Buy shoes online without making the wrong choice: how to choose the right size, material and use

Buying shoes online may seem straightforward, but an attractive product photo does not tell you everything. A sole may be less suitable for long walks in real life, children’s shoes may become too small sooner than expected and running shoes may have a fit that does not suit every foot.

The Joybuy Product Recommendation Officer selects products based on verifiable details such as materials, sizing, fastening, sole and intended use. This helps you look beyond marketing terms and make a more informed choice.

Three common pitfalls when buying shoes online

1. Focusing only on appearance

Sporty trainers with a sleek profile are not automatically suitable for running. A racing model, for example, may have a firm, close-fitting shape that feels comfortable during intense training but is less suitable for everyday wear.

2. Ordering your standard size without checking

Sizes vary between brands and models. An EU 42 does not have the same internal length or width in every shoe. With children’s shoes, room for growth also matters. Always check the size chart and measure the foot.

3. Treating features as facts

Terms such as “waterproof”, “breathable” or “extra stable” should be checked against the product specifications. When it comes to brand claims, according to the brand’s own research, a particular construction may offer more grip or ventilation, for example, but this is not a guarantee for every user or surface.

What should you check before buying shoes online?

1. Fit and available sizes

Measure the foot at the end of the day, when it usually takes up slightly more space. Place the foot on a sheet of paper, draw around it and measure from the heel to the longest toe. Then compare the result with the official size chart.

For adults, shoes in sizes 28 to 48 are practical when you want to compare standard collections with sports models. Also pay attention to the last:

  • Narrow or race-oriented last: fits closely and may be suitable for speed training.
  • Standard fit: you will usually order your usual EU size, but always check the product information.
  • Roomier last: provides more space around the forefoot and may feel comfortable for everyday walking.

For children’s shoes, the Geox Spider-Man children’s shoes product information recommends allowing approximately 0.5 to 1 centimetre of extra room. If the foot length falls between two sizes, the larger size is recommended. However, too much room can cause the foot to slide, so also check the heel fastening.

2. Material and care

The material affects how a shoe feels and how much care it requires.

  • Leather: according to the product details, the Puma Speedcat OG consists of 97% leather and 3% textile on the upper. Leather can mould to the foot but requires suitable care.
  • Synthetic material: the Skechers Oak Canyon has a synthetic upper and a rubber sole. This makes it easy to maintain: wipe it with a soft, damp cloth.
  • Textile and mesh: the LI-NING Red Hare 9 models use a BOOM FIBER upper with a woven or mesh-like construction. According to the brand’s product description, this is designed to support ventilation and moisture wicking. Do not machine-wash the shoes unless this is permitted.
  • Combination materials: the Geox children’s shoes combine polyurethane and polyester with a rubber outsole. Do not use an aggressive cleaner on this type of shoe, and allow wet shoes to dry naturally.

Material is also important for babies. The Chicco baby clothing in this selection is made from 100% cotton. Always check the care label and choose clothing sizes based on height or age; clothing sizes such as 068 or 074 are not the same as shoe sizes.

3. Sole, fastening and intended use

For walking in the Netherlands, grip and flexibility are more important than a striking tread pattern. A rubber outsole may be suitable for everyday use, but actual grip also depends on wear, rain and the surface.

Children often put their shoes on independently. A single hook-and-loop fastening with elastic laces, as found on the Geox J Perth B. D, may therefore be more practical than laces alone. A removable insole also makes checking and cleaning easier.

For men’s running shoes, focus primarily on the combination of cushioning, weight, support and fit. According to the product details, the LI-NING Red Hare 9 Pro has a wider base, a dual BOOM midsole and a GCR rubber outsole. The manufacturer describes specific percentages for cushioning, energy return and ventilation; treat these as claims from LI-NING’s product description, not as a universal result for every runner.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure both feet and use the longer measurement. Compare it with the size chart for the specific model. For children’s shoes, you should generally allow 0.5 to 1 centimetre of room for growth, without the heel slipping when walking.

How long do shoes bought online last?

This depends on use, body weight, the surface, care and how you rotate several pairs. Walking shoes worn outdoors every day will wear differently from trainers used occasionally. Check the sole, seams and insole regularly, and allow wet shoes to dry at room temperature.

How much does shoe care cost?

For most synthetic shoes, a soft cloth and mild soapy water are sufficient, provided the product instructions allow this. Leather models may need additional care. With children’s shoes that have ventilation openings, do not use sharp objects and follow the label. Proper care costs very little but helps prevent unnecessary replacement.
