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

Buying trainers seems straightforward, until you have to choose between men’s trainers, women’s trainers, children’s trainers, running shoes and casual trainers. An attractive style isn’t automatically suitable for long walks, sport or everyday wear. So start by looking at the fit, materials and the surfaces you plan to wear them on.

Common pitfalls when buying trainers

1. Wearing a good-looking trainer for the wrong activity

Casual trainers are often designed for everyday wear and a walk around town. That doesn’t mean they’re suitable for running or intensive training. A flat sole and relatively firm construction can work well with a casual outfit, but may offer less support for repeated running movements.

For running shoes, the midsole, weight, grip and fit are all important. Gym trainers have different requirements, such as flexibility and a stable outsole.

2. Relying only on terms such as “comfort” and “cushioning”

Marketing copy often uses phrases such as comfortable trainers, well-cushioned trainers or lightweight. Check the technical details behind these claims:

  • Is the midsole material specified?
  • Does the shoe have a breathable upper?
  • Is the sole designed for tarmac, indoor use or off-road terrain?
  • Is there information about the width and the actual foot length?

According to adidas’ own information, certain Adizero models use Lightstrike Pro, ENERGYRODS and a Lighttraxion outsole, for example. These are verifiable product specifications. Whether the combination feels comfortable will depend on your running style and preferences.

3. Choosing a size without checking the size guide

An EU size can fit differently depending on the brand or model. “True to size” is useful information, but also check the foot length in millimetres or centimetres if it’s available. The PELLIOT Running Shoes, for example, have a size guide showing that EU 37 corresponds to a foot length of 235 mm, while EU 38 corresponds to 240 mm.

When trying them on, check for:

  • about a thumb’s width of space for your toes;
  • no pressure on the instep or little toe;
  • a heel that doesn’t lift as you walk;
  • enough room when wearing sports socks.

Important specifications to compare

Upper: textile, mesh, leather or synthetic material

A mesh upper generally allows air to circulate more easily than dense synthetic material. This can be useful for walking, travelling and warm days. A canvas upper, such as on certain Converse trainers, has a casual look and can feel lightweight. Leather and synthetic materials are often easier to wipe clean, but breathability varies depending on the construction.

Check the care instructions too. Some shoes shouldn’t be machine-washed. For the Vans Old Skool, for example, it’s recommended that you avoid high temperatures and machine washing.

Midsole and cushioning

The midsole plays a large part in how a shoe feels. EVA foam is commonly used in running shoes and lightweight walking shoes. PELLIOT models specify an elastic EVA midsole and a ROCKYTEC rubber outsole. According to the product description, these shoes are designed for use on surfaces ranging from tarmac to off-road terrain.

That makes them worth considering if you’re looking for a versatile sports shoe, but always compare the fit and sole width with your foot. Cushioning is no substitute for the right size.

Outsole and grip

A rubber outsole is common on casual trainers, children’s shoes and sports shoes. For everyday use on UK streets, a hard-wearing tread is often enough. If you regularly walk on wet paths, mud or loose surfaces, it’s worth taking a closer look at the tread and the recommended use.

A flat sole, as found on some lifestyle models, suits casual wear. For running or trail-style routes, a model with a clearly defined tread makes more sense.

Frequently asked questions about buying trainers

How do I work out what size trainers to buy?

Measure both feet at the end of the day, when they may be slightly larger. Compare your longer foot with the brand’s size guide. Alongside the EU size, check the measurements in centimetres or millimetres, and allow for the thickness of your socks.

How long do trainers last on average?

Their lifespan depends on how often you wear them, your body weight, the surfaces you walk on, how you care for them and the materials they’re made from. Casual trainers worn every day will wear differently from running shoes used several times a week. Look out for a worn-smooth tread, cracks, a midsole that has compressed unevenly or seams coming loose. These are practical signs that it’s time to replace them.

Can I wear running shoes every day too?

You can, but they’re designed for running movements and aren’t always suited to standing for long periods or casual wear. Check that the sole and upper suit your everyday surroundings. For commuting and walking, comfortable trainers with a regular fit may be more practical; for training, choose a model with specifications that suit your running goals.
