Buying shoes online: how to choose by fit, use and material

Buying shoes online seems straightforward: pick a brand, select your size and place the order. Yet many purchases turn out to be disappointing. A shoe can look appealing in photos, but be less suitable for long walks, intensive sports or daily use in changeable British weather.

So don't just focus on colour and brand name. The key differences are often in fit, sole, material and the intended use.

Common pitfalls when buying shoes online

1. Confusing a familiar trainer with a sports shoe

A model like the Nike Dunk Low, New Balance 574 or Lacoste trainers can work well with a casual outfit. That doesn't automatically mean the shoe is suitable for running or intensive training. In the product information, these models are primarily aimed at daily use, lifestyle or light activities.

If you're looking for sports shoes, you should therefore pay attention to features such as:

  • the type of midsole;
  • the flexibility of the sole;
  • ventilation of the upper;
  • grip on the surface;
  • the support that matches the activity.

For running, sports shoes like the adidas Runfalcon 5 are a more logical choice than a lifestyle model. For off-road trails, trail running shoes, such as models from Salomon, are a more specific option.

2. Only checking the EU size

Sizes can vary by brand, model and fit. An EU size 42 is not identical for every shoe. Where possible, check the foot length in centimetres and compare it with the product's size guide.

Also pay attention to the width:

  • Standard fit: suitable for many feet, but not automatically comfortable for wide feet.
  • Narrow model: can offer more hold, but may cause pressure on a wider forefoot.
  • Roomier model: gives more space to move, but can feel less stable on narrow feet.

For children's trainers, extra room is important, but a shoe that's too big can actually slip. A practical fastening, such as Velcro on the New Balance PC574EVN, makes putting on and taking off easier for little ones.

3. Letting marketing terms outweigh verifiable specifications

Words like "light", "stable" or "water-resistant" mean little without technical context. Look at the material and construction. A GORE-TEX membrane, for example on the Salomon Speedcross 5 GTX W, is mentioned in the product information as a component for water resistance and breathability. That's different from a guarantee that the shoe will stay completely dry in all conditions.

Also check the care instructions. Many sports shoes shouldn't go in the washing machine. Heat, a radiator or a tumble dryer can damage mesh, glue, rubber or synthetic overlays.

The most important specifications when buying shoes online

1. Choose the sole based on the surface

A rubber outsole with a relatively flat tread pattern is generally better suited to tarmac, school playgrounds and daily use. For mud, forest floors and loose terrain, deeper grooves and a clear tread pattern are more practical.

For trail running shoes, these points are particularly relevant:

  • Tread depth: deeper lugs can offer more grip on soft ground.
  • Rubber compound: partly determines durability and grip.
  • Flexibility: important for a natural roll on varied paths.
  • Protection: a sturdier upper can better withstand contact with branches and stones.

According to the product description, the Salomon Pulsar Trail 472100 has a rubber sole with 3.5 mm lugs and is designed for smoother terrain. The Salomon Speedcross 5 GTX W is described with a Contagrip TA sole with deep grooves for loose and mixed ground.

2. Look at the midsole and cushioning

The midsole largely determines how the shoe feels when you walk. Models in the range use different materials and systems. The New Balance 1906 models, for example, mention an ABZORB midsole and Stability Web technology. The New Balance U2002RCE also lists N-ergy.

These brand names aren't a universal quality standard. Assess them together with the intended use, fit and sole. For daily walking, a comfortable, stable midsole may be sufficient. For running, weight, roll and the surface also play a role.

3. Check the upper and care

A mesh upper can feel more breathable than fully synthetic or leather material. Leather and synthetic leather are often easier to wipe clean, but may be less ventilated. For children, durability and easy cleaning are usually more important than a fashionable finish.

Check before you buy:

  • the material of the upper;
  • whether the insole is removable;
  • the type of fastening;
  • the recommended cleaning method;
  • any information about water resistance.

If you're looking for women's trainers, alongside New Balance you'll also find various Nike Dunk Low models, such as the Nike Wmns Dunk Low NN DD1873-113 and Nike Wmns Dunk Low HM9655-001. The product information mentions a leather upper, a padded collar and a rubber sole with a pivot point for both.

For children, the New Balance 574 kids' trainers with Velcro are practical for school and daily use. The Lacoste L001 models have a synthetic leather and textile upper, an EVA insole and a rubber sole. The Skechers Meteor-Lights add lighting, but according to the product information they shouldn't go in the washing machine.

For men, the New Balance 2002, US Polo Assn trainers and Nike Manoa are suitable categories to compare. The Nike Manoa is a higher trekking and winter shoe with a nubuck leather upper and water-repellent construction according to the product description. That makes this model a different choice from low men's trainers for city use.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure both feet at the end of the day, as feet can be slightly larger then. Place your heel against a wall, measure to the longest toe and compare the result with the size guide for the model. If in doubt, also use information about standard, wide or narrow fit.

How long do sports shoes typically last?

The lifespan depends on use, surface, body weight, care and storage. Look out for visible wear on the tread, tears in the upper or a midsole that no longer feels even. Running shoes used only for walking wear differently to shoes used for regular training.

Can you wear running shoes every day?

You can, but it's not always practical. A running shoe is designed with a specific running surface, weight and roll in mind. For daily use on the street, a versatile lifestyle model may be more comfortable. Choose based on the activity you'll use the shoe for most often.
