Choosing trainers and shoes: a practical guide to size, materials and everyday comfort

Buying trainers and shoes online seems straightforward, until a pair turns out to be too narrow, wears out quickly or is unsuitable for the way you intend to use it. Product photos also do not always show how a sole feels, how much room there is in the toe box or how the shoes should be cared for. With these checks, you can compare women's trainers, men's trainers, children's trainers, casual shoes and sports shoes based on specific features rather than marketing language.

Common pitfalls when buying shoes

1. Confusing a well-known brand name with the right fit

Nike Dunk Low, Vans trainers, Skechers trainers, Converse trainers and Puma trainers each have their own design. That does not mean every model fits in the same way. A low canvas trainer can feel very different from a shoe made with mesh, thick padding or a wider last.

Always check:

  • the stated fit, such as normal or regular fit;
  • the shoe width, for example D, G or standard;
  • the size guide and any foot-length measurement in centimetres;
  • whether the insole can be removed.

A model that fits true to size may still be unsuitable for a wide foot or a high instep.

2. Focusing only on colour and silhouette

A white trainer, black trainer or eye-catching model may work well with your clothes, but the material also affects how much care the shoes need. Leather, synthetic leather, suede, canvas and mesh all react differently to rain, dirt and everyday wear.

Pay attention to the product details:

  • upper: for example, textile, mesh, synthetic leather or suede;
  • lining: textile can feel different from a padded interior;
  • sole material: rubber offers different flexibility and grip from EVA;
  • fastening: laces are adjustable, while hook-and-loop fastenings are practical for children.

3. Reading “comfortable” without checking the construction

Comfort is personal. A product description may mention a padded collar, cushioned insole or Memory Foam insole, but that does not guarantee that the shoe will feel comfortable for every wearer. Look for checkable features such as the insole thickness, sole type and available size.

A secure fastening is particularly practical for children's shoes. For sports shoes, flexibility, grip and a good fit matter more than appearance alone.

The key specifications to compare

Size and width

Measure both feet at the end of the day while wearing the socks you normally use. Place your heel against a wall and measure to your longest toe. Then use the size guide for the specific model. Feet can differ in size, so base your choice on the larger measurement.

Also consider the shape of the toe box. A closed, narrow toe box offers less room than a model with a wider forefoot. For children, an adjustable hook-and-loop fastening is useful when laces are still difficult to manage.

Material and breathability

Mesh and other textiles are often lightweight and allow air to circulate. Synthetic leather and leather are generally easier to wipe clean, but they may offer different levels of breathability. Suede requires careful cleaning and should not simply be treated with lots of water.

Check the care instructions before buying. Some trainers can be cleaned with a damp cloth, while other models must not be put in the washing machine. For children's shoes with built-in lights, for example, the product information may state that machine washing can cause damage.

Sole, grip and intended use

A rubber outsole is common in casual shoes and sports shoes. Look at the tread and construction: a flat sole is suitable for everyday use, while a more pronounced tread can provide better grip on different surfaces. An EVA midsole is lightweight, but on its own it says nothing about whether the fit is right for you.

For use around the home, slippers or slip-ons are practical. According to the product description, the BIRKENSTOCK Arizona features an adjustable double buckle, a cork-latex footbed and an EVA outsole. These are specific features you can compare with a simple slide slipper.

Care for a longer lifespan

The right care helps keep materials and shape looking their best for longer:

  • Remove dirt with a soft brush or slightly damp cloth.
  • Do not use bleach unless the care label expressly permits it.
  • Allow shoes to dry at room temperature, away from direct heat.
  • Do not put suede, leather or models with electronic components in the washing machine without checking first.
  • Rotate your shoes if you wear them almost every day.
  • Check the sole, stitching and fastening regularly for signs of wear.

For slippers such as the PUXI Banana Boat Slide, rinsing with lukewarm water is possible according to the product information. The LEE Mule Slipper Robalo, on the other hand, must not be put in the washing machine and is designed to be cleaned with a damp cloth.

Frequently asked questions about trainers and shoes

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

Measure your foot length in centimetres and compare it with the size guide for the model you have chosen. Also check the fit and width. Do not automatically choose the same size for every brand or type of shoe.

How long do trainers last on average?

This depends on walking distance, the surface, body weight, material and care. A trainer worn for a daily commute will wear differently from a model worn only at weekends. Pay particular attention to soles becoming smooth, stitching coming loose and the insole becoming misshapen.

Which shoes are suitable for everyday use?

This depends on the surface and your routine. For casual wear, models with a rubber sole, an adjustable fastening and a suitable upper are practical. For sport, choose a model whose product information clearly describes its intended use, sole construction and fit.
