Buying shoes without regrets: how to choose trainers, running shoes and children’s shoes

Buying shoes seems simple until a pair starts rubbing after a few weeks, offers insufficient grip or turns out not to be suitable for its intended use. Online, you often see terms such as “lightweight”, “extra comfort” and “breathable”. These descriptions only really tell you something when you also check the specific product details.

In this buying guide from the Joybuy Product Recommendation Officer, you’ll learn what to look for in trainers, running shoes, women’s trainers, men’s trainers and children’s shoes. This allows you to compare models based on fit, material, fastening and sole, rather than just appearance or brand name.

Three common pitfalls when buying shoes

1. Mistaking a comfortable sole for the right fit

A soft insole feels pleasant when trying shoes on, but it won’t correct the wrong size or width. So check the stated fit, shoe width and sizing advice. A model with Memory Foam may provide extra cushioning, but it will still be unsuitable if your foot slides forwards or your toes don’t have enough room.

2. Using trainers for an activity they weren’t designed for

Casual trainers are intended for everyday use. Running shoes generally have a different midsole and outsole, designed to cope with repeated steps while running. A fashionable trainer is therefore not automatically suitable for running, long walks or intensive training.

3. Judging “grip” without looking at the sole

Marketing copy sometimes mentions good grip, but you should also check the material and tread pattern of the outsole. A flat rubber sole may be suitable for the city, while a sole with lugs is better suited to unpaved paths. According to adidas’s own product information, the Adiwear outsole offers grip and durability; this is a product specification, not a guarantee for every surface or weather condition.

Important specifications to check

Fit, size and foot length

When ordering online, don’t just compare your usual EU size. Also check the stated foot length in millimetres or centimetres and read the sizing advice. This is particularly important when comparing different brands, such as Skechers shoes, PUMA trainers and adidas running shoes.

Also look out for:

  • Shoe width: for example, D, G or a standard width.
  • Fastening: laces offer adjustability; hook-and-loop fastenings are practical for children.
  • Toe room: a round toe may offer more space than a narrow, streamlined shape.
  • Fit advice: some models fit true to size, while others come up large or small.

For example, the Skechers Graceful model is described as coming up large, with one size smaller recommended. This differs from models that, according to the product information, fit normally or true to size.

Upper and ventilation

A mesh or textile upper may feel more breathable than synthetic leather. This can make a model suitable for everyday use in warmer weather, but it doesn’t automatically say anything about water resistance. So check whether the description mentions a specific finish.

For breathable summer trainers, you can also browse the wider category via the breathable summer trainers range.

Midsole and outsole

The midsole affects how a shoe feels under your foot. Product information may mention IMEVA, EVA, Bounce 2.0, Cloudfoam and Dreamstrike. These are brand-specific materials or names. According to PUMA’s own information, IMEVA is designed to provide a lightweight, comfortable feel. According to adidas’s own information, Bounce 2.0 and Cloudfoam are designed for cushioning and comfort.

Also look at the outsole:

  • Rubber: often chosen for grip and durability.
  • Treaded sole: can provide more support on uneven ground.
  • Flat sole: generally more suitable for casual use and smooth urban surfaces.
  • Lugs or deeper tread: relevant for sports shoes and some walking shoes.

Choosing shoes for women, men and children

For women’s trainers and men’s trainers, material, width and everyday use are often decisive factors. A textile or mesh model may be comfortable for commuting, while synthetic leather may be easier to wipe clean. For children’s shoes, a practical fastening, sufficient toe room and the right size are particularly important. Hook-and-loop models, such as some Skechers children’s trainers, are quick to put on and take off.

For walking or longer distances, check the sole as well as comfort. Anyone who mainly walks on tarmac will generally need different features from someone who uses unpaved paths. For every pair, check the full product information, care advice and available sizes.

Frequently asked questions about buying shoes

How do I determine my shoe size when buying online?

Measure your foot at the end of the day while wearing the socks you intend to wear with the shoes. Compare the longer foot with the product’s size chart. Also check the stated width and specific sizing advice; an EU size is not identical across every brand.

How long do trainers and running shoes last?

Their lifespan depends on use, surface, body weight, care and material. Look out for visible wear on the outsole, cracks in the upper and a midsole that no longer feels even underfoot. If you run intensively, replacing your shoes in good time is more important than when they’re used casually from time to time.

Can I wear running shoes every day?

You can, provided the fit and appearance suit how you intend to use them. Bear in mind that running shoes are designed for a specific running motion and surface. For everyday use, casual trainers or comfortable shoes may be more practical. Always check the product description before using a pair for a different activity.
