Buying shoes online: how to choose the right fit, materials and style

Buying shoes online seems simple: choose a style, select your size and place your order. Yet many disappointing purchases are caused by an incorrect fit, unclear size advice or shoes that are not suited to their intended use. This applies to children’s shoes with lights, women’s trainers and lightweight running shoes.

As a Joybuy Product Recommendation Officer, I filter product information according to practical features. Not eye-catching marketing copy, but things you can check: material, fastening, width, sole type, care instructions and sizing advice.

Common pitfalls when buying shoes online

1. Lights get more attention than practical features

Light-up trainers for children and girls’ trainers with lights stand out, but lighting says nothing about fit or care. So make sure you also check:

  • Is there a hook-and-loop fastening, or are there only laces?
  • Is the shoe standard, narrow or wide?
  • Can you switch the light-up sole on and off with a button?
  • Can the shoe be cleaned with water?

Machine washing is discouraged for various Skechers children’s shoes, as the lights and internal components could be damaged. A damp cloth and mild soapy water are therefore the recommended cleaning method.

2. The same size does not always mean the same fit

A European size 37 or 38 can feel different from one style to another. Shoe width also plays a part. In the product information, you may see widths such as D, G or H. This indication should be considered alongside the sizing advice.

Pay particular attention to terms such as:

  • Fits normal: usually choose your usual size.
  • Runs small: you may need a size larger.
  • Runs large: a size smaller may fit better.
  • Standard fit: designed for an average foot shape.
  • Slim version: suitable for a narrower foot.

If you are unsure, measure your foot length in millimetres and compare it with the size chart for the specific style.

3. A casual shoe is used for an activity it was not designed for

Women’s trainers are suitable for everyday use, but not automatically for running. Lightweight running shoes need different features, such as a breathable upper, cushioning and a sole with grip. Trail running shoes are also designed for surfaces such as woodland paths, loose earth and wet stones.

A smooth leisure sole may be less suitable on a wet woodland path. Conversely, a substantial trail sole may feel unnecessarily bulky for everyday use in the city.

Important specifications to check

Fit and fastening

For children, elastic laces combined with hook-and-loop fastening are practical. They make the shoes easier to put on and help keep them secure around the foot. With styles that only have laces, it is important that the knot stays tied.

For adults, slip-ons offer convenience, while laces provide more room for adjustment. Also check the stated shoe width. If you need more room around the forefoot, look for wide slippers or styles available in a wider fit. The PUXI Banana Boat slipper, for example, has a wide shape and is made from EVA.

Upper and lining

Mesh and woven textiles generally allow more air to pass through than synthetic leather. This can be comfortable for everyday use or running. Synthetic materials are often easier to wipe clean and may offer additional structure.

Also check the lining. The Skechers On-The-GO Glacial Ultra has a faux-fur lining and a textile insole. This makes the style more suitable for casual wear in cooler weather than for sporting activities.

Sole and intended surface

A rubber or rubber-like sole can provide grip, but the precise properties vary from one style to another. PELLIOT styles list a ROCKYTEC rubber outsole. According to the product description, it is intended for surfaces including wet stones, mud and loose sand. This is a product specification, not a guarantee of grip in every circumstance.

For school, play and everyday use, flexibility and a simple fastening are often more important than a heavy-tread sole. With light-up shoes, careful cleaning is also essential.

Check size and care before buying

Use this quick checklist when ordering online:

  1. Measure both feet at the end of the day and use the longer foot as your reference.
  2. Compare your foot length with the size chart for the style you have chosen.
  3. Check the width indication and the specific sizing advice.
  4. Look at the fastening: laces, elastic laces, hook-and-loop fastening or slip-on.
  5. Read the care instructions, especially for light-up trainers.
  6. Choose a sole suited to asphalt, the school playground, a sports hall or trails.

Brand claims about comfort, support or durability are not automatically a guarantee for every user. A brand’s own research may mention certain features, but your experience also depends on foot shape, activity and surface. Therefore, focus primarily on the product specifications you can verify.

Frequently asked questions about buying shoes online

How do I know which shoe size to order online?

Measure your foot in millimetres and compare it with the size chart for the style. Also check the fit advice. Some shoes run small or large, even when the nominal European size is the same.

Are light-up shoes suitable for everyday use?

That depends on the construction and care requirements. According to the product descriptions, the Skechers children’s shoes mentioned are intended for everyday use, school and play. Do not automatically put them in the washing machine; follow the instructions for each style.

Which shoes are suitable for running and trail running?

For running, choose a lightweight style with a breathable upper, appropriate cushioning and a sole suited to the surface. For trail running, grip and durability are more important. Also check whether the fit suits a narrow, standard or wider foot.
