Buying shoes and slippers online: how to choose the right pair without making a costly mistake

Buying shoes and slippers online may seem straightforward, but a product photo doesn’t tell you everything. A sole may look comfortable yet offer little grip. A trainer may match the size chart but feel less comfortable because of its narrow last. Terms such as “durable”, “non-slip” and “comfortable” are only useful when you check the specifications behind them.

Use this practical guide to compare men’s shoes, women’s shoes, casual shoes and unisex slippers based on features that matter for everyday use in the Netherlands.

Common pitfalls when buying shoes online

1. Choosing based only on appearance and brand name

Vans Old Skool trainers, Converse trainers and Puma Speedcat shoes each have a distinctive style. That makes them suitable for casual outfits and streetwear, but style says little about fit, material or grip. So check the last, fastening, insole and sole construction too.

A low-top trainer with a flat sole may be comfortable for short walks or everyday wear, but it won’t necessarily suit every foot or activity. For skateboarding, for example, grip and freedom of movement matter more than appearance alone.

2. Mistaking “non-slip” for guaranteed grip

A treaded sole helps channel away water and dirt, but grip also depends on the surface, wear and moisture. For bathroom slippers, a textured sole with grooves is more practical than a completely flat sole. Even so, you still need to walk carefully on a wet floor.

Also note the difference between an ordinary EVA slipper for home and a model with drainage channels. The latter is designed more specifically for situations where water needs to drain away quickly.

3. Choosing a size without checking your foot length

Size 37, size 38, size 39, size 42 or size 44 can fit differently depending on the brand and model. Slippers with a wide fit offer more room at the forefoot, while a regular-fit trainer will feel different.

Measure your foot towards the end of the day, preferably wearing the socks you usually wear. Then compare the measurement with the product size chart. Some PUXI models, for example, list a recommended foot length for each EU size. This is more useful than relying on your usual shoe size alone.

Which features should you prioritise?

Material and care

EVA is lightweight, water-resistant and easy to rinse clean. It’s often used for EVA slippers, bathroom slippers and styles for home or travel. However, EVA can warp if exposed to high temperatures for a long time. So don’t leave your slippers in direct sunlight or near a heat source.

Trainers are made from materials including textile, cotton, rubber, leather and suede. Textile may feel breathable, but it needs to be cleaned differently from suede. Always check the care instructions. The Vans Old Skool listing, for example, advises against machine washing and high temperatures.

Sole, tread and drainage

Look out for three things:

  • Sole thickness: a thicker sole may offer more cushioning and protection, but it won’t always feel flexible.
  • Tread: deep grooves and a textured surface can help with contact on wet surfaces.
  • Drainage: openings or channels can help water drain away more quickly from bathroom slippers.

The product information for the PUXI Wave Bathroom Slippers mentions a drainage construction, a recessed footbed and a wave-profile sole. These are design features you can check. They don’t guarantee that slipping will be prevented in every situation.

Fit and intended use

Don’t choose only between women’s shoes and men’s shoes; focus on how you’ll use them:

  • Everyday and casual wear: low-top trainers with laces and a rubber sole are easy to style.
  • Streetwear: Converse trainers, Vans Old Skool trainers and Puma Speedcat shoes have a distinctive look.
  • At home: a soft EVA slide with a shaped footbed can be practical.
  • Bathroom or swimming pool: choose a style with drainage and a clearly defined sole tread.
  • Travel and guests: disposable styles are lightweight and individually wrapped, but are intended for single use.

Frequently asked questions about buying shoes and slippers online

How do I find the right shoe size when ordering online?

Measure both feet in millimetres and use the larger measurement. Compare it with the size chart for the specific model. Also check the fit: “regular” and “wide” aren’t the same. The internal length can vary by brand for trainers in size 37, size 38, size 39, size 42 and size 44.

How long do EVA slippers last?

Their lifespan depends on use, wear, sunlight and care. EVA slippers may wear out more quickly with frequent outdoor use than when worn indoors. Rinse off any dirt, leave them to dry at room temperature and store them out of direct sunlight. Check regularly that the tread is still in good condition.

Are bathroom slippers automatically non-slip?

No. Check the shape of the sole, its tread and grooves, and whether it has drainage channels. A product may be described as a non-slip slipper, but its actual grip varies depending on the floor and conditions. So don’t rely on any slipper as a substitute for taking care on a wet surface.
