Our guide to buying and selling second-hand running shoes

Made a goal or a New Year’s resolution to finally take up running? You’re not the only one; 23% of Britons start the year with the intention of getting fit and exercising. However, 24% fail all of their resolutions. Often the hardest part is getting started, and with running, that means finding the right shoes.
Perhaps you’ve bought running shoes that don’t feel comfortable and want to sell them on. Or maybe you’re new to running, but a brand-new pair feels like an expensive commitment for a new hobby. While the latest running shoes can be expensive, a second-hand pair gives you an affordable way to get off on the right foot.
In this guide, we share tips on buying and selling second-hand running shoes, from when to replace a pair to how to recycle the ones you no longer need.
Buying second-hand running shoes
When should you replace running shoes?
There’s the “300–500 miles rule”, which is generally how long trainers should last. Though this depends on the surface you’re running on, along with your running style and what they’re used for. For example if they’re racing shoes, then this is around 250–300 miles, whereas trainers used daily or for trails follow the 300 to 500 miles rule.
Along with running distance, you can tell when footwear needs to be replaced by looking for some telltale signs, like a worn outsole, a hard midsole foam, deep creases in the midsole foam or a floppy or collapsed heel. If you keep getting new blisters or sore spots, then this signals that the shoe’s shape has changed. Likewise, if you have unexplained joint pain or running feels more difficult than previously, you should check for issues with your trainers.
Will second-hand running shoes last?
Whilst it depends on the pair, there are plenty of second-hand running shoes that will only have had light-use before the original owner decided that the pair wasn’t suitable for them. It’s a common story where someone buys trainers, uses them and then unfortunately discovers they’re just not right due to problems like rubbing or blisters. As they’ve been used, unless there is a manufacturing defect they can’t be returned. And so, it’s common to find second-hand newish and barely worn running footwear.
What’s important is to look at the indicators mentioned in the above section, which can reveal more about the prospective lifespan for the shoes.
Can you get second-hand children’s shoes?
Particularly with children’s sports shoes, these can sometimes be bought, hardly worn and then they’ve already grown out of them! In fact, children aged 5–12 require new shoes at least once per year due to their feet going up on average by one shoe size. Therefore, children’s second-hand trainers are worth getting as these can often be almost as good as new.
Can you buy any type of sports footwear second hand?
Any type can be both bought or sold, providing they’re in good condition, hygienic and clean. This includes cycling shoes, rugby boots, plimsoles and hiking footwear.
If you already know a particular model fits you well, that can help narrow your search. Before buying, ask the seller for the exact model, size and width, an estimate of how far the shoes have been worn, and clear photographs of the soles, heels and insides. Ask whether they were used for running, walking or both, and whether the original insoles are included.
Selling and recycling second-hand running shoes
Can shoes be recycled?
While you can recycle shoes, how to do so depends on your location. Some councils allow for at-home recycling if they’re provided in a specific container (like a householder provided carrier bag), or you may need to find an out-of-home recycling point. Search for one near you using the Recycle Now website.
How much can you sell running shoes for?
If you’re joining the 42% of Brits selling their items online, then you’ll need to research pricing. Look at whether the shoes have been sold before via online seller platforms, such as Causee, and whether they’re comparable. For example, you’ll need to consider their age, usage, condition and original retail price.
It’s worth noting that sometimes runners find the perfect fit and shoe, but then sports manufacturers stop making that particular line. If this happens, sometimes the value can skyrocket if the shoe is well-known and in good condition. So, you should always check if your trainers are still being produced. If not, then you can set a higher price!
Can you sell running shoes in any condition?
Sometimes trainers can simply be too far gone to be hygienic to sell (for example if they had an odour or have developed damp or mould), or they’ve been worn so much that they don’t have the necessary ‘bounce’ for shock absorption and energy return. They need to be in a good, wearable condition for sale so if you think your shoes aren’t in great condition then it’s best that you recycle them instead.
How do you clean running shoes before selling?
Always follow the manufacturer's care instructions for the shoes. But in general hygiene is extremely important whether you’re selling shoes or trying to extend their life as good cleaning can help running footwear last much longer. You’ll need to do so carefully and by hand, as machine washing could warp the trainers or damage the material. Make a gentle cleaning solution (a small amount of soap mixed with warm water will do), then scrub them with either a soft-bristled brush, toothbrush or damp cloth.
For drying, we recommend air drying them or using a fan rather than any form of heat as this distorts foam and weakens glue. You should also stuff them with crumpled newspaper or kitchen paper to soak up the excess moisture. Removing the insoles and loosening the laces will enable better airflow and speed up drying.
How do you list running shoes for sale?
As well as cleaning them so they’re in the best condition, we suggest photographing the shoes against a plain background. Ensure you capture various angles, any flaws and the size label. In terms of the description, you should be honest about their condition and estimate how much mileage they’ve done. Include any details you know, like the brand and model name.
Where can you list running shoes for sale?
There are numerous platforms, though Causee has the extra benefit of being an ethical marketplace. While sellers keep 100% of the sale price, Causee uses the fees paid by buyers to cover its operating costs, invest in improving the platform and maintain appropriate financial reserves. All remaining distributable profits are committed to supporting charities and good causes, with buyers and sellers helping to decide where at least 80% of those profits go.
