Buying shoes online: how to choose the right fit and style

Ordering shoes online is convenient, but an attractive photo does not always tell you everything. Problems with men’s shoes, children’s shoes and trainers often only become apparent after several days of wear. A narrow fit can pinch, a sole may not be suitable for how you plan to use the shoes, and children’s feet can grow faster than expected.

Use these practical checks to compare models based on their specifications rather than just their colour or brand name.

Common pitfalls when buying shoes online

1. Confusing a fashionable shape with everyday comfort

A very slim model may look stylish, but it may offer less room around the forefoot. For example, the Puma Speedcat trainers have an ultra-slim silhouette. This works well with casual outfits, but if you have wide feet, always check the size guide and foot length. According to the product information, this model has standard sizing; the stated EU size 42 is suitable for a foot length of 27 cm.

2. Choosing running shoes without considering how you will use them

Running shoes, racing shoes and comfortable sports shoes do not automatically have the same properties. A racing shoe with a firm plate and close-fitting last may be suitable for intensive training, but less comfortable for relaxed walking or standing for long periods. So look at the midsole, fit and terrain the model is designed for.

3. Buying children’s shoes based on age rather than foot length

Age indications are only a guide. Measure both feet while your child is standing and compare the longer foot with the size guide. For the Geox J Perth B. D model, the product information recommends approximately 0.5 to 1 cm of extra room for the toes. If the foot length falls between two sizes, the product information recommends considering the larger size.

Which specifications should you check?

Fit, size and toe room

Do not look only at the EU size. Also check:

  • the stated foot length in centimetres;
  • the shoe width, such as width D;
  • the shape of the toe box;
  • the type of fastening;
  • the room needed for socks and movement.

A model with hook-and-loop fastening, such as some children’s trainers with hook-and-loop straps, can be practical when children are putting their shoes on and taking them off independently. However, check that the strap secures the foot properly without creating pressure points.

Materials and ventilation

A leather upper feels different from synthetic material. According to the product information, the Puma Speedcat consists of 97% leather and 3% textile on the outside, with a rubber outsole. This makes it important to follow the care instructions and not simply put the shoes in the washing machine.

For children’s shoes, a combination of synthetic material and textile can be practical for everyday use. According to the product description, the Geox J Perth B. D has an upper made from 70% polyurethane and 30% polyester, a rubber sole and a removable insole. The manufacturer describes Geox Respira technology as a construction featuring a perforated sole and breathable membrane. This is a brand claim about how the technology works, so also assess the construction, care requirements and your child’s needs.

Sole, cushioning and terrain

For walking shoes and everyday trainers, grip, flexibility and stability are important things to check. According to the product information, the Skechers Oak Canyon Redwick has a synthetic upper, rubber outsole, padded collar and memory foam insole. The stated fit is standard with width D.

Different properties are relevant for racing shoes. According to the product description, the LI-NING Red Hare 9 models use a BOOM midsole, woven BOOM FIBER upper and rubber outsole. The Ultra version also includes a fibreglass plate. According to LI-NING’s own product information, the last is race-oriented and close-fitting. If you prefer more room around the toes or wear thicker sports socks, that information suggests considering half a size larger.

Please note: technical percentages relating to cushioning, stability or grip are claims made in the brand’s product description. Treat them as product specifications, not as a guarantee of a particular sporting performance or physical result.

Frequently asked questions about buying shoes online

How do I determine my shoe size when ordering online?

Measure your foot at the end of the day, wearing the socks you normally wear. Record the length of your longer foot and compare it with the product’s size guide. Also consider the width and fit. Children’s shoes need extra room, but too much room can also cause the foot to slide around.

How long do shoes bought online last?

Their lifespan depends on use, the surface they are worn on, body weight, care and materials. A casual trainer for everyday use wears differently from racing shoes used for intensive training. Rotate your shoes, allow wet shoes to dry naturally and follow the care instructions. Check the outsole, seams and insole regularly.

Are more expensive trainers automatically more comfortable?

No. Comfort mainly depends on the right size, last, sole and intended use. A technical running model may be unnecessary for short walks, while a lifestyle trainer may be less suitable for long training sessions. So compare the verifiable product specifications first, and only then choose based on colour or brand.
