Buying trainers without making a costly mistake: how to compare comfort, materials and fit

When you’re looking to buy trainers online, you’ll soon come across terms such as “extra comfort”, “sporty” and “suitable for all-day wear”. On their own, these words don’t tell you much. A low-top trainer for your commute calls for different features from a pair of road-running shoes or a model for long walks.

Most disappointing purchases come down to three familiar pitfalls:

  • Choosing on looks alone: a trendy style may have a narrow fit, little ventilation or a stiff sole.
  • Confusing Memory Foam with a good fit: a soft insole won’t make up for the wrong size or too little room around your toes.
  • Overlooking materials and care: mesh usually offers good ventilation, while leather and synthetic leather respond differently to rain, dirt and cleaning products.

With the right checks, you can compare men’s trainers, women’s trainers, casual trainers and sports trainers based on the features that matter in everyday use.

The key specifications to check when buying trainers

1. Fit, size and width

First, check whether the style comes up true to size and whether it has a standard width. An EU size chart is useful, but the stated foot length or width often gives you a better guide. Some styles, for example, specify a D width. This is useful information if you need a narrower or roomier fit.

Don’t automatically order the same size in every brand. Nike Dunk Low, Puma Speedcat, Vans Old Skool and New Balance trainers can all feel different because of the shape of the toe, the lining and the sole. So check:

  • the available sizes, for example sizes 37 to 47;
  • whether the fit is described as “true to size” or differs from standard;
  • the room around the toes;
  • the support around the heel and instep;
  • whether the insole can be removed.

2. Sole and intended use

A rubber sole usually offers grip and durability, but the tread makes a difference. A flat sole suits casual wear around town. A treaded sole is more practical on wet pavements, walking trails or changing surfaces.

Regular lifestyle trainers aren’t automatically suitable for running. For running shoes, look for a breathable upper, suitable cushioning, a secure fit and an outsole designed for the surfaces you’ll be running on. According to the product description, the adidas Supernova Ease is designed for short to medium-distance runs and features a mesh upper, Dreamstrike midsole and rubber studded outsole. These specifications make it more suited to running than a flat-soled casual trainer.

3. Materials, ventilation and care

Mesh trainers usually let more air through than fully enclosed styles. This can be comfortable when you’re wearing them for long periods, but mesh is more prone to dirt and moisture. Leather trainers and styles made from synthetic leather are often easier to wipe clean. Always check the care instructions, though.

An upper made from leather, textile or synthetic material affects more than just the look. It also influences flexibility, ventilation and care. The Vans Old Skool in this selection, for example, has a textile upper and rubber sole. The product information advises avoiding high temperatures and machine washing, among other things.

A few more styles to compare

For a classic everyday look, you could also consider the Vans Old Skool, Converse Star Player 76 OX or Vans Hylane. If you’re after a leather look, compare the Nike Dunk Low or Puma Speedcat by their uppers, fit and soles. According to the product information, the Puma Speedcat has a leather upper, textile lining and rubber outsole. With this type of low-top trainer, check that its flat construction suits how you plan to use it.

When shopping for women’s and men’s trainers, it’s best not to focus solely on the marketing category. Many styles have a unisex or similar shape. The actual sizing, width and foot length matter more than the label.

Frequently asked questions about buying trainers

How do I find the right size when buying trainers online?

Measure both feet at the end of the day, as they’re often slightly larger then. Compare your longer foot with the size chart for the specific style. Also check whether the shoes come up true to size and whether width information is available. If you’re unsure, it’s worth checking the stated foot length as well as the EU size.

How long do comfortable trainers last?

Their lifespan depends on how far you walk or run, your body weight, the surface, the materials and how well you care for them. Casual trainers for the office and shopping wear differently from running shoes. Look for wear on the rubber sole, seams coming loose, a misshapen heel and a compressed midsole. Only wash your shoes if the product information says it’s safe to do so, and leave them to air-dry.

Are Memory Foam trainers suitable for running?

Not necessarily. Trainers with Memory Foam may have a soft insole, according to the product description, but that doesn’t tell you anything about stability, the outsole or whether they’re suitable for running. For training, it’s better to compare styles with a clearly stated running purpose, a suitable midsole and grip that’s right for your running surface.
