Buying shoes online: how to choose the right pair and avoid a costly mistake

Buying shoes online seems simple: choose a style, select your size and check out. Yet many purchases disappoint because of a poor fit, unclear material information or shoes that aren’t suited to the way you’ll use them. A casual trainer, for example, isn’t automatically suitable for running, and a water-repellent boot doesn’t offer the same protection as a fully waterproof shoe.

Use the checks below to compare men’s trainers, women’s shoes, children’s shoes, sports shoes and boots based on practical features, not just looks or brand name.

Three common pitfalls when buying shoes online

1. Looking only at the EU size

A size 45 doesn’t have exactly the same internal length or fit across every brand. The width of the toe box and the height of the instep can vary too. So, when the information is available, check the foot length in centimetres and compare it with the product’s size chart.

This is especially important if you’re looking for size 45 shoes, running shoes or styles with a wide toe box. A shoe that seems right in length may still feel uncomfortable if it has a narrow fit.

2. Confusing marketing claims with product features

Terms such as “cushioning”, “performance” or “comfort” don’t tell you much on their own. Look for details you can check:

  • What material is used for the upper?
  • Is the sole made from rubber, EVA or another material?
  • Is the fastening adjustable?
  • Is the shoe described as water-repellent or waterproof?
  • Is the style intended for everyday wear, walking, training or running?

A brand’s own research may suggest that a particular technology improves comfort or grip. That’s a brand claim, not a universally established result. So, when comparing styles, focus on the stated materials, construction and sizing information.

3. Choosing shoes for the wrong activity

Casual shoes and leather shoes are generally designed for everyday wear. Sports shoes may offer more flexibility and cushioning, but not every sports style is suitable for running. Walking shoes and trekking boots often have a deeper tread, while trainers are mainly designed for pavements and streets.

Think about where you’ll wear your pair most: at work, on your commute, on unsurfaced paths, in the rain or during intense exercise.

Which specifications are worth checking?

Fit and size

Measure both feet at the end of the day, when they’re often slightly larger than in the morning. Note the length of your longer foot, then check the product table. Also look out for:

  • Standard width or wide fit
  • Room around the toes
  • A secure heel fit
  • Adjustability with laces, straps or another fastening
  • The thickness of the socks you plan to wear

Some PELLIOT styles are available in both a standard and a slim version. The product information says the standard version is designed to fit most feet, while the slim version has a narrower fit.

Material and breathability

Mesh and woven textiles generally let more air through than fully enclosed synthetic materials. This can be useful in sports shoes and summer casual shoes. Leather shoes have a different look and structure; check whether the material is full-grain leather, nubuck, synthetic leather or a combination.

One example is the adidas Samba OG, with an upper made from full-grain leather and suede overlays. The US POLO ASSN ARIS001M combines synthetic leather with mesh. These materials have different care requirements and levels of breathability.

Sole, grip and conditions of use

A rubber outsole can provide grip and wear resistance, but the tread also affects what the shoe is suited to. A flat sole often works well for city use, while a deeper tread makes more sense for walking or off-road terrain.

Check the wording carefully when it comes to waterproof shoes. “Water-repellent” doesn’t automatically mean a shoe will stay waterproof for extended periods. The Nike Manoa is described in the product details as water-repellent and has a nubuck leather upper. Care instructions recommend wiping it with a damp cloth and letting it dry naturally.

Care and lifespan

How long shoes last depends on how they’re used, their materials, the surfaces they’re worn on and how they’re cared for. Let wet shoes dry naturally and don’t put them straight on a radiator. Clean leather with a suitable product and mesh with a soft, damp cloth. Always check the care label: several styles in the range shouldn’t be put in the washing machine or tumble dryer.

Where possible, alternate between two pairs. This gives the material time to dry and reduces continuous wear on the sole. It’s also important to check the size of children’s shoes regularly, as their feet grow quickly.

Frequently asked questions about buying shoes online

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

Measure both feet in centimetres, preferably at the end of the day. Use the size for your longer foot and check the chart on the product page. Also check the stated width and fit.

How long do shoes bought online last?

It varies depending on the materials and how you use them. Trainers worn every day will wear out faster than a pair you alternate with another. Look out for wear on the tread, seams coming loose and the shoe losing its shape. Follow the care instructions to help prevent unnecessary wear.

Are waterproof shoes always suitable for rain?

Not necessarily. A product may be water-repellent without being fully waterproof for extended periods. Check the exact description, seams, fastening and care instructions before choosing a style for wet conditions.
