Buying shoes online: how to choose a model that suits your needs

Buying shoes online seems simple until you have to choose between sports shoes, trainers, running shoes, trail running shoes, walking shoes and children’s shoes in different sizes. An attractive photo and a familiar brand name do not tell you enough about fit, grip or everyday comfort.

Most disappointing purchases result from three recurring pitfalls:

• Choosing the wrong size based only on the EU number. A size 42 can fit differently depending on the brand and model. Foot width and the amount of room around the toes also matter.
• Using a running shoe on every type of terrain. A lightweight running shoe designed for tarmac is not automatically suitable for mud, wet rocks or unpaved paths.
• Confusing marketing claims with guaranteed performance. Terms such as “maximum cushioning” or “anti-slip” should be assessed based on the materials, tread pattern and stated intended use.

What should you look for when buying shoes online?

1. Fit: look beyond the size

When buying women’s shoes, men’s shoes or unisex shoes, always check:

• the size chart for the specific model;
• the recommended foot length in millimetres;
• the shoe width, such as G or D;
• the type of fastening;
• whether the shoe has a standard, narrow or roomy fit.

A secure fastening is particularly practical for children’s shoes. For example, the Skechers Meteor-Lights 401495L-BKBL in size 33 has a standard fit, shoe width G and a hook-and-loop fastening. The product information states that this model fits true to size. Still, check the current size chart before ordering, as children’s feet grow quickly.

When buying online, you can measure your foot at home. Place your foot on a sheet of paper, mark the heel and longest toe, then compare the measurement with the product page. Measure both feet and use the larger measurement.

2. The sole and grip should suit the surface

A rubber sole generally offers greater durability than a simple foam sole, but the tread pattern determines how much grip you have on a particular surface. Pay attention to the difference between:

• Tarmac and the gym: a flatter rubber tread can provide a smooth roll-through.
• Park paths and gravel: a versatile tread offers more support on loose surfaces.
• Mud, wet rocks and mountain paths: deeper lugs and an outsole rubber designed for terrain are practical.
• Everyday use: comfort, flexibility and durability are often more important than an aggressive tread pattern.

According to the product description, the Salomon XA Pro 3D v9 GTX has a Contagrip rubber sole and a 3D Advanced Chassis. The manufacturer describes this model as suitable for trail running and walking. The product page also mentions a GORE-TEX membrane. This can help in wet weather, but water resistance does not automatically make a shoe suitable for prolonged submersion.

3. Upper, cushioning and ventilation

A mesh upper can allow air to circulate while keeping the weight low. Synthetic overlays can provide additional support or durability. Leather and synthetic materials are often easier to wipe clean, but they may breathe differently from open mesh.

For running, the following details are relevant:

• Midsole: EVA foam and other cushioning materials affect how the shoe feels underfoot.
• Weight: lightweight shoes can feel comfortable over longer distances, but a lower weight alone says nothing about stability.
• Ventilation: mesh is practical in warm weather and during intensive use.
• Support: a firm heel construction and well-adjusted lacing can contribute to a stable fit.

According to the product description, the PELLIOT Running Shoes Unisex Lightweight Cushioning uses an EVA midsole and a ROCKYTEC rubber outsole. The manufacturer lists uses ranging from city roads to mountain paths. Treat this information as a product specification and match your choice to your own terrain and running style; it is not a guarantee of a particular sporting performance.

Final checks before placing your order

2. Compare your foot length with the size chart. Do not rely solely on a previously worn model from the same brand.
3. Choose according to use. Nike shoes, New Balance shoes and Skechers shoes can include both sporty and casual models. The brand name does not automatically determine the intended use.
4. Check the care instructions. Some models must not be machine-washed. According to the product information, the Nike Zoom Vomero 5 should be washed in cold water and air-dried; the Salomon XA Pro 3D v9 GTX must not be machine-washed, according to the description.
5. Pay attention to the statutory guarantee. A statutory guarantee of at least two years is mentioned for many of the products listed. Your statutory rights depend on the applicable EU and Dutch consumer rules.

Frequently asked questions about buying shoes online

How do I know which shoe size to order online?

Measure both feet in millimetres and compare the larger foot with the size chart for the chosen model. Also check the width and whether the shoe has a standard, narrow or roomy fit. For children’s shoes, it is sensible to measure again regularly.

Which shoes are suitable for walking in the rain?

Look for a rubber outsole with a suitable tread and, where necessary, a waterproof membrane. The product information for the Salomon XA Pro 3D v9 GTX mentions GORE-TEX and Contagrip. For everyday use in light rain, a regular trainer may be sufficient, but always check the care advice and the limitations of the material.

How long do shoes bought online last?

This depends on use, the surface, body weight, care and materials. Intensive running and trail running generally wear down a sole faster than occasional everyday use. Rotate your shoes, allow moisture to evaporate thoroughly and follow the manufacturer’s cleaning instructions.
