For experienced or novice sneakerheads, attending sneaker events is just one part of hacking the sneaker resale industry, which a recent Cowen & Co. analysis estimated could be worth $6 billion globally by 2025.

Sneaker Con is iconic among the various events there are for buying and selling sneakers.

Billing itself as "the greatest sneaker show on earth," Sneaker Con draws thousands of sneakerheads to its gatherings, which occur multiple times a year in different locations around the world. For buyers, Sneaker Con and similar shows are a great place to barter for desirable shoes. For sellers, they're ideal for making business relationships and a sizable profit in just a few days.

Jeremiah Jiang started reselling sneakers during his freshman year of high school. The 19-year-old says says he made $230,000 in sales in 2018 and $350,000 in sales last year.

Though Jiang conducts a lot of business through his Instagram, @thesneakerassociate, he says that sneaker events are an important way to make connections and profit. The San Jose, California, native goes to more than 10 US sneaker events a year as a vendor, aiming to sell between 30 and 50 pairs at each. By limiting his expenses to between $800 to $1,000 per event, Jiang says he manages to pull in an average profit of more than $2,500 in just one to two days.

But when Jiang started attending sneaker events in high school, he said he usually left with little profit.

"I wasn't planning that well," he said. "I was very inexperienced."

After attending more events, Jiang learned that he needed to plan one to two months in advance to make the most out of his time there. Eventually, these types of events became major boons to his business.

Jiang shared the spreadsheet he used to maximize his profit at a sneaker event in California, outlining exactly what he spends during a sneaker event.
