Buying shoes and trainers online: how to choose a pair that suits you

Buying shoes and trainers online seems straightforward until you have to choose between women’s shoes, men’s shoes, children’s shoes, trainers, casual shoes and sports shoes. A photo tells you little about the fit, while terms such as “comfortable” or “durable” are not always specific enough. With the right checks, you can avoid a disappointing purchase and compare products based on the features that really matter in the UK.

Common pitfalls when buying shoes online

1. Relying solely on the EU size

A size 37 shoe from one brand may fit differently from a size 37 model from another. The width, toe shape and thickness of the lining can also affect the fit. Always check the size chart, the stated fit and any information such as “true to size”.

If you are unsure, foot length in centimetres is a useful additional check. For children’s shoes, also allow room for growth without the heel slipping out of the shoe while walking.

2. Overlooking materials and care

Canvas, mesh, suede, synthetic leather and Croslite all have different properties. A breathable upper can be comfortable for everyday wear, but it often requires different care from a rubber or synthetic shoe. Also check whether the shoes are machine washable. For various models, cleaning with a damp cloth and leaving them to dry naturally is specifically recommended.

A shoe that you wear outdoors frequently will also benefit more from a treaded sole than a smooth sole. Browse our range of shoes with rubber soles if grip and easy everyday care are important to you.

3. Choosing a model for the wrong activity

Casual shoes are not automatically suitable for running. Trail running shoes are designed with different features from trainers made for the city. For example, the product description for the Nike Huarache 9 Varsity Lax FG states that this model is intended for lacrosse on natural grass and has an FG stud configuration. That does not automatically make it suitable for walking on pavements.

First decide where you will wear the shoes: at school, to work, during a walk, on a sports pitch or on uneven ground.

Three specifications you should always check

Fit, size and fastening

As well as the EU size, look at:

  • the stated width, such as standard or D;
  • the shape of the toe box;
  • laces, hook-and-loop fastening or a slip-on design;
  • the foot length range shown in the size chart;
  • room for socks and any orthotic insoles.

Examples from the range include size 37-38 in the Crocs Baya Platform Lined Clog, size 40 in the Nike lacrosse shoes and size 45 in the Lacoste L003 2K24. These sizes cannot be compared directly without checking the specific size chart.

Sole and intended use

The sole plays an important part in how a shoe feels and what it is designed for. A rubber outsole can be practical for everyday use. A treaded sole is useful when you need extra grip. With walking shoes and trail running shoes, you should also consider stability, toe protection and the type of terrain.

The Salomon XA Pro 3D v9 GTX product information mentions a GORE-TEX membrane, Quicklace fastening and a Contagrip rubber outsole. According to the product description, the model is designed for trail running and walking. Use this information to compare it with your own routes and weather conditions; no shoe automatically makes every type of terrain suitable.

Upper, lining and care

A mesh upper may feel more breathable, while suede or synthetic leather offers a different look and has different care requirements. According to the product details, the Vans Old Skool UA has a textile upper, textile lining and rubber sole. The Vans Hylane combines suede, synthetic material and textile, according to its description.

For products containing animal-derived components, also check the relevant statement. The listed Vans models state that non-textile parts of animal origin may be present.

Looking for more options?

We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.

Other models to compare

If you are mainly looking for an everyday trainer, you could also consider the Vans trainers UA Old Skool or Hylane, the Converse trainers Star Player 76 OX and Chuck Taylor All Star HI, or Skechers shoes such as the Burns and On-The-GO Glacial Ultra. For a sporty look, the Lacoste L003 2K24 and US POLO ASSN trainers are options with a standard width and rubber sole according to the product information.

When choosing men’s shoes in larger sizes, such as size 45 or 46, pay particular attention to the size chart and available width. For women’s shoes in size 37 and lined models, such as some Crocs clogs or lined Skechers boots, it is worth allowing for socks and extra material around the foot.

Frequently asked questions

How do I determine my size when buying shoes online?

Measure both feet from the heel to the longest toe, preferably at the end of the day. Use the measurement of your longer foot and compare it with the brand’s size chart. Also consider the fit: “regular” does not mean that every model has the same amount of internal space.

How long do shoes bought online last?

That depends on use, surface, material, care and fit. Wearing shoes on tarmac every day puts different demands on the sole than occasional indoor use. Store shoes in a dry place, allow moisture to evaporate naturally and follow the care label. Products covered by a legal guarantee are also subject to the applicable European consumer protection rules; various models state a minimum legal guarantee of two years.

Are trainers suitable for walking and sport?

Casual trainers can be suitable for short walks, but running, trail running and field sports have different requirements. Check the sole tread, cushioning, fastening and stated intended use. For example, a Nike lacrosse shoe with FG studs is designed for a sports pitch and is not automatically suitable for everyday walking.
