How to Choose the Right Trainers and Sports Shoes: Buyer's Guide

The world of trainers and sports shoes is a constantly evolving maze. Between trendy sneakers for the city and ultra-technical models for performance, it's easy to get lost. A poor choice isn't just money down the drain; it's also a risk of discomfort, or even injury.

As the head of product selection at Joybuy, my mission is to help you make sense of it all. This guide breaks down the common mistakes and highlights the criteria that truly matter, guiding you to the pair that's perfectly suited to your needs.

The 3 Pitfalls to Avoid When Buying Shoes

Before you even start looking at models, let's review the most frequent errors that turn a purchase into a regret.

  1. The myth of the do-it-all shoe. A pair of fashion sneakers, even with a great design, is rarely built for regular athletic activities like running. Their structure simply isn't designed to absorb the repeated impact of a run, which comes at the expense of your joints.
  2. Cushioning that vanishes after a few weeks. Many entry-level shoes rely on a low-density EVA (ethylene-vinyl acetate) foam for their midsole. While the comfort might feel great in the store, this foam has an unfortunate tendency to compress and lose its cushioning power in just a few weeks, leaving your feet without any support.
  3. Ignoring the outsole design. A smooth, flat outsole, typical of lifestyle sneakers, offers very limited grip on wet or uneven surfaces. Whether for sports or simply for walking safely day-to-day, the material and tread pattern of the outsole are non-negotiable features.

Key Criteria to Check Before You Buy

To make the right choice, you need to focus on three technical components that make all the difference in performance, comfort, and durability.

The Midsole: The Heart of Comfort

This is the layer nestled between your foot and the outsole. Its job is to absorb shock and ensure stability. Beyond basic EVA foam, look for more durable technologies:

  • High-density foams: These provide better energy return and increased longevity.
  • Proprietary technologies: Brands like New Balance with its ABZORB system or Nike with its Air units develop specific materials and designs for targeted, long-lasting cushioning.

The Outsole: Your Point of Contact with the Ground

It must be designed for your primary use. A running shoe will feature high-abrasion rubber reinforcements in key areas, while a model for indoor sports will integrate pivot points to facilitate changes in direction. For daily wear, an outsole with deep grooves ensures better water displacement and therefore enhanced grip.

The Upper: Balancing Breathability and Support

The top part of the shoe, known as the upper, has a direct impact on comfort and foot support.

  • Mesh uppers: Ideal for sports and warm weather, they promote air circulation to keep feet dry.
  • Leather or synthetic uppers: These provide better support, superior durability, and enhanced protection. They are the perfect choice for work shoes or long city walks.

Frequently Asked Questions

What is the average lifespan of a pair of running shoes?

The lifespan of a running shoe is measured in miles, not months. As a general rule, it's recommended to replace them every 400 to 500 miles (600 to 800 kilometres). The tell-tale signs? An outsole that's becoming smooth, a feeling of diminished cushioning, or the appearance of unusual aches and pains after your runs.

Can you wash trainers in a washing machine?

That's a very bad idea. Machine washing is strongly discouraged for most trainers. The heat and tumbling can warp the shoe, unglue the soles, and damage the technical materials. It's much better to opt for hand-cleaning with a soft brush, cold water, and a neutral soap (like castile soap). Remember to remove the laces and insoles to wash them separately.

How do you choose the right size for sports shoes online?

The most reliable method is to measure your foot in centimetres. Place your foot flat on a sheet of paper, trace its outline, then measure the distance from the heel to your longest toe. Then, compare this measurement to the brand's size chart, which often provides the corresponding length in CM or JP. Our tip: take this measurement at the end of the day when your feet have swollen slightly, and wear the same type of socks you'll use with the shoes.
