Buying shoes online: how to choose the right fit and design

Buying shoes online may seem straightforward, but an attractive photo and a low price say little about whether they are suitable for your feet or activity. Everyday trainers have different requirements from running shoes, trail running shoes or football boots. Carrying out the right checks beforehand can help you avoid a poor purchase, an uncomfortable fit or premature wear.

Common pitfalls when buying shoes online

1. Confusing a sporty look with technical suitability

Not every trainer is suitable for running. A casual model may be perfectly adequate for commuting, but it may lack the cushioning, stability or grip you need over longer distances. The same applies to team sports: football boots with AG studs are designed for artificial grass, while lacrosse boots with FG studs are generally suited to natural grass.

Always check the stated activity and surface. If you are looking for basketball shoes, look for a sturdy construction and a sole suitable for the relevant sports floor. For walking in the Netherlands, a comfortable shoe with sufficient tread is often more practical than a heavy mountain boot.

2. Relying solely on the EU size

An EU size is not identical across every brand or model. Width, toe-box shape and instep height also affect the fit. Some product pages state that a shoe has a standard fit, while others provide a foot length in millimetres.

Ideally, measure your foot at the end of the day, wearing the socks you normally wear. Compare the measurement with the size chart for the specific model. For example, the PELLIOT models list a foot length of 260 mm for EU 42 and 270 mm for EU 44. This is more precise than relying solely on your usual shoe size.

3. Reading marketing claims without checking the specifications

Terms such as “lightweight”, “maximum grip” or “premium comfort” are only useful when supported by concrete information about the material, sole and construction. According to the product description, the Salomon XA Pro 3D v9 GTX, for example, has a GORE-TEX membrane, a Contagrip rubber sole and a 3D Advanced Chassis. These are verifiable product features. Their practical performance may vary depending on the conditions and the wearer.

Also consider care requirements. Suede, mesh and synthetic leather do not all require the same treatment. A shoe that can only be cleaned with a damp cloth is less suitable if you often walk through mud.

Important specifications to compare

Fit and sizing

Look at:

  • Foot length in centimetres or millimetres, if available.
  • Descriptions such as standard, narrow or wide fit.
  • The shape of the toe box and the amount of room available for your toes.
  • A lace-up fastening, slip-on construction or Quicklace system.
  • Whether the insole is removable.

A little room around the toes is desirable for walking and running, but your heel should not lift out of the shoe as you walk. For high-intensity sports, an easily adjustable fastening is important to minimise movement inside the shoe.

Sole, grip and surface

The sole largely determines what a model is suitable for. Look out for the difference between:

  • Flat rubber soles for casual use, trainers and skate-inspired models.
  • Treaded soles for walking and everyday outdoor use.
  • Trail soles with a deeper rubber tread for gravel, woodland paths and changing surfaces.
  • AG studs for artificial grass in football.
  • FG studs for firm natural grass, including for lacrosse.

A heavily treaded sole is not automatically comfortable on smooth indoor floors. You should also use football boots on the surface they were designed for. This helps ensure that grip and wear are better suited to one another.

Material, cushioning and care

Mesh and textile generally provide ventilation and keep weight down. Synthetic leather is easy to wipe clean and can offer a more enclosed feel. Suede has a smart appearance, but requires careful maintenance and is less practical in frequent rain.

Midsoles may use materials such as EVA, Cloudfoam or Memory Foam. Treat these as descriptions of the construction, not as a guarantee of a particular level of comfort. According to the product information, several models feature a shock-absorbing or cushioned midsole; your fit, gait and length of use remain decisive.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure both feet on a sheet of paper and use the longer measurement. Compare it with the size chart for the specific model. Also check the stated fit and width. If you are unsure about choosing between sizes, it is worth checking the returns policy before ordering.

How long do shoes bought online last?

Their lifespan depends on the material, use, surface, body weight, care and how often they are worn. Everyday trainers wear differently from running shoes or sports shoes. Check the sole for smooth patches, cracks and parts coming loose. Allow wet shoes to dry naturally and, if possible, alternate between several pairs.

Are waterproof shoes suitable for every season?

According to the product description, a waterproof membrane can offer protection from moisture, but it does not automatically make a shoe suitable for every situation. Also consider ventilation, sole tread, insulation and care requirements. Breathable, lightweight shoes may be more comfortable on warm days, while waterproof shoes with good grip are often more practical for rainy walks.
