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

Buying shoes online seems simple: choose a style, select your size and place your order. Yet many purchases end in disappointment. A shoe may look appealing but be unsuitable for long walks, running or everyday wear. Checking the fit, materials and sole carefully can help you avoid making the wrong choice.

Common pitfalls when buying shoes online

1. Mistaking a well-known name for the right shoe

Nike Dunk Low, New Balance trainers, PUMA trainers and Vans trainers are popular choices, but popularity does not automatically mean a shoe is suitable for your needs. A low-profile casual trainer with a rubber sole may be perfectly suitable for the city, but it may lack the cushioning, support or grip you need for running or walking.

So look at what you intend to use the shoes for first, and only then consider the brand or model. Women's shoes, men's shoes and unisex shoes also differ in more than just appearance. The last, available sizes and fit can vary from one model to another.

2. Looking only at the EU size

An EU size is not exactly the same for every brand. The shape of the toe box, the width of the last and the thickness of the lining can also affect the fit. Always check the size guide and compare it with your foot length in millimetres or centimetres.

Pay attention to when you measure your feet, too. Ideally, do it at the end of the day and wear the socks you would normally wear with the shoes. For sports shoes or running shoes, a little extra room around the toes is useful, while a casual shoe can often fit more closely.

3. Failing to turn marketing language into concrete features

Terms such as “lightweight”, “grip” and “comfortable” are only useful when it is clear what they are based on. Look for verifiable information such as:

  • the upper material;
  • the type of midsole;
  • the material and tread pattern of the outsole;
  • the fastening and adjustability;
  • the available sizes and fits;
  • the recommended cleaning method.

When a brand describes a particular performance benefit, we do not treat it as an independently proven result. For example, PELLIOT’s product description states that the EVA midsole provides shock absorption and resilience. That is a product specification from the listing, not a medical guarantee.

The key features to compare

Fit and sizing

A good fit starts with foot length, but it does not end there. If you have narrow feet, check whether a slim fit is available. For regular or wider feet, a standard model may fit better. Adjustable straps or a wide shape are useful for sandals and flip-flops, as your foot is less enclosed.

Also check whether the model has a regular fit and whether the seller recommends choosing your usual size. If you are unsure, the size guide is more important than the size you wear in another brand.

Upper and ventilation

Mesh and textile generally allow more air through than fully enclosed materials. This can be comfortable for sports shoes, trainers and everyday summer wear. Leather and synthetic overlays can add structure and improve durability, but they often require different care.

An online product detail such as “unlined” does not mean that the shoe will be comfortable for everyone. It may improve airflow, but it may also feel different on sensitive feet. That is why you should also read the care instructions and customer reviews where available.

Midsole and outsole

The midsole largely determines how a shoe feels underfoot. EVA is widely used in running shoes and sports shoes because of its low weight and cushioning properties, as described by the manufacturer. In casual shoes, the midsole may be thinner, with greater emphasis on flexibility and appearance.

The outsole should suit the surface you will be walking or running on:

  • Rubber with tread: suitable for everyday use and a range of paved surfaces.
  • Trail or all-terrain tread: designed for gravel, mud, loose ground and uneven paths.
  • Smoother, flat sole: suits lifestyle models, but is less suited to rough ground.
  • EVA outsole: often lightweight and practical for flip-flops, but not the same as a sturdy rubber walking-shoe sole.

Bear in mind that grip claims may come from the brand’s product description. Assess them alongside the visible tread pattern, the material and how you plan to use the shoes.

Check this before you order

  1. Measure both feet and use the size guide for the specific model.
  2. Decide whether you need shoes for running, trail running, walking, work or casual wear.
  3. Check that the sole is suitable for asphalt, gravel, woodland paths or mainly indoor use.
  4. Read the material and care instructions. Some models must not be put in a washing machine or tumble dryer.
  5. Check the returns policy, delivery details, seller information and statutory guarantee. In the EU, many consumer products are covered by statutory conformity protection; the exact rights depend on the circumstances and applicable regulations.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure your foot length while standing upright and compare your longer foot with the model’s size guide. Also check the stated fit, such as slim fit, regular fit or wide fit. A brand’s size designation is not always directly comparable with that of another brand.

Which shoes are suitable for everyday walking?

For everyday walking on paved roads, casual shoes or trainers with a secure fit, sufficient flexibility and a rubber sole are often practical. For woodland paths, mud or gravel, walking shoes or trail-running shoes with a more pronounced tread are a more logical choice. Always check the product specifications rather than relying solely on the model name.

How long do shoes last on average?

Their lifespan depends on how often they are worn, your body weight, the surface, the materials and how well they are cared for. A pair worn every day will generally wear out faster than shoes that are alternated. After a wet walk, allow your shoes to air-dry naturally, avoid direct heat and follow the care label. This will help keep the materials and sole in usable condition for longer.
