THE LIFE CYCLE OF TRAIL RUNNING SHOES: WHEN TO REPLACE THEM AND HOW TO REDUCE THEIR ENVIRONMENTAL IMPACT

Every training session and every race leaves its mark on our trail running shoes. Knowing when they have reached the end of their useful life, and how to extend it or dispose of them responsibly, is also part of our commitment to the mountains.

Much more than just a pair of shoes

Trail running shoes are one of the most important pieces of kit for any mountain runner. They accompany us over hundreds of kilometres, braving mud, rocks, sand, elevation gain and all kinds of weather conditions.

However, like any sports equipment, they have a limited lifespan. Over time, they lose cushioning, grip and stability, which can affect both performance and runner safety.

Knowing when it is time to replace them, and what to do with them afterwards, is part of practising the sport responsibly.

How long do trail running shoes last?

There is no exact figure.

Their lifespan depends on several factors:

The type of terrain you train on.
The cumulative elevation gain.
The runner’s weight.
Running technique.
How often they are used.
The quality of the materials.

As a general guide, many trail running shoes perform well for around 600 to 1,000 kilometres, although some models may last longer and others less depending on how they are used.

That is why it is worth looking beyond mileage alone and checking the real condition of the shoes.

Signs it is time to replace them

You do not always need to wait until your shoes are completely falling apart.

There are several signs that they have lost much of their performance:

A heavily worn outsole with reduced grip.
Less effective cushioning.
A deformed midsole.
Open or peeling seams.
A greater sense of impact while running.
New aches or niggles that were not there before.

Continuing to run in overly worn shoes can increase the risk of injury and reduce safety on technical terrain.

Can they be repaired?

In some cases, yes.

Small repairs such as replacing the laces, reinforcing seams or re-gluing certain areas can extend the shoes’ useful life by a few months.

Although not all shoes allow for more extensive repairs, looking after your kit properly, cleaning it after runs and leaving it to dry naturally will help preserve it for longer.

Extending the life of a pair of shoes also means using fewer resources and creating less waste.

Giving them a new lease of life

When a pair of shoes is no longer suitable for running, that does not necessarily mean they are no longer useful.

Many runners use them for low-impact activities such as walking, gentle hiking, outdoor strength training or everyday jobs.

This small change helps delay their final replacement and makes better use of all the materials used to produce them.

And when they’re no longer any use?

When shoes have genuinely reached the end of their useful life, it is best to avoid throwing them in with household waste.

More and more brands, specialist shops and recycling schemes collect sports footwear to give it a new use.

The materials can later be turned into sports surfaces, cushioned flooring or new products, helping to reduce environmental impact.

Many local councils also provide recycling centres where this type of waste can be disposed of properly.

Running also means caring for the environment

Those of us who love trail running know what a privilege it is to move through paths, woods and unique natural spaces.

That is exactly why small decisions, such as extending the life of our kit, recycling shoes properly or choosing more sustainable options, are also part of showing respect for the mountains.

Because our commitment to nature does not end when we cross the finish line.

It continues in everything we do after each run.
