Choosing shoes without regret: a practical guide to sport, everyday use and outdoor activities

Buying shoes online may seem simple, but an attractive photo says little about fit, surface or everyday comfort. A running shoe is not automatically suitable as a trainer, and football boots designed for natural grass will not work well in a sports hall. By checking the material, size and intended use carefully, you reduce the chance of ending up with a pair that stays unworn in the cupboard after just a few outings.

Common pitfalls when buying shoes

1. Using one pair for every situation

A low-cut casual shoe may be perfectly suitable for walking around town, but it often lacks the grip, cushioning or stability needed for running. Conversely, a technical running shoe may feel unnecessarily stiff or look out of place for everyday use. So start by considering the surface and type of movement you need the shoes for:

  • Roads and asphalt: sports shoes with a cushioned midsole and hard-wearing tread.
  • Gravel and trails: trail running shoes with extra grip and protection against dirt and stones.
  • Natural grass: football boots or Nike lacrosse shoes with a suitable FG stud configuration.
  • Sports halls: indoor football shoes with a non-marking rubber sole.
  • Everyday use: trainers or casual shoes with a fit suited to standing and walking for long periods.

2. Looking only at the EU size

An EU size is not identical across every model. The shape of the toe box, the width of the last and the thickness of the lining all affect how a shoe fits. Therefore, check the stated foot length in millimetres or centimetres, and measure both feet at the end of the day.

A practical method:

  1. Place your foot on a sheet of paper with your heel against a wall.
  2. Mark the furthest point of your foot.
  3. Measure both feet and use the larger measurement.
  4. Compare the result with the size chart for the specific model.
  5. Leave some room around the toes in sports shoes, especially when running longer distances.

3. Confusing marketing claims with guarantees

Terms such as “maximum grip”, “energy return” or “suitable for every terrain” are not always directly comparable. Instead, assess the specific details: sole type, midsole material, upper, fastening and recommended surface. When a performance claim is mentioned only by a brand, we treat it as a brand claim. For example, according to the adidas product description, the combination of Lightstrike Pro and ENERGYRODS creates a responsive feel; this is not a guarantee for every runner.

The key specifications explained

Sole and surface

The sole largely determines where you can use your shoes safely and practically. An FG sole with studs is intended for firm natural grass. Do not routinely wear football boots with this type of sole on a sports floor. For indoor football, non-marking rubber soles are important: they are designed to provide grip without leaving obvious marks behind.

For trail running, pay attention to the rubber compound and tread. A sole with deeper studs is useful on mud, loose ground and uneven paths. On asphalt, however, this type of tread may wear down more quickly and feel less flexible.

Midsole and cushioning

The midsole determines how the shoe feels underfoot. EVA, Bounce, Cloudfoam and Lightstrike are different material or technology names. Do not compare the name alone; consider how it is used as well. A lightweight, responsive model for tempo training has a different purpose from a softer model for easy runs.

For the adidas Adizero Boston 13, the product description lists a Lightstrike Pro midsole, ENERGYRODS and a Lighttraxion outsole with Continental Rubber at the front. The stated size is EU 39 1/3, with a foot length of 246 mm. This makes the model particularly interesting for runners who can match their measurements accurately to the size chart.

Upper, fit and care

A mesh upper can feel airy during sport, while leather or synthetic leather gives trainers more structure. Check the fastening too. Laces offer an adjustable fit; a wide, fixed opening is more convenient for relaxed everyday use, but may provide less adjustment.

Also pay attention to the care instructions. Many models must not be put in the washing machine. The product descriptions for several adidas and Vans models recommend cleaning with a damp cloth and allowing them to dry naturally, away from direct heat. This helps limit deformation and damage to glued joins.

Frequently asked questions about shoes

How do I measure my foot for online shoes?

Measure both feet while standing, from the back of the heel to the furthest point of the toe. Use the larger measurement and compare it with the model’s size chart. Also check whether the manufacturer states that the fit is regular, narrow or wide.

How long do shoes last on average?

Lifespan depends on use, surface, body weight and care. Sports shoes can wear down more quickly with intensive daily use. Look out for flattened tread, cracks in the upper, parts coming loose or a compressed midsole. Alternating between two pairs can extend the usable life of each pair.

Can you wear running shoes as casual shoes too?

You can, but it is not always practical. Running shoes often have a sole and fit designed for repeated running movements. For everyday use, trainers or casual shoes are usually the more sensible choice. Always choose based on your main activity and check that the sole is suitable for the surface you walk on.
