Buying shoes online: how to choose the right pair for your needs

Buying shoes online may seem simple, but a great photo and a low price don’t tell the whole story. The wrong fit, a sole without the right grip or a material that doesn’t suit how you’ll use them can leave you with a pair you hardly ever wear.

That applies to online trainers, running shoes, trail running shoes, walking boots and sports shoes. Men’s, women’s and children’s shoes also differ in comfort, fastening and care. Use these practical checks to compare your options more effectively and avoid a costly mistake.

Three pitfalls to avoid when buying shoes online

1. Taking “comfortable sole” to mean too many things

The word “comfort” doesn’t tell you much without more detail. Check the midsole, the footbed and the construction of the outsole. An EVA or IMEVA midsole may feel lightweight, while a Memory Foam footbed may simply provide extra cushioning inside the shoe. That doesn’t automatically make a style suitable for running or long walks.

2. Mistaking grip for suitability

A rubber sole generally offers more grip than a smooth lifestyle sole, but the tread determines where the shoe is suitable. A flatter pattern is often fine for city wear. On gravel, mud or wet paths, deeper grooves, a sturdy tread and a rubber compound matter more. Check whether the product description mentions grip on wet and dry surfaces, rather than simply promising that the shoes are “non-slip”.

3. Assuming the same size means the same fit

An EU size isn’t identical across every brand. The shoe’s last, width, toe room and lining thickness all affect the fit. Measure both feet at the end of the day and compare their length with the size guide. Children’s shoes need extra attention: an easy-to-adjust hook-and-loop fastening may be more practical than laces, but the shoe shouldn’t be loose around the foot.

Which specifications should you check?

1. Intended use and sole tread

First, decide where you’ll wear the shoes:

  • Everyday wear: a flexible rubber sole and a standard fit are often practical.
  • Running: look for a lightweight construction, a cushioned midsole and enough heel stability.
  • Trail running or outdoor activities: check the tread, toe protection and grip on different surfaces.
  • Walking: look for support, flexibility and a sole that isn’t too smooth.
  • School and play: a reinforced toe, easy fastening and a flexible tread are useful features.

A comfortable pair of trainers may be ideal for commuting, but not for a long trail. Conversely, a trail shoe may feel unnecessarily stiff or bulky in the city.

2. Material and breathability

An upper made from mesh or textile generally lets more air through than one made entirely from synthetic material or leather. This can feel more comfortable during exercise and on warmer days. Leather and synthetic leather are often easier to wipe clean, but need different care.

Always check the material details. For example, the PUMA Speedcat OG has a leather upper, a textile lining and a rubber sole. The Vans Old Skool has a textile upper and lining, with a rubber sole. This information helps you make a more realistic judgement about care, breathability and when to wear them.

3. Fastening, width and sizing information

Laces give you an adjustable fit, while hook-and-loop fastenings can be handy for children or anyone who wants to put their shoes on quickly. Also check the stated width, such as D or G, and whether the listed size has a standard fit.

If you’re unsure, the insole length in centimetres is often a more useful point of comparison than the EU size alone. Allow for socks and a little extra room in children’s shoes, but don’t choose a size so large that it fails to hold the foot securely.

Frequently asked questions about buying shoes online

How do I work out my shoe size when ordering online?

Measure both feet on a sheet of paper and note the longer measurement. Compare this length with the size guide for the specific style. Also check the stated width and fit. An EU size alone doesn’t always give you enough information.

How long do trainers and sports shoes last?

That depends on how often you wear them, the surfaces you use them on, your body weight, the materials and how well you care for them. Check the soles for smooth patches, cracks and noticeably reduced cushioning. For running shoes, the number of hours you run in them and the way your foot lands also matter. A shoe worn only for everyday use may wear differently from one used for training several times a week.

Can I wear running shoes every day?

You can, but whether they’re practical depends on the design. A trail shoe with a deep tread may feel less smooth on tarmac and wear out more quickly. A lightweight running shoe may be suitable for walking and commuting, provided the fit and grip suit your route. Always check the product description and choose based on how you’ll use the shoes, not just the brand name or appearance.
