Choosing blue trainers: how to find a pair for everyday wear and sport

Blue trainers come in many styles, from lightweight models for walking to sturdy skate trainers and blue sports shoes for running or tennis. The colour is often the easiest choice, but differences in comfort, grip and durability mainly come down to the construction.

Anyone who focuses only on the brand, discount or appearance may find themselves with an unsuitable pair after just a few months. So watch out for these three common pitfalls:

  • A fashionable sole is not automatically suitable for sport. Casual trainers may offer too little cushioning or stability for long walks and running.
  • “Breathable” means little without a material description. An upper made from mesh or textile may allow more airflow, but could offer less protection from rain than synthetic material or leather.
  • The wrong size can affect comfort and wear. A shoe that is too short or too wide is more likely to rub and provides less control when moving.

Below, we explain which features to check before buying and which blue trainers suit different uses.

What to look for in blue trainers

1. Choose the sole based on how you will use them

For everyday wear in the city, trainers with rubber soles are practical. According to the product description, rubber provides grip on paved surfaces in various models and is generally suitable for normal walking.

For running, the midsole is at least as important as the outsole. According to the product information, the adidas Galaxy 7 M uses a Cloudfoam midsole for cushioning and a TPU outsole. This makes this type of shoe a more logical choice for road-running sessions than a flat lifestyle trainer.

For skating and streetwear, a sturdy upper, a grippy tread and sufficient protection around the foot are important. According to the product description, the Vans Old Skool has a gum rubber sole with a diamond tread. The Vans Knu Skool features a suede upper and a natural rubber outsole.

2. Check the material and care requirements

An upper made from textile or mesh is often lightweight. The Puma Nova Elite is listed as combining synthetic material and mesh. The product information also mentions a padded insole and rubber sole. These are verifiable features; they do not automatically mean that the shoe is suitable for every type of weather or sport.

Suede and leather require more care. According to Vans’ care instructions, it is advisable to treat the Knu Skool with a waterproofing product before first wear. Machine washing, bleach and harsh cleaners are not recommended. If you want to keep maintenance to a minimum, look for a textile or synthetic model that can be cleaned with a damp cloth.

3. Measure your foot and compare the size chart

Sizes vary by brand and model. So do not look only at the EU size; also check the stated foot length where available. For example, the adidas Galaxy 7 M is listed in size 40 with a foot length of 255 mm, while size 42 has a foot length of 270 mm. Size 41 1/3 is listed with 258 mm, and 42 2/3 with 42 2/3 as the product size.

For Vans, the size chart in the supplied product information runs from EU 36 to 42.5, among other sizes. The stated foot length varies according to the size. Measure both feet at the end of the day, wear the socks you normally use and leave some room around the toes when choosing a sports model. Always check the current size chart on the product page before ordering.

Caring for and replacing blue trainers

Allow wet trainers to air-dry away from direct heat. For textile models, a damp cloth may be sufficient; for suede, follow Vans’ specific instructions. Regularly check the sole, seams and insole. Replace a pair when the sole becomes noticeably smooth, the upper starts to come away or the fit changes.

There is no fixed lifespan that applies to all trainers. How long a pair lasts depends on walking distance, surface, body weight, care and how often you alternate them with other shoes. Ideally, do not use running shoes as everyday work shoes if you use them intensively for training.

Frequently asked questions about blue trainers

Which blue trainers are suitable for walking?

Look for a lightweight construction, a supportive insole and a sole with sufficient grip. The Puma Nova Elite lists these features in its product description. For longer walks, it is advisable to assess the fit and cushioning indoors first.

Are blue trainers also suitable for running?

Not every model. Choose a running shoe with a specified midsole and intended use. According to the product information, the adidas Galaxy 7 M is designed for road running and features Cloudfoam cushioning. A flat Vans Old Skool or Knu Skool is better suited to casual wear and skate streetwear.

How can I keep blue trainers looking good for longer?

Clean them according to the material, allow shoes to dry naturally and avoid bleach and harsh cleaners. Treat suede with a suitable waterproofing product before first wear. Alternating between two pairs gives the materials more time to dry, and trainers generally retain their shape for longer.
