How to choose trainers and running shoes without making the wrong purchase

A new pair of trainers or running shoes may seem easy to find. Yet many disappointing purchases are caused by an unsuitable fit, a sole that does not match the intended use or material that does not allow enough airflow. If you focus only on colour, brand or a familiar name, you could end up with painful pressure points, poor grip or shoes that wear out quickly after just a few weeks.

This buying guide helps men, women and parents compare more effectively. Whether you are looking for men's trainers, women's trainers, children's trainers, everyday shoes or sports shoes, consider how they will be used first and the marketing second.

Three common pitfalls when choosing trainers and running shoes

1. Familiar cushioning does not automatically mean the fit is right

Terms such as Memory Foam, Cloudfoam and SOFTFOAM+ describe a material or construction, but they do not tell you whether the shoe suits your foot. A narrow foot may move around in a broad last, while a wide forefoot may not have enough room.

So pay attention to:

  • the stated fit, such as normal or regular fit;
  • the shoe width, for example D;
  • the amount of room around the toes;
  • laces or hook-and-loop fastening that allow you to adjust the shoe.

A sole with cushioning foam is primarily a product specification. How soft it feels varies from person to person and depends on your running style and the surface.

2. A running shoe is not always suitable as an everyday trainer

Lightweight running shoes are designed with movement and ventilation in mind. A road-running model may feel comfortable on tarmac but be less suitable for muddy paths. Trail running shoes often have a lugged sole with more grip, but may feel less smooth on slippery indoor floors.

Conversely, comfortable trainers for school, work or walking do not necessarily offer the features you need for regular running training. Always check the intended use: short distances, everyday walking, fitness, outdoor play or off-road terrain.

3. “Breathable” material does not prevent every moisture problem

A mesh upper can allow air to pass through, but the level of ventilation also depends on the lining, socks and fit. A fully synthetic shoe may feel different from a model made with textile or woven mesh.

So check the material composition. Textile, mesh and woven uppers can help with ventilation, while synthetic leather may provide more structure and protection. None of these features alone guarantees dry or comfortable feet.

Important specifications to check

Size and fit

Ideally, measure your feet at the end of the day, when they are often slightly larger. Compare the length of your foot with the size chart for the specific model. An EU size is not identical across every brand; adidas, for example, also uses half sizes such as 41 1/3 and 44 2/3.

Also consider the space around the toes. For running, a little extra room can be useful, particularly if you wear thicker socks. For children, the correct size is more important than deliberately choosing a large allowance for growth. When choosing children's trainers, also check whether the fastening is easy to adjust.

Sole, cushioning and grip

The sole usually consists of several parts:

  • insole: the part your foot rests on;
  • midsole: often made from EVA or a branded foam;
  • outsole: the part that contacts the ground.

A rubber sole may be suitable for everyday use and provide grip on many paved surfaces. For woodland paths, wet stones or loose ground, a deeper tread is more relevant. Do not look only at the name of the technology; consider the material, tread and described intended use.

Material and care

Before buying, check whether the shoes are machine washable. According to the product information, the Skechers BOBS Sport Squad Chaos 118300-BBK can be washed on a cold, gentle cycle and should be left to air dry. According to the supplied instructions, the adidas Runfalcon 5 must not be machine washed; wiping it with a damp cloth is the recommended method.

Do not use a tumble dryer, bleach or harsh cleaner when the care label advises against it. Heat can damage glue, foam and structural panels.

Frequently asked questions about trainers and running shoes

How long do trainers and running shoes last?

Their lifespan depends on use, body weight, the surface, care and the extent to which the sole wears down. Regularly check the tread, tears in the upper and deformation of the midsole. With everyday shoes, wear may develop gradually; with running shoes, you will often notice sooner that the cushioning and stability feel different.

Can I use running shoes as everyday shoes too?

This is possible with models described as suitable for road use and easy everyday running. Bear in mind that they may wear out more quickly if you also use them for walking, work and sport. Trail running shoes make most sense when you regularly run on off-road or wet surfaces.

How do I choose between Memory Foam, Cloudfoam and standard cushioning?

First compare the construction and intended use. Memory Foam is generally a term used for an insole or footbed, while Cloudfoam is listed by adidas as a midsole material. Also consider the fit, sole material, weight and care requirements. A branded foam name is no substitute for checking the size and running surface.
