Choosing trainers and running shoes: practical tips for comfort, fit and use

A pair of trainers can look great in photos yet disappoint as soon as you wear them around town, to the gym or over longer distances. When buying trainers and running shoes, many shoppers focus mainly on the brand, colour and discount. These are useful considerations, but they reveal little about fit, grip or whether the shoes are suitable for how you intend to use them.

The most common purchasing pitfalls are:

  1. Using casual trainers for running. A flat rubber sole may be perfectly suitable for everyday use, but it does not automatically provide the cushioning, stability or grip you need when running.
  2. Looking only at the shoe size. An EU size can feel different depending on the brand, model and fit. You should therefore also check the foot length in centimetres or millimetres.
  3. Confusing marketing terms with measurable features. Words such as “performance”, “comfort” or “all terrain” only become meaningful when the product description also specifies the materials, sole type and intended use.

Which features should you check?

1. Fit and available sizes

A good fit starts with measuring your feet correctly. Measure your feet at the end of the day while wearing the socks you normally use. Compare the measurement with the size chart for the specific model.

Pay attention to:

  • Foot length in cm or mm: some adidas models list this measurement alongside the EU size.
  • Width and fit: a regular fit is not automatically suitable for a wide foot.
  • Toe room: when running, a little extra room for your toes is practical.
  • Laces or hook-and-loop fastening: laces offer more adjustability, while hook-and-loop fastening is convenient for children and quick changes.

A model can be the correct size yet still pinch if the fit is unsuitable. Always check the returns policy and try shoes on indoors on a clean surface.

2. Cushioning suited to the activity

Cushioned sports shoes are not all designed for the same purpose. For walking, fitness and everyday use, a lightweight EVA or synthetic midsole may be sufficient. For running, the midsole construction, weight and flexibility are more important.

  • Everyday use: look for a soft insole and a sole that allows a comfortable foot roll.
  • Fitness and training: a stable base and sufficient grip are often more important than maximum softness.
  • Running: check the foam used, the flexibility and the support around the midfoot.
  • Long walks: a breathable upper and rubber outsole can be helpful on changing surfaces.

Technology names such as Lightstrike Pro, Dreamstrike or SoftFoam+ describe the construction according to the product information. Your personal experience may vary depending on your weight, running style and the surface.

3. Upper, sole and care

A textile or mesh upper may feel more breathable than synthetic material. That does not automatically make it suitable for rain. Check the sole as well:

  • Rubber: generally intended to provide grip and durability on hard surfaces.
  • Rubber studs or tread: may offer more traction on uneven ground.
  • Continental Rubber and Lighttraxion: these features are listed in the product descriptions for certain adidas Adizero Boston 13 models.
  • Leather or suede upper: offers a different look, but generally requires more care than mesh.

Most of the models listed should not be washed in a washing machine. The product descriptions generally recommend wiping them with a damp cloth and allowing them to air-dry away from direct heat. This helps minimise fading and deformation.

Other popular options to compare

If you are mainly looking for black trainers for everyday wear, you could also consider the Vans Authentic in black. This model has a textile upper, textile lining and rubber sole. The Vans Rowley Classic adds a suede upper and the familiar waffle sole.

For a lightweight shoe for the gym, shopping or casual wear, the product information for the PUMA Anzarun Lite lists a mesh upper, EVA midsole, rubber outsole and SoftFoam+ insole. The PUMA Speedcat OG, by contrast, has a leather upper, IMEVA midsole and rubber sole.

There are also different intended-use profiles among adidas running shoes. According to its description, the Supernova Ease is designed for short to medium daily runs and uses a Dreamstrike midsole with breathable mesh. The Supernova Rise M ATR has a more versatile design for a range of activities. The adidas Run 70s 2.0 is more of a casual model with a retro look than a dedicated running shoe.

For men, women and children, it is sensible not to rely solely on the “M”, “W” or “unisex” designation. Always check the foot length, fit and available size. For example, the Skechers Go Run 400 for children has a hook-and-loop fastening and mesh upper, while the Skechers D’Lux Walker for men lists a regular fit, textile upper and rubber sole.

Frequently asked questions about trainers and running shoes

How long do trainers and running shoes last?

That depends on usage, weight, surface and care. Look for wear on the tread, tears in the upper and a midsole that has visibly or noticeably compressed. With running shoes, appearance is not the only consideration: reduced cushioning or an unevenly worn sole may indicate that it is time for a replacement.

Can I use ordinary trainers for running?

For a short, gentle walk or occasional training session, casual trainers may seem practical. For regular running, a model with a suitable running construction, breathable upper and cushioning is generally the more sensible choice. Choose shoes based on the activity you will use them for most.

How do I clean trainers without damaging them?

Remove loose dirt with a soft brush and wipe the surface with a damp cloth. Use mild soap when this is permitted by the care instructions. Allow shoes to air-dry and avoid the washing machine, bleach and direct heat unless the label for the specific model states otherwise.
