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

Buying shoes online seems simple until your order arrives. The colour looks different from the product photo, the size fits differently than expected or the sole turns out to be unsuitable for how you plan to use them. A few targeted checks can significantly reduce the chance of making the wrong choice.

This applies to men’s, women’s and children’s shoes, as well as trainers, casual shoes, sports shoes, running shoes and trail running shoes. The right choice depends not just on the brand or appearance, but above all on fit, material and the surface you’ll be using them on.

Three common pitfalls when buying shoes online

1. Assuming a familiar brand means it’s the right shoe

A brand name doesn’t automatically mean a model is right for your needs. Vans trainers can work well with a casual outfit, but they don’t have the same construction as running shoes. A fashionable trainer isn’t necessarily suitable for long walks either.

So start by thinking about how you’ll use them:

  • daily commuting;
  • walking on paved roads;
  • running on tarmac;
  • trail running on muddy, sandy or rocky paths;
  • children’s play and activities;
  • easy to put on and take off at home or on the go.

2. Looking only at the EU size

A size 39 or 44 is a useful starting point, but it doesn’t guarantee a good fit. The shape of the toe, the width of the last and the room around the toes vary from one model to another. Children’s feet also grow quickly.

If possible, measure your feet at the end of the day, wearing the socks you plan to wear with the shoes. Then compare the measurement with the product’s size chart. For children’s shoes, Geox product information recommends allowing around 0.5 to 1 centimetre of growing room and choosing a size up if you’re unsure.

3. Not checking what marketing terms actually mean

Terms such as ‘breathable’, ‘comfortable’ or ‘lightweight’ are only useful if you know what they’re based on. So check the details:

  • Is the upper made from mesh, leather, synthetic material or a combination?
  • Is the sole made from rubber, EVA or another material?
  • Do the shoes have laces, hook-and-loop fastenings or a slip-on design?
  • Is there a specific size and fit chart?
  • Are care instructions and material information available?

For example, according to PUMA’s product description, the Speedcat OG has a leather upper, textile lining, rubber midsole and rubber outsole. These are details you can check; descriptions of comfort and style reflect the brand’s positioning.

The key specifications to compare

Fit and available sizes

Look beyond the length. A regular fit isn’t the same as a wide fit. Pelliot lists some running models in both a standard version and a slim-fit version. This may matter if you have narrower feet.

Also check that the product page actually offers your size. A model may be available in different sizes and colours, but stock can vary by colour. For children’s shoes, double EU sizes such as 20-21 or 23-24 are common for certain clogs.

Sole and surface

The outsole largely determines how a shoe performs on different surfaces. A flat rubber sole is often enough for everyday use. Grip, tread and cushioning are more important for running and trail running shoes.

According to the product information, the Pelliot models in this selection use an EVA midsole and a ROCKYTEC rubber outsole. Some versions also mention Vibram Megagrip. Always check that the specification applies to the exact version you’ve chosen, rather than just another version in the same product range.

Material, fastening and care

According to the product description, a mesh upper can help with airflow, but it often needs more attention when it gets dirty. Leather may need different care from synthetic material. Don’t automatically put shoes in the washing machine: follow the care label.

For children, a simple fastening is practical. According to the product information, the Geox B Lightyloo has a single hook-and-loop fastening combined with elastic laces. Crocs clogs have a slip-on design and are made from 100% Croslite, according to the product description. That makes them practical for short periods at home or during leisure time, but an open clog style isn’t suitable for every walking or sporting activity.

Frequently asked questions about buying shoes online

How do I work out my shoe size when ordering online?

Measure both feet in centimetres and use the measurement for your longer foot. Compare it with the size chart for the specific model. Also check the stated fit and the room around the toes. Growing room is important for children, but too much extra space can reduce stability.

How long do shoes bought online last?

Their lifespan depends on the material, how often you wear them, your body weight, the surface and how well you care for them. A casual trainer worn around town will be used differently from a sports shoe or trail running shoe. Check the soles regularly for wear and follow the care instructions. If a fault isn’t caused by normal wear and tear, your statutory consumer rights in the EU apply; some product pages state a two-year legal guarantee.

How much does it cost to care for shoes bought online?

Costs are usually limited to cleaning products, a soft brush or cloth and, if needed, a waterproofing product suitable for the material. Leather, mesh and synthetic materials don’t all need the same care. So check the care label first and avoid products that could damage the colour or adhesive.
