slightly more space. Place your heel against a wall and measure to the tip of your longest toe. Compare this measurement with the product’s size chart. Also pay attention to:

  • Toe room: your toes should not press against the front.
  • Heel hold: your heel should remain stable without painful pressure.
  • Width: a standard model is not always suitable for a wide foot.
  • Socks: try on running shoes with the socks you wear while exercising.

For example, the PELLIOT models in this selection specify different fits for narrower and standard or wider feet. That is more useful than simply seeing the label “unisex”.

Sole and intended surface

The sole largely determines where you can use a shoe safely and comfortably.

  • Everyday use: a flat rubber sole generally works well on streets and indoors.
  • Running: look for cushioning, low weight, flexibility and a sole suited to asphalt.
  • Trail running: look for a lugged sole with grip on mud, rocks and loose ground.
  • Walking: stability, heel protection and grip are often more important than very low weight.
  • Football or lacrosse: studs should be suited to the surface. According to the product description, the Nike Huarache 9 Varsity Lax FG is designed for firm ground and has an FG stud configuration.

An outdoor sole is not automatically comfortable on smooth shop floors, while a smooth lifestyle sole offers little traction on wet paths.

Upper, lining and care

Mesh generally allows more air to circulate than leather, while leather can provide a more substantial feel and requires appropriate care. Check whether the upper is made from leather, textile, mesh or synthetic material. Also look at:

  • the lining, particularly for prolonged wear;
  • the fastening, such as laces, hook-and-loop or Quicklace;
  • the care method;
  • whether the toe and heel are reinforced;
  • the statutory guarantee and returns policy for online purchases.

Do not use a washing machine if the product information specifies hand cleaning. This could damage the shape, adhesive bonds and materials.

Frequently asked questions about buying shoes and trainers

How do I determine the right shoe size when ordering online?

Measure both feet in centimetres and use the size chart for the specific model. Choose the size that fits your longer foot and consider how you will use the shoes: sports socks sometimes require a little more room. Also check the returns policy before placing your order.

How long do trainers and sports shoes last?

Their lifespan depends on the materials, how they are used, the surface and maintenance. Everyday trainers can wear out more quickly if you also use them for sport. Check the sole for smooth patches, cracks and reduced grip. With running shoes, cushioning and sole wear are particularly important signs that it is time for a replacement.

Are waterproof shoes suitable for everyday use?

They can be, but a waterproof membrane may allow less air to pass through than open mesh. That protection can be practical for rainy walks or outdoor activities. For warm days or use exclusively indoors, lightweight, breathable shoes may be more suitable. Use the model for the purpose its construction is designed for.
