If you’re a sneakerhead, you’d know how difficult it is to get your hands on a pair of limited edition sneaker. It’s not uncommon for people to queue overnight (or more than one night) just to buy a pair of Yeezys. But why go to all the trouble?

Firstly, it’s about owning a pair of limited editions, of course. Secondly, the sneakers have high resale value. In fact, the Kanye West x Louis Vuitton sneakers are currently valued at $38,386—a 2,532% appreciation since its release in 2009.

The Nike SB What The Dunk model, which originally retailed for $153, is now valued at $6,396—a 4,067% increase.

Now that you know whether your limited edition sneaker will earn you money, here comes the question: what makes sneakers so collectable?

Mathieu Le Maux is a French sneaker expert and the author of 1000 Sneakers, opines that some people collect sneakers “to create an ‘emotional heritage’ linked to memories from the past.” He also cited three reasons why sneakers are collectable:

The first one is the “Proust Madeleine effect” (objects taking you back to your childhood).

The second one is the appeal of highly aesthetic objects (such as modern art).

The third one is the allure of investing in something concrete – there is more appeal to investing in beautiful shoes than there is to a completely immaterial stock portfolio that doesn’t inspire any emotions.

Read on for a Q&A with the sneaker expert so you know what sneakers to buy and how to keep them in good condition to increase their resale value.

Does sneaker size affect value? If so, how?

Yes, it’s a possibility. A model in men’s size 42 to 44 (8 to 10 – UK, 9 to 11 – US) will be way more popular because a majority of men are wearing shoes in this range of sizes. It will probably be more expensive to find sneakers in these sizes than for bigger or smaller sizes.

What other factors determine sneaker value?

Its rarity, its condition, the prestige of the designers at that time, and the quality of the material used to create it.

How can you spot counterfeit sneakers?

The best way to spot a counterfeit is to find images beforehand so you can compare it with the model that you want to buy. And to be 100% certain, I recommend to only buy sneakers on referenced websites that are well known for their reliability.

How do you know which sneakers will be good investments?

It’s difficult to know for certain whether a sneaker will appreciate in value. However, there are a few signals that would allow you to “bet” on it. If it’s a limited edition of an iconic model that is revisited by a famous designer or an world-famous artist, it is very likely that its value will increase.

Is it worth selling now or holding onto them?

Here again, there is no absolute truth. It’s just like on the stock market: you need a bit of intuition, some experience and some research on the current trends and upcoming release. Often, if you want to do a nice swing, it’s worth buying the much-anticipated limited editions of famous sneakers as soon as they come out and then selling them right after for more money.

Any tips for keeping sneakers in good condition?

Adapt the sneakers you’re wearing to the occasion or the place you’re going to. For example, don’t wear a model that is precious to you to a party or a concert. You also have to take care of it on a daily basis (use water and soap, avoid any toxic products that can damage the fabric). Recently, “sneakers clinics” have started to appear in which specialists try and save your favourite pair. They are the shoemakers of modern times!
