Buying shoes online: how to choose a pair that suits the way you use them

Buying shoes online seems simple: choose a brand, select your size and place your order. But a style that looks appealing can disappoint in practice. The sole may not offer enough grip, a trainer may come up narrower than expected, or a water-repellent style may be mistaken for a fully waterproof shoe.

Use this practical checklist to compare women’s shoes, men’s shoes, unisex shoes, trainers and sports shoes based on the features that really matter. Then discover some popular options for everyday wear, sport and outdoor activities.

Common pitfalls when buying shoes online

1. Focusing only on how they look

A trendy style isn’t automatically suitable for long walks or running. A flat rubber sole may be comfortable for casual wear, but might not offer enough cushioning for intensive training. So start by thinking about how you’ll use them: for work, around town, walking, running or trail running.

2. Choosing a size without checking

An EU size isn’t exactly the same across every brand. Width, the shoe’s last and the lining can also affect the fit. Check the size chart and compare the stated foot length with your own measurements. Pay particular attention to specific sizes, such as size 36 shoes, size 38 shoes or size 42 shoes.

Measure your foot at the end of the day, wearing the socks you usually wear. Measure both feet and use the longer measurement. For walking shoes or trail running shoes, a little extra room around the toes can be helpful, while a casual trainer can often fit more snugly.

3. Taking marketing claims at face value

Terms such as “comfortable”, “breathable” and “waterproof” only tell you so much when the specifications behind them aren’t clear. A mesh upper may help with ventilation, according to the product description, but it’s not the same as a membrane construction. With GORE-TEX shoes, you should also consider the sole, fastening and care instructions.

Always check who is making the claim. We don’t present a statement about performance as established fact when it comes only from the brand or product description. According to Salomon’s product information, a GORE-TEX membrane is designed to offer water resistance and breathability; your conditions of use and how you care for the shoes still matter.

Which features should you prioritise?

1. Fit and sizing

The most important specifications are:

  • EU size and available half sizes
  • stated foot length in millimetres or centimetres;
  • width or fit, such as regular, narrow or wide;
  • type of fastening: laces, Quicklace, buckle or slip-on;
  • room around the toes and support around the heel.

A shoe that feels comfortable when you try it on can still cause pressure points after prolonged wear. With styles that have a lined interior, such as some women’s boots or Crocs clogs, the amount of available space can feel different from that of a lightly lined trainer.

2. Sole, cushioning and grip

For everyday wear, rubber soles and a suitable tread are often more important than a striking colour detail. Look out for the difference between:

  • a flat tread for town and casual wear;
  • a chunkier tread for walking;
  • deep lugs for soft or muddy trails;
  • a cushioned midsole for running and sports shoes.

The PELLIOT running shoe’s product description lists an EVA midsole and a ROCKYTEC outsole for cushioning and grip. On paper, that makes the style suitable for use on different surfaces, but your running style and terrain will determine whether it’s the right choice.

3. Materials and care

Leather, mesh, synthetic materials and CROSLITE all have different care requirements. Leather generally needs a suitable care product and shouldn’t be fully submerged. According to several product descriptions, you can clean mesh and synthetic panels with a soft brush or damp cloth. Machine washing is not recommended for various styles.

Also check the product’s origin, manufacturer details and warranty information. Several of the styles mentioned list a legal guarantee of at least two years under EU consumer law. Your exact rights may depend on the national legislation that applies.

Other styles to compare

If style is your main priority, take a look at Nike Dunk Low, Vans Knu Skool, Vans Old Skool or Puma styles. For colder days, Skechers On-The-GO boots and women’s boots are practical options to explore. If you’re looking for a leather style, take a look at the Geox Women D Bleyze E Collection. For running and trail running, the PELLIOT shoe, Nike Pegasus Trail 3 and Salomon Speedcross styles are more suitable than a standard lifestyle trainer.

Use filters for brand, size, colour, material and intended use. This will help you find shoes by brand more quickly and avoid choosing a style based on the photo alone.

Frequently asked questions

What size should I choose when ordering shoes online?

Use the size chart for the specific style and compare it with your measured foot length. Check the stated fit, too. A size 38 from one brand may fit differently from a size 38 from another. If you’re between sizes, the shoe’s construction and intended use can help you decide.

Are GORE-TEX shoes fully waterproof?

According to the product descriptions for the Salomon styles mentioned, a GORE-TEX membrane helps provide water resistance and breathability. That doesn’t mean you should assume every shoe is waterproof in all conditions. Seams, the tongue, fastening, wear and care can all affect how well the shoes keep water out.

How long do shoes last?

Their lifespan depends on the distance you walk, the surface, your body weight, how often you wear them, the materials and how you care for them. Let your shoes dry thoroughly after use, keep them away from direct heat and follow the washing or care advice on the label. Replace a pair when the sole becomes visibly smooth, the cushioning noticeably deteriorates or the fit no longer feels stable.
