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

Buying shoes online may seem straightforward, but an attractive photo tells you little about fit, grip and everyday comfort. A trainer that works well for a short walk is not automatically suitable as a running shoe. Likewise, a pair of flip-flops with an anti-slip tread may perform differently than expected on a wet tiled floor.

As a Joybuy Product Recommendation Officer, I filter product information for practical details. Pay particular attention to these three common pitfalls:

• Marketing language without measurable details: words such as “comfortable” or “lightweight” are only useful when information is also provided about the material, sole and fit.
• The wrong shoe for the activity: casual trainers, sports shoes, running shoes and trail-running shoes each serve a different purpose.
• Choosing a size based only on the EU size: an EU 42 may fit differently depending on the brand or model. Always check your foot length and the size guide.

Which specifications should you check?

1. Fit and available sizes

Measure your foot at the end of the day while standing. Take into account the socks you normally wear. Then compare the measurement with the product’s size guide. Also look for terms such as regular fit, a wide fit or a narrower version.

For example, according to the product information, the Puma Speedcat OG is available in a regular fit with a rounded toe. The size guide states that EU 42 corresponds to a foot length of 27 cm. The Crocs Crush Sandal, on the other hand, is described as having a closer fit around the toes; according to the product information, anyone wanting extra room or planning to wear socks may wish to consider going up a size.

2. Sole, cushioning and grip

For everyday use, comfortable shoes with a soft insole can be pleasant to wear. For running, the combination of cushioning, stability and a suitable outsole is particularly important. A flat rubber sole, as found on some lifestyle models, is not the same as a lugged sole designed for mud or loose ground.

Pay attention to the difference between:

• Rubber outsole: suitable for many everyday uses and often hard-wearing.
• TPU sole: can offer a sturdy construction and good grip, depending on the tread.
• EVA midsole: often used to keep weight low and provide a soft or responsive feel.
• Deep tread: relevant for walks, trail running and wet or loose ground.

You should not treat a brand’s claim about cushioning or joint comfort as a medical fact. According to adidas’s own product description, the Cloudfoam midsole is designed to provide cushioning and support. This tells you about the design, but does not guarantee a particular experience when walking or running.

3. Material and care

Leather women’s shoes, men’s shoes and unisex shoes require different care from mesh trainers. Textile can be breathable, but it is not automatically waterproof. A model with a membrane may offer greater protection from rain, but always check the care instructions and product terms.

According to the product information, the Salomon XA Pro 3D v9 GTX features a GORE-TEX membrane and a Contagrip outsole. On paper, this makes the model interesting for walking and trail running in changeable conditions. According to the product specifications, the PUMA Speedcat models have a leather upper, a textile lining and a rubber sole. They are therefore primarily intended for casual use, rather than technical walking routes.

Choose based on how you’ll use them, not just their appearance

• Everyday and casual wear: look at weight, fastening, ventilation and care requirements. Vans, Puma Speedcat and Skechers trainers work well with a casual outfit, but do not have the same properties as running shoes.
• Sport and training: look for a secure fastening, breathable upper, cushioning and a sole suited to the surface.
• Road running: choose a model with a midsole that the specifications state provides cushioning, and check that the fit leaves enough room around the toes.
• Trail running and walking: look for grip, toe protection, stability and, where relevant, a water-repellent or waterproof membrane.
• Home, bathroom or leisure: flip-flops, slip-ons, clogs and Crocs are practical thanks to their easy entry. On wet floors, a clearly defined anti-slip tread is more important than a soft footbed alone.

Frequently asked questions about buying shoes online

How do I determine my shoe size when buying online?

Measure both feet in centimetres and use the size of the longer foot. Compare the result with the size guide for the specific model. Also check whether the shoe has a regular, narrow or generous fit. If you are unsure, it is important to check the returns policy and your statutory consumer rights in advance.

How long do shoes last on average?

Their lifespan depends on use, the surface, body weight, care and material. A pair for everyday use wears differently from running shoes or trail-running shoes. Look out for loose seams, a tread that has become smooth, cracks in the sole and a compressed midsole. Only wash or dry shoes according to the care advice.

Are lightweight shoes always more comfortable?

Not necessarily. A lower weight can feel pleasant, but fit, support, cushioning and grip all determine how a shoe feels. So do not compare weight alone; also consider the sole construction and intended use. A lightweight model for the city may be less suitable for a wet woodland path than a slightly sturdier pair.
