How to buy shoes without getting it wrong: choosing the right size, sole and fit

Buying shoes seems straightforward, until a few weeks later when you develop a sore, cramped forefoot, slippery soles or materials that wear out quickly. Photos and marketing copy alone are rarely enough to help you make the right choice, especially when shopping online. A style might look great but still be unsuitable for long walks, rainy bike rides or everyday wear at school.

Focus on the features that matter for how you’ll use the shoes. Here are some practical points to consider when choosing men’s shoes, women’s shoes, children’s shoes, trainers, sports shoes and walking shoes.

Three common pitfalls when buying shoes

1. Looking only at the appearance

A retro trainer, skate shoe or casual shoe might go well with your clothes, but that tells you little about its fit and support. A flat rubber sole might be suitable for short trips around town, while walking or running calls for more cushioning and a sole suited to the terrain.

2. Comparing sizes without measurements

An EU size isn’t exactly the same across every brand. Width, toe room and the shape of the last also vary. So don’t automatically order the same size as another pair you own. Measure your feet at the end of the day and check the product’s size chart. It’s particularly important to check children’s shoes carefully: feet grow quickly, and a shoe that’s too tight can become uncomfortable.

3. Treating “waterproof”, “grip” and “comfort” as guarantees

These terms are sometimes used quite broadly. Check which materials and construction details are actually specified. A water-repellent nubuck upper isn’t the same as a fully waterproof membrane construction. And a shoe with a treaded sole isn’t automatically suitable for wet tiles, mud or technical trails.

Which features should you check?

1. Fit, size and fastening

Look for:

  • the stated EU size and any foot length in millimetres;
  • the stated width, such as standard or D;
  • the shape of the toe and the amount of room available;
  • the type of fastening: laces, hook-and-loop or a quick-lacing system;
  • a removable insole, if you need one.

Product details are particularly useful for larger sizes. For example, the range includes size 47.5 styles such as the Skechers Track-Ripkent and New Balance U1906WFD. The Vans Knu Skool is available in sizes including 41 and 44.5. Always check the exact version on the product page.

2. Sole, cushioning and grip

The midsole plays a big part in how a shoe feels when you’re walking or exercising. EVA foam is often used for its light weight and cushioning properties. For example, the New Balance U2002RCE lists a combination of ABZORB and N-ergy technologies in its midsole. A lightweight EVA midsole is also specified for children’s shoes such as the New Balance PC574EVN.

For running shoes, trail running shoes and sports shoes, also look at:

  • the thickness and composition of the midsole;
  • forefoot flexibility;
  • the tread and rubber compound of the outsole;
  • reinforcements around the toe and heel;
  • stability on the terrain you’re buying the shoes for.

A sole with deep grooves can be useful on loose or muddy ground. For everyday wear in town, a simpler tread is often enough.

3. Upper material and care

Mesh and textile uppers generally offer breathability, while synthetic overlays or nubuck can add structure. Leather and nubuck need different care from mesh, though. Where possible, follow the cleaning instructions in the product information. Many styles shouldn’t be machine-washed and should be left to air-dry, away from direct heat.

For waterproof shoes, check whether a membrane is specified. The Salomon XA Pro 3D v9 GTX lists a GORE-TEX membrane. The Nike Manoa is described as water-repellent, with a nubuck leather upper. These are different product features, so you shouldn’t assess both styles in the same way.

Extra tips for different types of shoes

  • Running shoes: choose a style with cushioning to suit your needs, a secure heel fit and an upper that’s right for your training environment.
  • Trail running shoes: look at the tread, grip, toe protection and stability. Salomon trail shoes and styles from Joma or PELLIOT are described with these features in mind.
  • Walking shoes: check the ankle height, sole construction and water-repellent or waterproof features.
  • Casual shoes and trainers: consider the material, insole and comfort for everyday wear. New Balance shoes, Vans trainers and Skechers shoes vary considerably in shape and intended use.
  • Shower slides: a drainage design and a shoe with an anti-slip tread can be useful in the bathroom. The PUXI Wave lists EVA, drainage channels and a grooved sole.
  • Children’s shoes: choose a fastening your child can manage themselves and check the size more often than you would for an adult.

Frequently asked questions about buying shoes

How do I find the right shoe size online?

Measure both feet in millimetres while standing and use the measurement of your longer foot. Compare it with the chart on the product page. Allow for socks and intended use: walking shoes are sometimes worn with thicker socks.

How long do shoes last on average?

It depends on the material, distance walked, body weight, surface and care. Look for cracks in the upper, worn-smooth tread and a compressed midsole. Alternating between two pairs can give the materials time to air between wears, but it doesn’t replace checking for wear and tear.

Are more expensive shoes always more comfortable?

Not necessarily. Comfort depends mainly on fit, size, sole and how you’ll use the shoes. A trail running shoe may feel unnecessarily stiff for everyday wear around town, while a lightweight trainer may not offer enough grip on muddy paths. So compare the specifications with how you plan to use them.
