These 10 ultra-popular sneakers are leading an explosion in the resale market

• Sneaker resale is booming. It's now estimated to be a $2 billion market, according to Cowen & Co. estimates.
• That market is projected to triple in size over the next several years, reaching more than $6 billion by 2025.
• With the help of StockX, Cowen compiled a list of the most sold sneakers on the platform over the last year.

Sneaker collecting is becoming an increasingly common pastime, and it's fueling a secondhand market that is exploding.

Sneaker resale is now estimated to be a $2 billion market, according to Cowen & Co estimates. It's projected to triple over the next several years, reaching more than $6 billion by 2025.

Almost all of that market is led by sneakers produced by Nike and, to a lesser extent, Adidas, which create rare and highly sought-after models that command prices reaching as high as $50,000.

While sneaker resale started out as a way to cop extremely rare, collectible kicks, most of the shoes actually sold in this way are less than $300 and have been restocked multiple times, according to StockX data provided to Cowen. The data covered StockX's most popular models in the 12 months ending in March.

Another observation: seven out of the 10 most commonly resold shoes are made by Adidas, specifically its Yeezy sub-brand in collaboration with Kanye West. The other three are made by Nike, but, again, specifically by its Jordan sub-brand that started as a collaboration with Michael Jordan.

Here were the most commonly resold sneakers in the last year:
