How to choose men’s trainers without making a costly mistake: check the fit, materials and intended use

A pair of men’s trainers may seem easy to choose, until you wear them around town, to work or for a light workout. That’s when you find out whether they have enough room, let your feet breathe and suit the way you plan to use them. A low price or a familiar brand name alone says little about fit and durability.

The most common pitfalls are:

1. Choosing the wrong size based solely on the EU number. A size 42 can fit differently depending on the brand or model. So check the foot length in centimetres and the stated width too.
2. Confusing “comfort” with a soft insole. A memory foam insole may feel comfortable, but the overall fit, heel hold and sole construction also help determine whether a shoe is suitable for long days.
3. Using sports shoes for purposes they weren’t designed for. Men’s running shoes have different features from casual men’s trainers for everyday wear. A lifestyle model isn’t automatically suitable for intensive running sessions.

What features should you check?

1. Fit, size and foot length

Alongside the shoe size, check the size chart. Some adidas models use half sizes such as 41 1/3, 43 1/3 and 44 2/3. For example, the adidas Run 70s 2.0 lists foot length in centimetres for certain sizes. This makes it easier to compare than relying solely on your usual size.

Look out for the following:

• Leave about a finger’s width of space at the toes.
• Check that your heel doesn’t slip out when you walk.
• Check the shoe width, for example D or regular fit.
• Measure both feet at the end of the day and use the larger measurement.
• Wear socks similar to the ones you normally use.

If you’re looking for size 42 trainers, size 44 trainers or size 45 trainers, it’s worth opening the specific size option for each product. One model may be available in size 44, while another version may only list size 44 2/3.

2. Upper and breathability

Textile, mesh and synthetic leather each have different properties. A textile or mesh upper may feel lighter and airier. Synthetic leather is often easier to wipe clean and has a more enclosed look. The product information should clearly state which materials the shoe uses.

Breathable panels are practical for warm days or plenty of walking. However, textile isn’t automatically waterproof in rainy weather. So don’t buy a shoe just because it’s described as “breathable” if what you really need is protection from the rain.

3. Sole, grip and intended use

A rubber outsole generally provides grip on everyday surfaces, but the tread and construction matter too. Check whether the shoe is designed for walking, everyday wear, training or running.

Men’s running shoes are designed with different priorities from black men’s trainers for the office and leisure. A product description may mention features such as cushioning, flexibility or shock absorption. Present these as product specifications or brand claims: according to adidas’s own product information, the Run 70s 2.0 is lightweight and flexible, with a rubber outsole. This doesn’t guarantee that every wearer will have the same experience.

Frequently asked questions about men’s trainers

How do I find the right size in men’s trainers?

Measure your foot in centimetres while standing upright, then compare it with the size chart for the specific model. Check the width too, and read the sizing advice. A size 44 from one brand may not have the same internal measurements as a size 44 from another.

How long do men’s trainers last?

Their lifespan depends on how far you walk, the surface, your body weight, care and how often you wear them. With everyday use, the sole tread and heel will usually wear down faster than with occasional wear. Alternate between pairs, allow damp shoes to dry thoroughly and follow the manufacturer’s care advice. Don’t machine-wash a model if the product information advises against it.

Can I wear casual trainers for running?

This is generally not recommended if the model isn’t listed as a running shoe. Casual men’s trainers are designed for everyday wear and light activities. If you run regularly, look for a suitable fit, running category, sole construction and clear product information for the specific model.
