Buying shoes online: how to choose a pair that fits without making a mistake

Buying shoes online seems straightforward: pick a style, select your size and place your order. Yet many purchases go wrong because of information that's missing or presented too vaguely. A shoe that looks comfortable might, for example, have a narrow last. And a model with a treaded sole isn't automatically suitable for wet walking paths.

So pay particular attention to these common pitfalls:

  • Choosing based only on looks and brand name: Skechers shoes, Salomon shoes or PUMA trainers can have very different fits and intended uses.
  • Confusing comfort with cushioning: a soft insole says little about the width, support or stability of the whole shoe.
  • Confusing water-repellent with waterproof: check whether the product description actually mentions a waterproof membrane, such as GORE-TEX.
  • Ordering your size without further checks: a normal fit, width D or G can feel different from one model to another. Always check the size guide and the returns policy.

What to look for when buying shoes online

1. Fit, width and internal space

The right size is more than just the European number. Also look at:

  • the stated fit, for example normal or narrow;
  • the shoe width, such as D or G;
  • the shape of the toe;
  • the room for your toes;
  • the possibility of wearing thicker socks.

A rounded toe generally offers more wiggle room than a narrow, pointed one. For children's shoes, a secure fastening is important. Velcro, as found on certain Skechers children's shoes, makes it easier for little ones to put them on independently. With running shoes, a slightly roomier toe box can be welcome, especially when feet swell during longer exertion. Always check the specific size information for the model.

2. Sole and grip matched to your use

The sole partly determines how a shoe feels and what surface it's suited for.

  • Rubber outsoles are common on trainers, men's shoes and women's shoes, offering practical durability for everyday wear.
  • A treaded sole can provide extra grip on uneven ground, but the tread pattern and rubber compound remain the deciding factors.
  • For running shoes and trail running shoes, cushioning, stability and traction are relevant points.
  • With walking boots or shoes with good grip, it's wise to consider the type of terrain: tarmac, gravel, mud or rocky paths.

According to the product description of the Salomon DRX DEFY GRVL, this model features an Active Chassis, Energy Foam midsole and All Terrain Contagrip outsole. Those specifications suit gravel and mixed terrain, but they don't automatically make the shoe suitable for every activity.

3. Material, care and protection against moisture

The upper affects breathability, care and lifespan. Textile and mesh can be airy, while synthetic materials are often easy to clean with a damp cloth. Nubuck requires care suitable for leather-like materials.

Pay attention to the difference between these terms:

  • Water-repellent: the outer surface can temporarily resist light rain or splashes.
  • Waterproof: the construction includes an explicitly stated waterproof layer or membrane.
  • Breathable: a mesh or textile upper can let air through, but that doesn't mean the shoe is waterproof.

The Nike Manoa is described in the product information as water-repellent and has a nubuck leather upper with a rubber sole. The Salomon XA Pro 3D v9 GTX, on the other hand, mentions a GORE-TEX membrane. Use this information as a product specification, not as a guarantee that your feet will stay dry in all conditions.

How to check your order before you buy

Use this short checklist when you buy shoes online:

  1. Measure both feet at the end of the day and compare the longest foot with the size guide.
  2. Check whether the shoe is suitable for everyday wear, sport, running, walking or trail running.
  3. Examine the upper, lining, insole and sole separately.
  4. Look for concrete information about waterproofing, grip and fastening.
  5. Check whether the insole is removable if you use your own orthotics.
  6. Read the care instructions. Not every model can go in the washing machine.
  7. Keep your order confirmation and product information. Within the EU, many consumer products come with a statutory guarantee; your exact rights depend on the situation and applicable rules.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure your foot in centimetres while standing and compare that length with the size guide for the specific model. Also look at width and fit. A size 42 with width D can feel different from a size 42 with width G.

How long do shoes bought online last?

That depends on the material, how often you wear them, your body weight, the surface and how you care for them. A pair worn every day will generally wear differently from shoes you rotate. Let shoes dry at room temperature and follow the manufacturer's care instructions.

Are more expensive shoes automatically more comfortable?

No. Price and comfort are not the same thing. Instead, compare the fit, sole, cushioning, fastening, materials and intended use. A simple trainer can be fine for everyday wear, while a technical model only offers an advantage when you're actually walking on gravel, trails or wet terrain.
