Buying shoes without making the wrong choice: how to choose the right size, fit and style

Online shoe shopping may seem simple, but an appealing photo does not tell you everything. A shoe can look comfortable yet feel too narrow, be poorly suited to wet weather or show signs of wear after a short time. With a few checks, you can avoid paying mainly for a brand name, colour or temporary offer.

Common pitfalls when buying shoes

1. Choosing a size without measuring your feet

Sizes vary by brand, model and country. An EU size 42 does not have exactly the same internal length in every model. This is particularly important with children's shoes, where relying solely on age or an old pair of shoes can be risky. Measure both feet in centimetres, then use the size chart for the specific product.

2. Confusing comfort with soft cushioning

A soft insole feels pleasant when you first try it on, but that says little about the fit. Also consider the width, the shape of the toe box, the fastening and the support around the heel. A shoe that pinches at the front does not automatically become suitable just because the sole is soft.

3. Interpreting material claims too broadly

“Leather shoes” may be made entirely from leather, but they may also feature leather details or a combination of leather and synthetic materials. Always check the product specifications. For example, the Nike Air Force 1 Shadow is listed as having a leather upper, while various US POLO ASSN models are described as featuring synthetic leather, mesh or a combination of leather and synthetic material.

Three specifications you should always check

Fit and size

Look at the stated fit: regular, standard or another width measurement. The Skechers D'Lux Walker - Scrambler is listed with a regular fit and shoe width D. The product information recommends ordering your usual size. This is a useful starting point, but measure your foot anyway if you are between sizes.

For children, foot length in centimetres is a useful reference. According to the product information, the Geox B Lightyloo recommends approximately 0.5 to 1 centimetre of extra room for the toes. If the foot length falls between two sizes, the larger size is recommended.

Upper and sole

The upper affects both how the shoe feels and how you care for it:

  • Leather: often retains its shape well, but requires care and should be cleaned according to the product instructions.
  • Synthetic leather: practical for everyday use, but check the composition rather than relying solely on the marketing name.
  • Textile and mesh: can be lightweight and breathable; the Skechers Track Syntac is described as combining leather and mesh.
  • Rubber or EVA: commonly used sole materials with different properties in terms of flexibility, weight and grip.

An FG football boot, such as the Joma Super Copa 2401 FG, is designed for firm natural grass pitches. The stud configuration does not automatically make this type of model suitable for artificial turf, indoor football or soft, muddy ground.

Fastening and everyday use

Laces offer plenty of adjustment, while hook-and-loop fastenings can be quick and practical for children's shoes. The Geox B Lightyloo has a single hook-and-loop fastening with elastic laces. For active children, this can be more convenient than tying loose laces each time.

Adjustable straps are important for sandals. The Birkenstock Arizona has two individually adjustable buckles. The product information lists a cork footbed, an EVA sole and a natural leather upper. When buying, also check the stated width and foot length.

How this product avoids the pitfall

Synthetic leather and mesh upper, rubber sole and removable insole.

Care for longer-lasting wear

Good shoe care starts with using the right method for the material. For leather shoes, use a suitable neutral cream or shoe polish and test it first on an inconspicuous area. Any water-repellent spray should be suitable for the type of leather.

For textile, mesh and synthetic materials, product descriptions from brands including Skechers and Geox recommend using a soft, damp cloth. Avoid submerging shoes in water, bleach, harsh chemicals and the washing machine unless explicitly permitted. Allow shoes to dry at room temperature, away from direct heat. A JORDAN&JUDY Horsehair Shoe Shine Brush 4-Piece Set may be suitable for gently removing dust from leather shoes; do check that the brush is suitable for the finish.

If you are looking to buy trainers, you can compare Converse shoes with models from Skechers, Geox, Nike and US POLO ASSN. For men's shoes and women's shoes, the material, size and intended use matter more than colour alone. With sandals, pay particular attention to adjustability and foot width.

Frequently asked questions about buying shoes

How do I measure my foot for online shoes?

Place your foot on a sheet of paper, hold the pen upright and measure from the heel to the tip of your longest toe. Measure both feet and use the longer measurement. Compare this value with the size chart for the model you have chosen, rather than relying solely on your usual EU size.

How long do shoes typically last?

This depends on the material, how often they are worn, the surface and how well they are cared for. Trainers worn every day may wear out more quickly than shoes that are alternated. Allow shoes to dry fully, alternate between pairs where possible and only use each model on the surface it is designed for.

Are more expensive shoes automatically more comfortable?

No. Price is not a direct measure of fit. Check the materials, width, fastening, sole and returns policy. A more affordable model that fits your foot and intended use well may be more practical than a more expensive model with the wrong shape.
